We studied several samples of focusing aerogel using multichannel SiPM photodetectors with a high po sition resolution. One of photodetectors was based on novel digital SiPM t echnology - Digital Photon Counter produced by Philips. Particle track was measured by gaseous strip detectors based on GEMs that have 70 μm resolu tion. That allowed us to precisely measure the radius distribution of Cher enkov photons from aerogel and compare with a prediction based on aerogel refractive index profile obtained by a digital radiography.\nIn 2012\, the first aerogel blocks with a continuous density gradient along thickness w ere produced. This technology can dramatically reduce the contribution fro m the radiator thickness to the resolution of the measured Cherenkov angle in the FARICH detector. A special automatic setup was used to control rea gents ratio during the synthesis process. The first few samples were teste d using a digital radiography and the electron beam.\n\nhttps://indico.inp .nsk.su/event/0/contributions/21/ LOCATION: URL:https://indico.inp.nsk.su/event/0/contributions/21/ END:VEVENT BEGIN:VEVENT SUMMARY:Threshold aerogel Cherenkov counters of the KEDR detector DTSTART;VALUE=DATE-TIME:20140226T053000Z DTEND;VALUE=DATE-TIME:20140226T055000Z DTSTAMP;VALUE=DATE-TIME:20260417T093431Z UID:indico-contribution-3-22@indico.inp.nsk.su DESCRIPTION:Speakers: Alexander Barnyakov (Budker Institute of Nuclear Phy sics)\nParticle identification system based on aerogel threshold Cherenkov counters ASHIPH (Aerogel SHifter PHotomultiplier) was installed in the KE DR detector in 2013.

It has been developed for p article identification in the barrel region of the Belle II spectrometer\, which will probe new physics beyond the Standard Model with a luminosity of 8x10³⁵/cm²/s. The TOP detector is intended to achieve good π/K sep aration in the momentum range up to around 3 GeV/c under the high-luminosi ty environment.\nThe detector construction has been started and the remain ing development is being finalized toward the installation into the spectr ometer in early 2015.\nA single detector module mainly consists of a synth etic silica plate\, as the Cherenkov radiator\, and an array of micro-chan nel plate (MCP) photomultiplier tubes (PMTs) with readout electronics. Opt ical components for the first detector module are being delivered one afte r another. The delivered components are in process of optical inspections and assembly preparation. Mass production of the MCP-PMTs is on going smoo thly. The performance details are being inspected under the operational ma gnetic field of 1.5 T. Although the lifetime of an MCP-PMT has been an iss ue concerning the high-luminosity environment\, atomic layer deposition on MCPs has improved the lifetime significantly. Development of the readout electronics is being finalized. Their high-speed waveform sampling ASICs a nd circuit board stacks are in preproduction. Preproduction for the mechan ical structure of a detector module is about to start. It is crucial to es tablish the optical and electrical contacts between the optics\, MCP-PMTs and readout electronics. A beam test on a detector module prototype has be en carried out using a 2 GeV/c e⁺ beam at the LEPS beam line of SPring-8 in June 2013. The\nprototype consists of the optics and MCP-PMTs that hav e nearly final and final specifications\, respectively. The test results h ave demonstrated the detector principle reasonably.\n\nhttps://indico.inp. nsk.su/event/0/contributions/50/ LOCATION: URL:https://indico.inp.nsk.su/event/0/contributions/50/ END:VEVENT BEGIN:VEVENT SUMMARY:Long term experience and performance of COMPASS RICH-1 DTSTART;VALUE=DATE-TIME:20140226T050500Z DTEND;VALUE=DATE-TIME:20140226T053000Z DTSTAMP;VALUE=DATE-TIME:20260417T093431Z UID:indico-contribution-3-51@indico.inp.nsk.su DESCRIPTION:Speakers: Fulvio Tessarotto (INFN - Trieste)\nThe RICH-1 Detec tor of the COMPASS Experiment at CERN SPS provides high quality hadron ide ntification in the particle momentum range from 3 to 60 GeV/c\, covering a wide angular acceptance and operating at high rates.\nIt is in operation since 2002 and its performance increased thanks to progressive optimizatio n and to a major upgrade of its photon detection system\, implemented in 2 006\; a new upgrade is foreseen for 2016\, using MPGD-based photon detecto rs.\nThe main characteristics of COMPASS RICH-1 and the most critical prob lems encountered and presently faced are discussed together with the adopt ed solutions to guarantee radiator gas purity\, mirror alignment control\, stable photon detector response\, heat removal and readout electronics op timization.\nThe PID performance is presented and the observed evolution o f the effective quantum efficiency of CsI photocathodes in gas photon dete ctors is discussed.\nThe motivation and the plan for the future upgrade ar e briefly mentioned.\n\nhttps://indico.inp.nsk.su/event/0/contributions/51 / LOCATION: URL:https://indico.inp.nsk.su/event/0/contributions/51/ END:VEVENT BEGIN:VEVENT SUMMARY:ARICH for Belle II DTSTART;VALUE=DATE-TIME:20140226T074000Z DTEND;VALUE=DATE-TIME:20140226T080500Z DTSTAMP;VALUE=DATE-TIME:20260417T093431Z UID:indico-contribution-3-52@indico.inp.nsk.su DESCRIPTION:Speakers: Yosuke Yusa (Niigata University)\nWe will present ov erview of Aerogel Ring Imaging Cherenkov counter (ARICH) which is develope d as a particle identification detector in next generation B-factory exper iment\, the Belle II.
