Silicon photomultipliers (SiPM) are candidates selected as the potential photodetector technology for the dual-radiator Ring-Imaging Cherenkov (dRICH) detector at the future Electron-Ion Collider (EIC). SiPM optical readout offers a large set of advantages being cheap devices, highly efficient and insensitive to the high magnetic field (~ 1.5 T) at the expected location of the sensors in the...
An optimized design and process flow in a specialized 350 nm CMOS technology yields Single-Photon Ava-lanche Diodes (SPADs) with extremely low Dark Count Rates (DCR). They show optimal properties for de-tecting visible and near infrared photons in low quantity with high timing resolution. These characteristics are crucial for building up Silicon Photomultipliers (SiPM) to detect Cherenkov...
PANDA is one of the main experiments at the FAIR facility at GSI which will study different aspects in QCD by, e.g., performing hadron spectroscopy, among others in searching for glueballs and exotic states, and by investigating hyperons. The PANDA experiment will use an antiproton beam in the momentum range of 1.5 to 15 $\mathrm{GeV/c}$ colliding with a stationary target. Due to...
Researchers at IHEP have conceived two types of MCP-PMTs for the photon detection in particle physics. One is the 20 inch Large MCP-PMT (LPMT) with small MCP units in the large area PMTs for the neutrino detection. This LPMT has already been mass produced more 15K pieces in the JUNO experiment, and has also been evaluated by the PMT group in LHAASO and HyperK. The other is the 2 inch Fast...
Photek have developed a square microchannel plate (MCP) PMT using 6 µm pore MCPs to achieve superior timing, compared to the previous generation which used 15 µm pores. The native anode pattern is 64x64, but for this module the pattern is ganged to a 16x16 design using an epoxy bonded PCB giving an anode size of 3.3×3.3 mm2 in a 53×53 mm2 active area. The electronic front-end is the TOFPET2d...
The BelleⅡ experiment is a high luminosity electron and positron collider experiment at SuperKEKB in Japan. In this experiment, we aim to measure B-decay precisely and search for effects from New Physics. We started physics data taking with the whole detector system in March 2019. The Time-of-propagation (TOP) counter is a detector for particle identification in the barrel region of the BelleⅡ...
The development of a single-photon detector based on a vacuum tube, transmission photocathode, microchannel plate and CMOS pixelated read-out anode is presented. This imager will be capable of detecting up to 1 billion photons per second over an area of 7 cm$^2$, with simultaneous measurement of position and time with resolutions of about 5 microns and few tens of picosecond, respectively. The...
The upgraded LHCb RICH detectors are equipped with Multianode Photomultiplier Tubes, covering a total area of approximately 4 square metres. In order to achieve the same excellent hadron identification performance as during LHC Run 1 and 2 at five times the instantaneous luminosity, the photon detectors have to be sensitive to single photons with repetition rates of up to $100~\text{MHz/cm}^2$...
Progress on coupling MPGD-based photon detectors with nanodiamond photocathodes
A Bari-Trieste Collaboration
Abstract:
Hydrogenated nonodiamond grains represent an alternative to CsI for detection of single VUV photons in gaseous detectors. A dedicated R&D study on the performance of nanodiamond photocathodes coupled to THGEM-based photon detectors is ongoing.
The first phase of these...
Large Area Picosecond Photon Detectors (LAPPDs) are micro-channel plate (MCP) based photosensors featuring hundreds of square centimeters of sensitive area in a single package and capable of providing timing resolution on the order of 30-50 ps for single photon detection. One of the recent LAPPD models (Gen II) gives the opportunity of building finely pixelated 2D readout configurations which,...
