The new sub-detector, named Insertable B-layer (IBL), will be installed between the existing Pixel Detector and a new smaller radius beam-pipe at a radius of 3.3 cm. To cope with the high radiation and pixel occupancy due to the proximity to the interaction point, a new read-out chip and two different silicon sensor technologies (planar and 3D) have been developed. Furthermore, the physics performance will be improved through the reduction of pixel size while targeting for a low material budget should be imposed, pushing for a new mechanical support using lightweight staves and a CO2 based cooling system. An overview of the IBL project as well as the present experience in its construction will be presented, focusing on the staves production, qualification of the assembly procedure, integration of the staves around the beam pipe and commissioning of the detector.

For the PID system in the forward region of the spectrometer, a proximity focusing RICH counter with aerogel radiator is being developed. For this counter we have devised a focusing radiator consisting of two aerogel layers with increasing refractive index along the particle path, which results in a focusing of Cherenkov light at the photon detector plane. In this way, a thicker radiator can be used, and the number of photons can be increased without degrading the single photon Cherenkov angle resolution. The detector will provide a $4~\sigma$ separation of pions and kaons up to momenta of 4 GeV/c, at the kinematic limits of the experiment. The main challenge was, however, a reliable multichannel sensor for single photons that operates in the high magnetic field of the spectrometer (1.5 T) and withstands the radiation levels expected in the experiment. A 144-channel Hybrid Avalanche Photo-Detector (HAPD) was developed in a collaboration with Hamamatsu Photonics K.K. The design of the detector components is currently being finalized and part of the mass production has already started. The counter will be ready for installation in 2015. We will report on the tests of the prototypes conducted with test beams at CERN and DESY, and the optimization and performance studies of the counter final design, based on the Geant4 simulation.

We used a 1 liter PTFE chamber observed by an array of 7 large area SiPMs (Hamamatsu S11828-3344M) covering about the 4% of the internal surface. The chamber is lined with a reflective foil (VIKUITI) evaporated with a wavelength shifter (TetraPhenyl Butadiene). This solution allows to convert the UV photons to the visible band, thus matching the SiPM sensitivity window while maximizing light collection. The measured light-yield is comparable with the highest light-yield values obtained in similar conditions using standard 3" cryogenic PMT's (Hamamatsu R11065) for a 3 times higher photo-cathodic coverage. The present result, combined with the other well known intrinsic SiPM advantages (compact design, contained costs, low bias voltage,… ) represents a step forward in the confirmation of the SiPM technology as a real alternative to standard PMT-based read-out systems for application in cryogenic noble liquid detectors.

See below a detailed summary of your submitted abstract: Conference: Tipp 2014 - Third International Conference on Technology and Instrumentation in Particle Physics Submitted by: ARAUJO, Henrique Submitted on: 26 February 2014 11:00 Title: The LZ dark matter search Abstract content The LUX-ZEPLIN (LZ) experiment is a next-generation search for Weakly Interacting Massive Particles, scaling the very successful double-phase xenon technology to multi-tonne target mass. LZ will be deployed at the 4850-ft level of the Sanford Underground Research Facility (South Dakota, USA) after completion of LUX, which is presently operating there. At its core, LZ will feature a 7-tonne (active) liquid xenon TPC surrounded by two ‘veto’ detectors. Particle interactions in the WIMP target generate two signatures: prompt scintillation light and ionisation charge, the latter transduced to a pulse of electroluminescence light in a thin gaseous layer above the liquid. Our strategy is to mitigate radiogenic backgrounds from detector materials through a combination of self-shielding, precise vertex location, coincidence vetoing, and xenon purification – to expose a uniform background from astrophysical neutrinos. Electron recoils from solar pp neutrino scattering can be mostly discriminated by the ratio of the two signatures, which differs from that for nuclear recoil interactions expected from WIMPs. We present the project status and the sensitivity reach of this exciting instrument due to start construction soon.

A $^{96}$Zr nuclei has a large Q-value (3.35MeV), and no experiment is planned to use as a target. In order to realize ton scale target isotope with good energy resolution (4\%(a)2.5MeV), we have used zirconium beta-diketon complex which has huge solubility (over 10w.t.\%) to the Anisole. However, the absorption wavelength of diketon ligand overlaps with the luminescence from Anisole. Therefore, the light yield of liquid scintillator decreased in proportion to the concentration of beta-diketon complex. In order to avoid this problem, we synthesized beta-keto ester complex introducing -OC3H7 or -OC2H5 substituent groups in the beta-diketon complex. These complexes have shorter absorption wavelength (245nm) than the emission wavelength of Anisole (275nm). The scintillation light yield recoverd about double, however, did not reach at the expected value, because the residual absorption around the 275nm still exists. We found those were caused by the imprities of beta-keto ester complex and it will be solved by thr purifying the complex. Now we have also found that a diethyl malonate ligands shifted the absorption peak to around 210nm, and the complex will have no quenching for the Anisole based liquid scintillator. Here we will report the present status.

In soft X-ray imaging for mammography, most of X-ray Energy is absorbed a surface of scientillator. Thus, MTF and sensitivity of image sensor can be decreased. In our study, we adapted a upside-down structure, which has bottom sided scientillator of image sensor. In MCNP and LightTools simulation, light output and spatial resolution is increased more than 15%. The test is being set in our places and finished before the conference. The test chip have been fabricated in 0.18um 1P3M process.

The increase in luminosity will produce a higher particle background with respect to present conditions. Performance and stability of detectors at LHC and future upgrade systems will remain the subject of extensive studies. The current CERN-Gamma Irradiation Facility (GIF) has been intensively used to simultaneously expose detectors to the photons from a 137Cesium source and to high energy particles from the X5 beam line in SPS West Area for many years. From 2004 onwards, only the 137Cesium source is available for irradiations and the shutdown of the present facility is scheduled for the end of 2014. The present contribution describes a joint project between CERN-EN and CERN-PH departments to design and build the new CERN GIF++ facility. GIF++ will be a unique place where high energy charged particle beams (mainly muon beam with momentum up to 100 GeV/c) are combined with a 14 TBq 137Cesium source. The higher source activity will produce a background gamma field which is a factor 30 more intense than that at GIF, allowing to cumulate doses equivalent to HL-LHC experimental conditions in a reasonable time. The 100 m2 GIF++ irradiation bunker has two independent irradiation zones making it possible to test real size detectors, of up to several m2, as well as a broad range of smaller prototype detectors and electronic components. The photon flux of each irradiation zone will be tuned using a set of Lead filters with attenuation factors from zero to 50000. Flexible services and infrastructure including electronic racks, gas systems, radiation and environmental monitoring systems, and ample preparation zone will allow time effective installation of detectors. A dedicated control system will provide the overview of the status of the facility and archive relevant information. The collaboration between CERN and the users’ detector community, the latter providing detector specific infrastructures within the framework of the FP7 AIDA project, will bring the new facility to operation by the end of 2014.

The heart of HEC read-out electronics is the pre-amplifier and summing (PAS) system, which is realized in GaAs ASIC technology. These PAS devices are installed inside the LAr cryostats, directly on the detector. They have been proven to operate reliably in LHC conditions up to an integrated luminosity of 1000 fb$^{-1}$, including safety factors. However, at the HL-LHC a total integrated luminosity of 3000 fb$^{-1}$ is expected, which corresponds to an increase of a factor of 3-5 in the expected radiation levels. On top of this, a safety factor of at least 2 needs to be accounted for to reflect our confidence in the background rate simulations. Samples of the GaAs ASIC have therefore been exposed to neutron and proton radiation with integrated fluences in excess of 4x10$^{15}$ n/cm$^2$ and 2.6x10$^{14}$ p/cm$^2$, several times the levels expected for ten years of HL-LHC running. In-situ measurements of S-parameters allow the evaluation of frequency-dependent performance parameters, like gain and input impedance. The non-linearity of the ASIC response has been measured both at warm and at cold, i.e. at LAr temperatures. This allows an improved estimation of the expected degradation of the HEC performance. The measured gain and non-linearity of the ASIC response have been applied to Monte-Carlo simulations in order to understand their effects on jet measurements in HL-LHC conditions.

The working principle is inspired from neurobiology, in particular by the processing of visual images by the brain as it happens in nature. It is based on extensive parallelization of data distribution and pattern recognition. In this work we report on the design of a practical device that consist of a telescope based on single-sided silicon detectors; we describe the data acquisition system and the implementation of the track finding algorithms using available digital logic of commercial FPGA devices.
