These cost-effective GRPC stand high particle rate. The excellent timing they can provide could allow to improve on the trigger rate and reduce the pileup consequences of the LHC luminosity increase. Single and multi-gap GRPC using low-resistivity glass are being proposed to equip high eta region of experiments such CMS. Electronics readout with a time measurment precison of less than 25 ps is being developped to equip such detectors. Summary With the increase of the LHC luminosity foreseen in the coming years many detectors currently used in the different LHC experiments will be dramatically impacted and some need to be replaced. The new ones should be capable not only to support the high particle rate but also to provide excellent timing to reduce the data ambiguity due to the expected high pileup. RPC using low-resistivity glass are proposed to equip the very forward region of the LHC experiments. In their single-gap version they can stand rates of few kHz/cm2. Their time precision of about 1ns could in principle allow to reduce the noise contribution, leading to an improvement of the trigger rate. In their multi-gap version they can do better in both the particle rate detection and the time precision measurement. Time precision of less 25 ps could be obtained. This aims at reducing the ambiguity the high expected pileup will introduce. In both cases new electronics equipped with excellent timing precision measurement are being developed to read out the RPC detectors. Tests are ongoing to validate the different scenarios.

[Tipp2014] Questions re: TIPP2014 Abstract Submission
by Hassan Chagani 27 Jan '14

27 Jan '14

Dear Sir/Madam, I would like to submit an abstract for TIPP 2014, but had a few questions regarding the abstract submission form. I did try to search for the answers before writing this email, but to no avail. Hopefully, answering my questions will not take up too much of your time. 1. There is a field titled 'Summary'. Although it is not a mandatory field, I am not sure of what should be written there as the abstract seems to fit better in the 'Abstract content' field. What is the purpose behind the 'Summary' field? 2. It is not possible to specify the 'Presentation type'. Is this deliberate? Will there be any poster sessions, or will the conference only consist of talks? 3. What is the difference between a 'Primary Author' and 'Co-Author'? I assume that the former can change the abstract, but the latter cannot. Is this correct, and is this the only difference? Sorry if all of these questions have already been answered on your website and I simply haven't been able to find the answers. Thank you in advance for your help. Yours Faithfully, Hassan Chagani. Tate Laboratory of Physics 116 Church Street SE University of Minnesota Minneapolis MN 55455 USA

The data were analysed using an electrical model of the SiPM which allowed determining characteristic parameters like pixel capacitance, quench resistor and quench capacitance, parasitic resistance, and breakdown voltage in different ways, and studying their dependence on X-ray dose. In addition, the doping profile and the electric field distribution in the SiPM have been determined. It is found that the electrical model provides a consistent description of the data. The main changes with X-ray dose are a decrease of the parasitic resistance, and an increase in dark current due to current generation at the Si-SiO2 interface. Whereas for dose values of 20 kGy and below the surface generation current hardly affects the properties of the SiPM above the breakdown voltage, it gets amplified for dose values above 20 kGy resulting in a significant increase in dark-count rate. Apart from this effect, the performance of the Hamamatsu SiPM as high-gain photo detector is hardly affected by X-ray radiation up to a of 20 MGy. Summary Hamamatsu Silicon Photo Multipliers (SiPM) of the type S10362-11-050P are characterized and the change of their parameters after irradiation to X-rays of 200 Gy, 20 kGy, 2 MGy and 20 MGy determined. A novel method how characteristic parameters of SiPMs can be obtained in different ways is presented. Primary Authors: Prof. KLANNER, Robert (Univ.

Meanwhile, full CMOS integration in the pixel is achievable due to the availability of deep P-well. Therefore, a novel concept of pixel with integrated discriminator was realized to develop a fast and power efficient rolling shutter CPS architecture for the ALICE-ITS upgrade. Compared with the conventional CPS using column-level discrimination, the in-pixel discrimination sets the analog processing within the pixel. Thus the analog buffer driving the long distance column bus is no longer needed and the static current consumption per pixel can be largely reduced from 120µA down to 15µA. Besides, the row processing time can be halved down to 100ns thanks to small local parasitic. As a proof of concept, the prototype chip called AROM0 was fabricated in April 2013. Full functionality and the noise performance of the chip have been validated in laboratory test. Based on the experience of AROM0, the improved pixel designs have been implemented in the chip called AROM1 which is an intermediate prototype chip anticipating the final sensor architecture proposed for the ALICE-ITS upgrade. It features the pixel array of 64 × 64 with double-row readout while integrating the on-chip biasing/reference control and JTAG programmable sequence management circuitry. This paper will present the design and test results of AROM0. It’ll also discuss the improvement in AROM1 and present the test results of this sensor which is expected in early 2014.

This detector is being developed by the network NEWs, which includes several applications. We can name between many others Dark Matter searches, low level radon and neutron counting or low energy neutrino detection from supernovas or nuclear reactors via neutrino-nucleus elastic scattering. In this context, this works will present the characterization of a spherical detector of 1 meter diameter using two argon-based mixtures (with methane and isobutane) and for gas pressures between 50 and 1500 mbar. In each case, the energy resolution shows its best value in a wide range of gains, limited by the ballistic effect at low gains and by feedback at high gains. Moreover, the best energy resolution shows a degradation with pressure. These two effects will be discussed in terms of gas avalanche properties. Finally, the effect of an electrical field corrector in the homogeneity of the gain and the energy threshold measured in our setup will be also discussed.

The Mini-balloon filled with 136Xe loaded liquid scintillator was installed in the KamLAND detector. From the first result of KamLAND-Zen, there was the BG peak at 2.6 MeV region. As a result of data analysis, it was found that 110mAg was the BG candidate. The purification system of xenon and liquid scintillator were developed to remove the 110mAg BG. 136Xe gas was collected from the liquid scintillator in the Mini-balloon to purify 136Xe gas and liquid scintillator, respectively. In addition, 136Xe gas was purified using SASE getter just before dissolving 136Xe into liquid scintillator. The 2nd phase of KamLAND-Zen was started in 2013. I will report the status of KamLAND-Zen and purification methods.

For this purpose we design and test a massively parallel pattern-recognition algorithm, inspired by studies of the processing of visual images by the brain as it happens in nature. We find that high-quality tracking in large detectors is possible with sub-microsecond latencies if the algorithm is implemented in modern, high-speed, high-bandwidth FPGA devices.

To get the stable working time, lower discharge rate with long working term and higher effective gain, the new structure detector has been designed. One structure was based the coated Ge resistive anode readout with bulk Micromegas detector, and the other structure was combined with the detection’s advantages of Micromegas and gas electron multiplier (GEM), which was composed of a Micromagas chamber with one GEM foil as preamplifier. In this paper, the two structures of the detectors and detection principles were presented in details. Using a 55Fe X-ray radioactive source in the operation mixtures gas of argon and isobutene (Ar/Iso=95/5), the performances of the detector gain, discharge rate, energy resolution and stable working time are investigated. A further measurement in the four operation mixtures gas has been accomplished at 1W1B laboratory of Beijing Synchrotron Radiation Source. In the experiment, the energy range of X-ray was set from 6 keV to 20 keV and the setting step was 1 keV. Finally, the data of beam test were obtained and analyzed. The preliminary results show that a stable working time could reach more than 30 hours of continuous work, the gain of the detector could exceed 10^6 and the discharge rate could be reduced by nearly 100 times at the same gain.

Materials of different densities can be differentiated using this technique as muons interacting with high-Z materials are scattered to a greater degree by multiple Coulomb scattering than low-Z materials. This scattering is determined experimentally by detecting the incoming and outgoing trajectory of the muon as it enters and exits the inspection volume. This technique is particularly useful for visualising volumes that are difficult to inspect visually. AWE is primarily interested in investigating the use of MST for scanning cargo containers, as it could be used for the detection the presence of radiological material without introducing an artificial radiation source. AWE is currently testing and developing two MST experimental systems based on drift chamber technology. One of the experiments is constructed using six layers of three adjacent drift chambers positioned above and below an inspection volume. The second system is a similar configuration and is constructed of drift tubes. The technical challenges of producing the experimental system with a resolution capable of accurately determining the muon scattering angle within a few milliradians will be detailed and the experimental results obtained compared with Monte Carlo models.
