It has become the primary beam tool for many groups including several CERN based experiments, largely due to its precise resolution, reliable operation and DAQ integration capabilities. For the telescope to deliver this excellent performance, two software packages play a central role: EUDAQ, a multi-platform data acquisition system that allows easy integration of the device-under-test, and EUTelescope, a group of processors running in ILCSoft's Marlin framework that allows the spatial reconstruction of particle tracks and the final data analysis. Although both software packages have been used successfully in test beams for many years, they are under constant development: integrating new device types and use-cases, extending usability and flexibility, and supporting new features such as the high-rate capabilities of the next-generation pixel beam telescope developed within the new European detector infrastructure project AIDA. In this contribution, we present the features of the current releases of both EUDAQ and EUTelescope, show-case the application of the frameworks within other projects, and discuss the plans for development toward an easy to use software stack with the capability for high particle and data rates.

The detector will consist in 20 close-packed single modules, each of them coupled to two photomultipliers (PMTs) working in coincidence. An electronic chain and data acquisition system (DAQ) have been developed to provide a redundant readout at different dynamic ranges and to digitize the PMT signals with high temporal and vertical resolution in the low energy region, that have allowed the implementation of new algorithms for noise discrimination by pulse shape analysis. We present the design of the whole DAQ system and its characterization (stability and trigger efficiency, baseline noise reduction, dead time precise measurements, performance of homemade preamplifiers, integration with the slow control and warnings system...). Finally, preliminary results on photomultiplier response, light collection and energy resolution obtained with several prototypes are also presented.

The operation and the results obtained from the data collected 2011 and 2012 demonstrate that the current detector is robust and functioning very well. However, the limit of $\mathcal{O}($1 fb$^{-1}$) of data per year cannot be overcome without improving the detector. After 2018, it is planned to run with an increased luminosity of $\mathrm{1-2\times10^{33}\ cm^{-2}s^{-1}}$ to collect up to 50 fb$^{-1}$ of data. This will be achieved using 25 ns bunch spacing with the average number of proton-proton interactions per bunch crossing $\nu=3.8-7.6$. Collecting data at this luminosity will only be possible if the detector is improved by increasing the readout of the front-end electronics to 40MHz and implementing a more flexible software-based triggering system that will increase the data rate as well as the efficiency. The increase in interactions per bunch crossing will result in an increased occupancy in the tracking detectors and will exceed the operational occupancy for the Outer Tracker. Here we present the SciFi Tracker as the replacement for the Outer and Inner Trackers. The SciFi Tracker is based on 2.5 m long multi-layered ribbons from 10,000 km of 0.250 mm diameter scintillating fibre as the active medium and signal transport over 12 planes covering 350 m$^{2}$. Cooled silicon photomultiplier (SiPM) arrays with 128 channels and 0.25 mm channel width are used as readout. The front-end electronics are designed to digitize the signals from the SiPMS with a custom ASIC chip, the PACIFIC, for the approximately 560,000 channels and reconstruct the track hit position within an on-board FPGA. Several challenges facing this detector will be presented regarding the precision construction of the large active detector components, the radiation hardness of the scintillating fibres and the SiPMs, the high density readout electronics, and the necessary cooling systems.

Citiroc allows triggering down to 1/3 pe and provides the charge measurement with a good noise rejection. Moreover, Citiroc outputs the 32-channel triggers with a high accuracy (100 ps). An adjustment of the SiPM high-voltage is possible using a channel-by-channel DAC connected to the ASIC inputs. That allows a fine SiPM gain and dark noise adjustment at the system level to correct for the non-uniformity of SiPMs. Timing measurement down to 100 ps RMS jitter is possible along with 1% linearity energy measurement up to 2500 p.e. The power consumption is about 2mW/channel, excluding ASIC outing buffer Summary Citiroc is a new ASIC designed by Weeroc, a start-up company from the Omega microelectronics group of IN2P3/CNRS. Each channel of this new ASIC embeds a front-end read-out chain composed of two AC-coupled voltage low-noise preamplifier with variable-gain adjustment. The utility of the gain tuning on the preamplifiers is twofold. On the first hand it allows to compensate non-uniformity between channels by finely adjusting gain channel by channel, on the second hand, it allows to adjust the general gain of the amplification chain to adjust the read-out chain to the SiPM gain, allowing a large choice of SiPM on the system to be used. Citiroc has a new channel-by-channel trigger chain composed of a fast shaper followed by two discriminators with individual channel-by-channel threshold adjustment to be able to trig on the first photo-electron and validate the trigger on the first few photoelectrons. That double trigger allows a great dark noise rejection at the first stage of the read-out chain and avoids saturating the DAQ with noise events. Each trigger channel can be masked in case of noisy channel, latched, or output the discriminator output as is depending on user needs. A general ASIC trigger is also outputted through a 32-input trigger OR. Citiroc energy measurement is composed of two variable-gain shapers to get energy measurement from one to 2500 photoelectron with 1% linearity. Charge proportional to energy can be stored in an analogue memory using either an analogue memory or a peak-sensing detector to get rid of the hold signal versus trigger delay. A channel-by-channel input DAC allows adjusting the high voltage of the SiPM over 5V with 8-bit resolution to correct for SiPM over-voltage non-uniformity. Citiroc outputs 32 trigger outputs as well as a multiplexed tri-state hit-register to allow several Citiroc to be serialized on a single hit-register serial bus. Citiroc outputs two multiplexed analogue outputs to read-out the charge on both low and high gain to ease the low-gain and low-gain channel inter-calibration. Citiroc also embed a general 10-bit DAC for coarse general threshold adjustment. Voltage references in the ASIC are done with a bandgap to improve power supply rejection ratio and temperature sensitivity of the ASIC. Citiroc is aimed to be mounted very close to the SiPM in the systems it will be used in. A temperature sensor has been embedded to allow users to finely sense the temperature within their multi-channel system to correct for SiPM gain over voltage adjustment with temperature. As a conclusion Citiroc has been designed to be as versatile as possible for SIPM read-out. It is aimed to be used in large system and has been optimized to ease the SiPM adjustment and reduce has much as possible the data flow through the DAQ by filtering the SiPM noise at the front-end level. Citiroc will be used in a first telescope prototype for the CTA experiment and is aimed to be used in medical systems such as PET or gamma cameras using SiPM. A test board with ergonomic GUI software is available for Citiroc evaluation.

The system detects Cherenkov photons produced by charged particles passing through one of 16 quartz bars arranged in a barrel around the inner tracking detectors. An array of 32 pixelated micro-channel plate photomultipliers (MCP-PMTs) instrument each bar to detect internally reflected photons with time resolution better than 50ps. A waveform sampling ASIC-based frontend readout electronics system digitizes and measures photon detection times. Photon time information is combined with tracker data to reconstruct the charged particle’s Cherenkov ring image for use in particle identification analysis. The ability to distinguish between kaons and pions with high sensitivity will be crucial in many Belle II physics measurements. This presentation will describe the TOP detector design and application in physics analyses, and summarize current detector development activities and plans leading up to installation in early 2015.

The final upgrade is planned for around 2023, followed by the HL-LHC running. This is motivated by the need to harvest the maximum physics potential from the machine. It is clear that the high integrated luminosity of 3000 fb-1 will result in very high radiation levels, which manifest a serious challenge for the detectors. This is especially true for the tracking detectors installed close to the interaction point. For HL-LHC, all-silicon central trackers are being studied in ATLAS, CMS and LHCb, with extremely radiation hard silicon sensors to be employed in the innermost layers. Within the RD50 Collaboration, a massive R&D program is underway, with an open cooperation across experimental boundaries to develop silicon sensors with sufficient radiation tolerance. One research topic is to study sensors made from p-type silicon bulk, which have superior radiation hardness as they collect electrons instead of holes. A further area of activity is the development of advanced sensor types like 3D detectors designed for the extreme radiation levels expected for the inner layers. We will present results of several detector technologies and silicon materials at radiation levels corresponding to HL-LHC fluences. Observations of charge multiplication effects at very high bias voltages in a number of detectors will be reported. Based on our results, we will give recommendations for the silicon detectors to be used for LHC detector upgrades.

Numerous practical applications have demonstrated and exploited the sensitivity of diamond to charged particles, photons and neutrons. In this presentation, emphasis will be given to fast beam loss monitoring at the LHC and to neutron detection, where diamond can potentially be used as an He-3 replacement. Summary Diamond detectors have proven to be useful as fast beam loss instrumentation. At the LHC bunch-by-bunch losses are resolved and lead to new insight into the behaviour of the accelerator. Recent research has shown that diamond is also a proper candidate for neutron detection, where it proves to be a potential candidate to replace He-3 in the future.

The RICH system is an integral part of LHCb proving hadron identification in the momentum range of 2-100 GeV/c. The ability to separate pions and kaons in this wide momentum range is essential for the physics measurements of LHCb. The LHCb RICH system consists of two RICH detectors with three different radiators. The optical systems are made from a total of 116 mirrors (four constructed out of low mass carbon fibre) and single photon detection is achieved by 484 Hybrid Photon Detectors (HPD). The RICH detectors have been aligned and calibrated using the LHCb data and their performance evaluated using pure particle samples collected without RICH information. The performance of the RICH detectors in a high multiplicity hadron environment is excellent. The LHCb experiment is preparing for a significant upgrade during the Long Shutdown 2 of the LHC. There are advanced plans to modify the existing layout in order to conserve the current particle identification performance despite the increase in luminosity by a factor five. The alignment, calibration and performance of the LHCb RICH system will be presented, together with a few example analyses showing the contribution of the RICH. The plans for the LHCb RICH upgrade will also be presented. Summary Primary Authors: Dr. PAPANESTIS, Antonis (STFC - Rutherford Appleton Lab.

To guarantee high sensitivity near the collision point, modern particle tracking systems may feature 100 million channels, or pixels, which need to be individually connected to read-out chains. Silicon pixel detectors are typically connected to readout chips by flip-chip bonding using solder bumps. The electrical and mechanical quality of the flip-chip interconnects are important for the proper functioning of the particle tracking system in order to minimize the number of dead read-out channels. Furthermore, the detector modules must be robust enough to endure the handling during the installation and the heat generation and the cooling during the operation. The silicon pixel detector modules were constructed by flip chip bonding 16 readout chips to a single sensor. Eutectic SnPb solder bumps were deposited on the readout chips and the sensor chips had TiW/Pt thin film UBM (under bump metallization). The modules were assembled at Advacam Ltd operating at Micronova Nanofabrication Centre. We studied the quality and uniformity of the interconnections using Scanning White Light Interferometry (SWLI), stylus profiler and performing destructive pull-strength tests. Furthermore, we compared the results of the characterization of interconnections to those of module performance measurements. According to our results, the Ni/SnPb-TiW/Pt interconnections are excellent for flip-chip bonding pixel detector modules.

After having demonstrated the capabilities of the measurement methods in "physics prototypes", the focus now lies on improving their implementation in "engineering prototypes", that are scalable to the full linear collider detector. The Analog Hadron Calorimeter (AHCAL) concept is a sampling calorimeter of tungsten or steel absorber plates and plastic scintillator tiles read out by silicon photomultipliers (SiPMs) as active material. The front-end chips are integrated into the active layers of the calorimeter and are allowing the prototype to be equipped with different types of scintillator tiles as well as SiPMs. Four of the currently available eight layers have been equipped with a novel design of scintillator tile wrapped in reflecting foil and directly coupled to a KETEK SiPM. The blue sensitive SiPM has 2304 pixels, an average gain of 600k electrons and an average dark count rate of 200kcps when operated at 2.5V above breakdown and 22°C. Furthermore the temperature dependence of the breakdown voltage for these SiPMs is only 17 mV/°C, which ensures a stable operation. The operation at fixed overvoltage ensures a homogeneous response and behaviour of the calorimeter. Results from recent beam test measurements of minimal ionizing particles will be compared to calibrations obtained in the lab and the analysis on electromagnetic showers will be presented. Plans for future hadron beam tests with a larger prototype will be discussed.
