Among the sub-detector systems in AILCE, there are two types of calorimetry in the central barrel. One is EMCal (Lead-Scintillator, a sampling electromagnetic calorimeter with a WLS fiber and APD readout), having a wide geometrical acceptance to measure jets, and photons and neutral mesons with a moderate energy resolution. Another type of calorimeter is PHOS (PHOton Spectrometer), PbWO$_4$ crystal with APD readout for high granularity and higher precision energy measurement for photons. In this talk, we review those detectors performance in ALICE, and show ongoing upgrade projects in calorimetry, such as 1) DCAL (Di-jet Calorimeter), an extension of EMCal coverage to measure back-to-back jets, 2) PHOS upgrade to achieve 50 kHz readout speed in minimum bias Lead-Lead collisions at LHC-Run-2. Furthermore, we present an upgrade proposal for the forward direction calorimetry, FOCAL, to measure direct photons in $\eta = 3.3 - 5.3$, by using a nobel technology of silicon photo-diodes with absorbers based electromagnetic calorimeter for photons, together with a conventional hadron calorimeter for jets. The current status of FOCAL R\&D project will be presented.

Abstract content The MOLLER collaboration is currently preparing an experiment to measure the Weak charge of the electron to a fractional accuracy of 2.3% at very low momentum transfer, using parity violating electron scattering. At this precision, the experiment will be sensitive to the interference of the electromagnetic amplitude with new neutral current amplitudes as weak as $10^{-3}\cdot G_{F}$. The experiment will take place at Jefferson National Laboratory, in Newport News Virginia, USA. The experiment will measure the asymmetry in the number of 11 GeV polarized electrons scattered from electrons in a liquid hydrogen target, as a function of electron helicity. The asymmetry has a Standard Model predicted size of 35 ppb (part per billion). Together with the goal precision this requires a high luminosity beam which, at low momentum transfer and very forward scattering angles, leads to detector event rates at the level of GHz/cm2. This requires either very high detector segmentation or current mode operation. The experiment will need to employ several detector technologies, including tracking detectors and current mode detectors. The challenges we face regarding detector design include radiation hardness (up to 15 MRad in certain regions), low noise and high efficiency operation (light yield), and background sensitivity. We are currently exploring highly segmented quartz Cherenkov detectors for current mode operation and GEM technology for tracking detectors. I will provide an overview of the current detector design, including specific challenges we are facing, as well as some results from initial prototype tests.

It consists of a crystal and PMT setup that is read-out using fast ADC and FPGA technology. The maximum dead-time has been established at 1.14 us and the energy resolution at 662 keV is 7%. Full spectral analysis has been implemented for naturally occurring radioisotopes of Potassium, Thorium, Uranium, Radon and their progeny. Further developments, including pile-up correction, neutron detection and miniaturization will be discussed. This technology allows the production of sensor nodes that can be used in many applications. Special attention will be given in to sensor nodes for measurements in hard to reach environments. Environmental monitoring in remote regions of Canada will be discussed as an example as well as precision farming, nuclear reactor monitoring and mining.

It delivers proportional and fast signals, achieves high efficiency to minimum ionising particles with a compact design and shows well-uniform performance over meter-square areas. The current R&D focuses on large-size spark-protected Micromegas with integrated front-end electronics. It targets an application at future linear colliders (LC) and possible upgrades of LHC experiments for the running at high luminosity. Prototyping work and characterisation results will be reported with a special emphasis on the impact of the resistive layer on the calorimeter signals. Summary A few technologically-advanced prototypes of 1x1 m2 were constructed. Optimised for Particle-Flow hadron calorimetry at a LC, they are segmented into pads of 1x1 cm2, each read out by simple threshold electronics. Their standalone performance were studied in great details in testbeams. In addition, expected performance of a Micromegas calorimeter were deduced from the measured three-dimensional shape of high-energy pion showers inside the CALICE semi-digital hadron calorimeter (SDHCAL). Absorption in the gas of highly ionising particles produced in hadron showers occasionally triggers a discharge. This can be a serious show-stopper for high-rate applications such as forward calorimetry at a high-luminosity LHC experiment. Discharge protections based on resistive films were successfully implemented on small-size prototypes. Several resistive configurations were actually studied to minimise the time necessary for charge evacuation and the resulting efficiency and linearity losses.

In order to improve the ALICE physics capabilities, the apparatus will be substantially upgraded during the LHC Long Shutdown 2 (LS2). In particular, the Inner Tracking System will be replaced by a new detector based on an innovative radiation tolerant monolithic active pixel sensor (MAPS) of recent conception, whose R&D is now well advanced. This talk will focus on the first large scale pixel chip prototype, ALPIDE (ALice PIxel DEtector), developed with this new technology, which is one of the options for the new ITS. As peculiar to MAPS, the pixel chip integrates in the same substrate both the sensing diode elements and the Front End Electronics with 28 um pixel pitch. The use of a monolithic pixel sensor allows to achieve very little material budget in the tracking layers, which can be as low as X/X0=0.3% for those closest to the interaction point. The FEE is designed in the 180 nm CMOS TowerJazz technology taking advantage of deep p-well implants. The deep p-well implants allow to reduce significantly the charge collection competition between PMOS transistors and sensing diodes, and allow to have smaller readout circuitry, which can then be placed inside each pixel. The pixel sensor has a data driven readout architecture based on in-pixel discrimination and on a priority-encoding scheme, which makes it compatible with the 50 KHz interaction rate foreseen for Pb-Pb at the LHC.

The planes are separated into modular detectors, each with cooled silicon photomultiplier (SiPM) arrays for photo-readout. In this talk, we will present the construction and performance of this novel detector, including the intricacies of scintillating fibre ribbon production, constructing precision detector planes with a rigid and light module design, and the integration of the readout components for this detector.

Over 10,000 km of fibre will turned into precision detector elements. The performance of the detector depends crucially on the geometrical and optical fibre parameters and, in particular, on their possible degradation due to ionizing radiation. The dearth of results for this fibre type in the total ionizing dose range of the upgrade, 60 Gy up to 35 kGy, along with conflicting conclusions regarding annealing and dose rate behaviour in literature, required a set of irradiation campaigns to estimate the behaviour of the full detector over its lifetime, especially as it is non-linear with dose. We will present results from the irradiation experiments performed by the LHCb SciFi collaboration over the last two years which show a behaviour due to radiation damage consistent with published models for polystyrene-based fibres, and are able to reproduce these results in various test facilities and beams. Other measurements of the fibre properties will be shown as well.

Abstract content Silicon Photomultipliers (SiPMs) are a promising candidate for replacing conventional photomultiplier tubes in many applications, thanks to ongoing developments and advances in their technology. A drawback of conventional SiPMs is their limited fill factor caused by the need for a high ohmic polysilicon quench resistor and its metal lines on the surface of the devices, which in turn limits the maximum photon detection efficiency. At the Semiconductor Laboratory of the Max-Planck Society (HLL) a novel detector concept was developed integrating the quench resistor directly into the silicon bulk of the device resulting in a free entrance window on the surface. The feasibility of the concept was already confirmed by simulation and extensive studies of first prototype productions. Recently SiPMs were also considered as an attractive alternative for tracking applications in vertex detectors. The requirements for a fast response, simple design and high fill factor can all be met by SiPMs. In addition the increased trigger probability for an avalanche by minimum ionizing particles allows device operations at lower overbias voltages, resulting in a decreased noise contribution. The concept can be evolved further towards an imaging photo-detector. A new design for an application of these SiPM devices as vertex detectors with active quenching developed by the HLL and DESY as well as first simulation results will be presented. Also, first measurements of the trigger efficiency as a function of the applied overbias voltage of SiPM devices will be shown.

The Geiger-mode operation of a SiPM requires a high-ohmic quench resistor, which is usually realized in conventional devices by a structured polysilicon layer on the surface, leading to a decrease of the maximum photon detection efficiency (PDE). In order to improve on this drawback, the Semiconductor Laboratory (HLL) of the Max-Planck-Society has developed a novel detector concept with the quench resistor integrated into a high-ohmic silicon bulk. This in turn results in a free and unstructured entrance window for photons on the surface of the device. In a first prototype production the proof of concept of this novel approach was confirmed and additional prototypes for devices improvements were developed. A brief general overview of our novel SiPM approach as well as its advantages and disadvantages will be discussed. In addition, the latest results of the characterization of SiMPl devices, including the PDE, optical cross talk and recovery time as well as an outlook for further improvements in the device performance will be presented.

The tracker system will have a major overhaul. Its components will be replaced with new technologies in order to cope with the increased hit occupancy and radiation environment. A detector made of scintillating fibres read out by silicon photomultipliers (SiPM) is studied for this upgrade. Even if this technology has proven to achieve high efficiency and spatial resolution, its integration within a LHC experiment bears new challenges. This detector will consist of 12 planes of 5 to 6 layers of 250um fibres with an area of 5x6m2. Its lead to a total of 500k SiPM channels which need to will be read out at 40MHz. This talk gives an overview of the R&D status of the readout board and the PACIFIC chip. The readout board is connected to the SiPM on one side and to the experiment data-acquisition, experimental control system and services on the otherside . The PACIFIC chip is a 128 channel ASIC which can be connected to one 128-channel SiPM without the need for any external component. It includes the analog signal processing and a 2 bits non-linear flash ADC for digitisation. The PACIFIC chip design highlights a very fast shaping (~10ns) and the ability to cope with different SiPM suppliers with a power consumption below 8mW per channel.
