We are aiming for a sensitivity of one in $10^{16}$ $\mu$-decays. To measure the momentum and vertex position of low momentum electrons (10 - 53 MeV/c) originating from such a rare decay with high precision, a tracking detector built from High-Voltage Monolithic Active Pixel Sensors (HV-MAPS) is implemented. The MUPIX chips are HV-MAPS designed for Mu3e and are implemented in 180 nm HV-CMOS technology. HV-MAPS is the technology of choice because it can be thinned to 50~$\mu$m, is radiation-tolerant, has a high time resolution, and is low cost. Furthermore, the pixel electronics are embedded inside the sensor chip to reduce the material budget. Performance results of the MUPIX4 chip are presented. In 2013, we tested the MUPIX4 chip using a 1 - 6~GeV electron beam at DESY. The discussed results include the spatial resolution, time resolution, and efficiency of the MUPIX4 chip.

by Adi Bornheim 23 Jan '14

23 Jan '14

Dear TIPP organisers, I am in charge of coordinating conference submission on behalf of the CMS ECAL collaboration. I was wondering if it is mandatory to specify the speakers name at submission time or can we submit on behalf of the collaboration in case we have not decided on the individual presenting ? Kind regards, Adi Bornheim

The development of two novel detectors is required, a PET head extension for a commercial US endoscope placed close to the region of interest (ROI) and a PET plate over the patient’s abdomen in coincidence with the PET head. Technological challenges include: 1 mm image spatial resolution (SR), an unprecedented 200ps Coincidence Time Resolution (CTR) for enhanced background rejection, online tracking of both detectors and image reconstruction of images with partial volume information from an asymmetric geometry. The paper will present results achieved with the first prototype components of the EndoTOFPET-US detector. Characterization of 4096 LYSO crystals glued to 256 Hammamatsu MPPC matrices of 4x4 photo-detectors each, performance tests of two candidate ASIC chips for fast TOF readout, and performance studies of the digital silicon-photomultiplier detector for the endoscopic probe will be presented. The first system integration measurements will be shown, which demonstrate that the requirements in terms of SR and CTR are at reach.

Under the umbrella of the KACST Detector Laboratory (KDL) project we have succeeded in designing, constructing and, operating a single channel small (10x10 cm2 ) GEM detector for radiation detection applications. The performances of the detector was tested using two mixture of gases; Ar-CO2 (80:20) mixture and He-CO2 (80:20) using five γ-rays sources with energy range from 64.5 to 662 keV. In addition, one α-particle source with energy of 5.48 MeV was used. In this paper the technical aspects of this detector will be briefly discussed. The experimental procedures and the obtained results will be given. Future work and further improvements to the performances of the detector in several applications will be outlined.

Many of the properties of solid xenon have been measured previously employing small volumes and thin films. Two major R\&D issues must be addressed to make a solid xenon particle detector; the demonstration of the scalability of solid xenon and the capability to readout scintillation lights and ionization signals from the solid xenon. Both issues are being addressed with a dedicated cryogenic system at Fermilab. In this talk, we will report the recent results of the solid xenon detector R&D.

The Zero Ion Backflow electron multiplier operates in a noble gas atmosphere and supress the ion backflow to the level of the primary ionization, totally blocking the secondary ions that are produced in the multiplier. This detector is composed by a proportional scintillation region, composed by two highly transparent meshes, followed by a gaseous photon-multiplier. The primary electrons drift through the proportional scintillation region under the influence of an electric field below the ionization threshold of the gas, emitting electroluminescence without the production of secondary ions. The electroluminescence signals are collected by the gaseous photon multiplier, composed by a gaseous electron multiplier coupled to a CsI phothocade, and further amplified by electron avalanche. The positive ions that result from electron avalanches in the gaseous photomultiplier are prevented from reaching the conversion region by an electrostatic separation between the proportional scintillation region and the gaseous photomultiplier. The ion back flow is therefore reduced to the level of the primary ionization and is totally independent on the electron avalanches that occur on the gaseous photomultiplier. Summary We present the results obtained with the Zero Ion Backflow electron multiplier operated in pure Xenon equipped with a proportional scintillation region of 6 mm. The gaseous photomultiplier is composed by a double GEM cascade coupled to a CsI photocathode, separated from the proportional scintillation region by an extraction region with 2 mm. The transference of the secondary ions from the gaseous photomultiplier to the proportional scintillation region is dependent on the electric field between these two regions, EExtraction, that also influences the photoelectron extraction from the CsI photocathode. We have determined the influence of this field on the levels of ion backflow and on the photo-electron extraction. A value between 0.1 and 0.2 kV/cm*bar was found to ensure simultaneously maximum relative photoelectron extraction and full ion backflow suppression. Energy resolution of 17% was measured when irradiating the detector with 5.9 keV x-rays.

The loss is mainly due to a proton which is produced due to double electron stripping of the H^- beam by the residual gas inside the beam pipe, and the titanium beam pipe. We have developed a detector system consisting of 8 planes of scintillating fiber hodoscopes in order to measure proton tracks emitted from the beam pipe of the J-PARC linac. The system measures positions of the charged particle tracks in a small solid angle, and also measures the time-of-flight of each particle. We show angular and energy distribututions of the proton tracks measured in 2012-2013. We also show comparison of the results with simulation.

The TPC consists of an octagonal-shape drift cage of 50 cm diameter and 55 cm height, filled with Ar-CH_4 (90:10) gas, and the end cap chamber consisting of a gating grid plane, 3-layer GEMs, and a pad plane. The TPC is operated in a dipole magnetic field of 1 T in parallel to the drift electric field. The horizontal position resolution is expected better than 300 um. We have build a small-scale prototype TPC and performed a beam test. The position shift due to positive-ion feedback was suppressed within ±0.2 mm both in transverse and longitudinal directions at the beam rate up to 5 × 105 cps/cm2. Detection efficiency of 97 % per pad row at a low rate (103 cps/cm2) beam, and 90 % at a high rate (106 cps/cm2) beam were achieved. We also performed a laser test of the prototype in magnetic field. We observed a reasonable improvement of the position resolution due to the magnetic field. We also show the status of the test of the end cap chamber of the full-size TPC.
