These links provide not only a good electrical isolation, but also a bidirectional centralized data collection and command distribution. Further more the capacity of the gigabit fiber is far more than be needed, which stimulated us a idea to share the high speed data link with the slow control function(detector parameters setting). In addition to the description of belle2link in TIPP2011, this talk describes in detail about the relization of this slow control, including parameter setting in frontend electronics, combining slow control data in FE part with and separating slow control data in BE part from detector physics data, data priority management, single command mode and batch commands mode implementation. Tests made with drift chamber and silicon vertex detector systems are provided together with results and discussions. Summary The Belle2link, an unified overall readout with optical high speed data transmission shared with slow control functionality of detector parameter control has been designed for the Belle II experiment at KEK, Japan. A model system based on drift chamber system was successful and tt has been accepted by the collaboration. System for Drift Chamber had passed with cosmic ray test and beam test, system for Silicon Virtex Detector is now under beam test at DESY, Germany which showed also a success. Implementation and tests to other systems are under going.

The measurements were performed over a period of several weeks, during which a number of operating conditions were varied. The sensors were fabricated by Hamamatsu on 200 µm thick float-zone silicon. Their pitch is 80 µm, and both p-stop and p-spray isolation of the p+n strips were studied. The electrons from the 90Sr source were collimated to a spot with a full-width-at-half maximum of 1.8 mm at the sensor and the dose rate at the maximum in the SiO2 was about 0.6 mGy/s. The estimated dose at the end of the measurements was about 1 kGy in SiO2. In addition, test structures (pad diodes, MOS capacitors with and without p-stop and p-spray implants, and gate-controlled diodes) fabricated together with the sensors, were investigated for X-ray doses of up to 1 kGy in SiO2 in order to determine technological parameters and their dependencies on X-ray dose. As function of irradiation time with the 90Sr source significant changes in charge collection and charge sharing are observed. Annealing studies with temperatures up to 80°C have shown that the observed changes are only partially reversed. The observations are qualitatively explained with the help of TCAD simulations. The relevance of the measurements for the design and the use of p+n strip sensors in different radiation environments are discussed.

The signature is a non-zero transverse polarization (P_T) of muons in the direction perpendicular to the decay plane. Using the same process the E246 experiment at KEK has set an upper limit on | P_T | < 0.0050 at the 90% confidence level. TREK is an upgrade of E246 with the goal of achieving more than a factor of 20 higher sensitivity using high intensity Kaon beam from J-PARC and the detector with major upgrades that include a new GEM tracker, new photon device for the CsI(Tl) calorimeter and a new magnet system providing uniform field. The most important element of TREK is the new muon polarimeter of novel design, incorporating an active muon stopper instrumented by an array of drift tubes for tracking. This design allows the tracks of muons and positrons to be reconstructed, providing a large acceptance for positrons with higher analyzing power, background suppression, and handles for controlling systematic uncertainties such as those arising from uncertainty on the decay position and its distribution. We present an overview of the TREK experiment and detail of the muon polarimeter R&D with results of studies using Monte Carlo simulation and beam tests of the full size prototype.

Micopattern Gaseous Detector (MPGD) technologies opened new ways to photon detection, where the possibility for reduced ion feedback, better timing and the suppression of non-photon signals are factors of improved performance. On the other hand the microstructure of an MPGD renders the photo-electron emission, transfer and subsequent detection to be a very complex process. We have developed a high resolution UV photon scanner, where single photon-electron response measures local detection efficiency and gas gain with position resolution better than 100 microns. Studies on Thick GEM based photon detectors proved the existence of inefficient symmetry points, and shed light on hole-gain structure and microscale variance. In fact practically all MPGD detectors, even if not designed for photon detection in the first place, can be made sensitive, and thus be explored, by the scanning system. Measurement of the microsturcture of the charge transport can lead to a better understanding of the detection mechanisms, and help in optimization of various MPGD, especially for Cherenkov detectors. The presentaion will focus on details of the critical parts of such a system; and recent results on TGEM microstructure with its dependence on the applied micropattern configurations.

The SCT is constructed of 4088 silicon detector modules. We find 99% of the 6.3 million strips are operational, the noise occupancy and hit efficiency exceed the design specifications; the alignment is very close to the ideal to allow on-line track reconstruction and invariant mass determination. We will report on the operation and performance of the detector including an overview of the issues encountered. We observe a significant increase in leakage currents from bulk damage due to non-ionizing radiation which is in agreement with the predictions.We will also cover the time evolution of the key parameters of the strip tracker, including the evolution of noise and gain, the measurement of the Lorentz angle and the tracking efficiency in the harsh LHC environment. Valuable lessons for future silicon strip detector projects will be presented. Summary We propose a talk that summarizes the data-taking operations of the ATLAS Semi Conductor Tracker at the LHC, including the main difficulties we had to cope to, namely the failure of the optical transmitter on the readout board and the higher current of a subset of sensors. We have an updated determination of the radiation damage and we can show the performance of the SCT during tha LHC Run-1. The activities during the shutdown consist mostly in increasing the number of readout boards, to cope with a higher trigger rate.

Cherwell is a 4-T CMOS sensor in 180 nm technology on a 12um epitaxial substrate with low-noise, low-power, in-pixel correlated double sampling, and high conversion gain. Cherwell 1 consists of four arrays, two optimized for vertexing and tracking applications, and two for digital calorimetry applications. The vertexing arrangements have a matrix of 96x48 pixels with a pitch of 25 um. The “reference array” is readout on a rolling shutter base with a fine resolution 12-bit, single-slope column parallel ADC. The “strixel" array has the readout and ADC circuits embedded in the space between the pixel diodes. The two sections for calorimetry have a matrix of 96x48 pixels with 25 um pitch and 48x24 pixels with 50 um pitch, respectively. Additional circuitry is added to provide charge summing of 2x2 pixels during readout. Cherwell 2 is a prototype candidate sensor to be used in the upgrade of the ALICE Inner Tracker System at the LHC. It has three variants of a 128x128 pixel array on a 20um pitch using the strixel technology. We report on the characterisation and performance of the prototypes, on the test bench and at the test beam. Summary Performance of two prototype CMOS MAPS sensors.

The photon energy spectrum from the neutrino radiative decays is expected to have a sharp edge at high energy end in a far-infrared region ranging from 14meV to 25meV (from 50um to 90um in wavelength). We explore the the cosmic infrared background photon energy spectrum in this region for feeble contribution from neutrino decays. Thus, the detector is required to measure photon-by-photon energies with high resolution enough to identify the edge structure, and designed for a rocket or satellite experiment. One of our choices for the detector is STJ using hafnium (Hf-STJ) which is expected to have 2% energy resolution for single photon of 25meV due to very small gap energy of hafnium. Another choice for the detector is a combination of the diffraction grating and array of niobium-aluminum STJ (Nb/Al-STJ) pixels, where each Nb/Al-STJ pixel is capable of single photon detection for a far-infrared photon delivered to each pixel according to its wavelength by the grating. For the Hf-STJ development, we have successfully produced a superconducting-insulator-superconducting structure using hafnium, that is confirmed by Josephson current, and observed a response to visible light illumination, although much higher leak current than its requirement is a major issue to be resolved. For the Nb/Al-STJ, it is also challenging that an amplifier at extremely low noise level of 10 electron-equivalent-noise is required.

In recent years, R&D has been mainly active to improve the sensitivity required for polarimetry. In this context, a concept of a Time Projection Chamber (TPC) was proposed as an active target and pair production imager with a high angular resolution and background reduction capabilities. After introducing the HARPO TPC and its potential as gamma-ray telescope, we will present the characterization of the TPC readout plane which provides gas electron amplication within a microstructure composed of the association of a Micromegas and Gas Electron Multiplier. Recent results using cosmic-ray events will be shown and nally the beam test, scheduled this year, with polarized photon at MeV energy will be discussed. Summary D. Bernard, P. Bruel, M. Frotin, Y.

Summary Proposing a new cooling system for the the Upgrade of the UT Tracker for LHCb, emerged a design with a zig-zagging routing for the CO2 evaporative cooling. This is needed to satisfy the power dissipation extraction requirements dictadìted by the use of powerful read-out chips. The strip tracker detector silicon sensors need to be maintained at operating temperature of -5 °C, the genrated thermal power is about 3800 W. The investigated solution looks at two stave design: one using straight pipes embedded in carbon foam and making use of high conductivity TPG inserts put trought the insulation layers to improve the thermal performance; the other, more efficient solution from the thermal point of view, envisages a "snake" cooling pipe embedded in carbon foam, passing underneath the chip concentrated power sources in a very effective way.
