Poster session of the group B
The proximity-focusing Aerogel Ring-Imaging Cherenkov detector (ARICH) has been designed to provide PID in the forward end-cap region of the Belle II spectrometer. As a photon detector a Hybrid Avalanche Photo- Detector (HAPD), which was developed in collaboration with Hamamatsu Photonics, will be used. As the ARICH will be placed in 1.5T magnetic field, the HAPD must be immune to it.

A large area ring-imaging Cherenkov detector will be operated at the CLAS12 experiment at the upgraded continuous electron beam accelerator facility of Jefferson Lab for hadron identification.
With the new beam energy, the momentum range under study will range between 3 GeV/c and 8 GeV/c. The detector consist of areogel radiator, composite mirrors and photon detector and will be built with a...
Gamma ray induced air showers can be observed by particle detector arrays at high altitudes. The water-Cherekov detection technique has proven to result in robust observations of the gamma-ray sky around TeV energies and has been applied in observatories like Milagro and more recently in HAWC. The biggest challenge for these kind of observatories is to effectively reject background events from...
The Aerogel Ring Imaging Cherenkov (ARICH) counter is the particle identification device covering the endcap region in the Belle II detector. As a Cherenkov photon sensor a position-sensitive Hybrid Avalanche Photo-Detector (HAPD) will be used. In total 420 HAPDs will be arranged to cover the endocarp area. To operate HAPD six power lines with different voltages are needed. Negative voltage of...
In 2019 the LHCb RICH detector will be upgraded to increase the read out rate
from 1MHz to 40MHz. As a consequence, the current Hybrid Photon Detectors
(HPDs) will have to be replaced. Multianode Photomultiplier Tubes (MaPMT)
from Hamamatsu with 64-channels will be used: the 1-inch R13742 and the
2-inch R13743 MaPMTs (custom modifications of the MaPMTs R11625 and
H12699). Quality assurance...
The Latin American Giant Observatory (LAGO) is an extended cosmic ray observatory composed by a network of water-Cherenkov detectors (WCD) spanning over different sites located at significantly different altitudes (from sea level up to more than $5000$\,m a.s.l.) and latitudes across Latin America, covering a huge range of geomagnetic rigidity cut-offs and atmospheric absorption/reaction...
Micropattern Gaseous Detectors opened a novel way for
photon detection for RICH applications;
mostly using hole-type amplifiers like GEM and ThickGEM,
and hybrid structures based on the formers.
The main features are low ion backflow, high gain,
and possibility for suppressing the MIP signal.
Latter can enhance the dynamic range, and allow for high gain operation,
while using cost effective...
TORCH is a large-area precision time-of-flight detector based on the DIRC principle, proposed to provide positive particle identification of low momentum kaons for the LHCb experiment at CERN. The DIRC bar boxes of the BaBar experiment at SLAC could possibly be reused to form a part of the TORCH detector time-of-flight wall area.
For the implementation of the BaBar bars, new imaging and...
The increase in luminosity planned for the next LHC experiments upgrade is such that even detectors far from the interaction region will be exposed to considerable amount of radiation. The LHCb experiment at CERN is preparing for an important upgrade to be achieved in the years 2019-2020 in order to sustain higher instantaneous luminosities and read out the detectors at 40 MHz. The LHCb...
The CBM experiment at FAIR, Darmstadt, has recently bought 1100 HAMAMATSU H12700 photon sensors to equip the photon detection plane of the CBM RICH detector.
Delivery of these MAPMTs just started, and will continue until mid 2017.
This MAPMT features a clear single photon peak (PV $>1.5:1$) at high efficiency (peak quantum efficiency (QE) $\geq 30$\%) whilst having relatively low noise...
One of the biggest challenges for the upgrade of the LHCb RICH detectors from 2020 is to readout the photon detectors at the full 40 MHz rate of the LHC proton-proton collisions. A test facility has been setup at CERN with the purpose to investigate the behaviour of the Multi Anode PMTs, which have been proposed for the upgrade, and their readout electronics at high trigger rates.
The MaPMTs...
In the forward end-cap of the Belle II spectrometer, the proximity focusing RICH with aerogel radiator will be installed for charged particle identification. At the back side of the Hybrid Avalanche Photo Detector (HAPD), a low power front end electronics board will be mounted. The board consists of a 11 layer PCB with four custom ASICs on the HAPD side and a FPGA on the other side. The front...
The new aerogel radiator hybrid geometry CLAS12 RICH detector will be readout using $25000$ single photon sensitive pixels on a $1\ \rm m^{2}$ surface.
A modular on-detector electronics has been developed based on ASIC and FPGA.
It is capable of $100\ \rm\%$ detection efficiency at $50\ \rm fC$ and 3D-binary reconstruction (hit position and time) with $1 \ \rm ns$ resolution, $8 \ \rm \mu...
Very precise timing below the 100ps-mark is gaining importance in modern detector designs. Many technology demonstrators achieving this goal were based on the Cherenkov effect exploiting its prompt light emission. One common requirement is the necessity to compensate inherent walk effects to reach the sub-100ps timing precison.
In traditional approaches either the amplitude is measured in...
Silicon photomultiplier (SiPM) photodetectors perform well in many particle and medical physics applications, especially where good efficiency, insensitivity to magnetic field and precise timing are required. Recent developments in available devices and research which improved the understanding of SiPM response enable further improvement in the time resolution that can be achieved. We report...
