“…We demonstrated the feasibility of integrating AMCPs monolithically on readout electrodes, paving the road to a new variety of applications and broadening existing ones. Particle trackers and photon-counting imagers could feature a vertically integrated AMCP on readout electronics developed for nuclear physics, like Medipix2 26 27 25 and NINO 28 29 . Hybrid detectors 30 with AMCPs on solid-state detectors, like the Geiger-mode avalanche photodiode (G-APD) 31 32 30 , could take advantage of a double multiplication mechanism in a very compact and magnetic-insensitive design.…”

Microchannel plates are vacuum-based electron multipliers for particle—in particular, photon— detection, with applications ranging from image intensifiers to single-photon detectors. Their key strengths are large signal amplification, large active area, micrometric spatial resolution and picosecond temporal resolution. Here, we present the first microchannel plate made of hydrogenated amorphous silicon (a-Si:H) instead of lead glass. The breakthrough lies in the possibility of realizing amorphous silicon-based microchannel plates (AMCPs) on any kind of substrate. This achievement is based on mastering the deposition of an ultra-thick (80–120 μm) stress-controlled a-Si:H layer from the gas phase at temperatures of about 200°C and micromachining the channels by dry etching. We fabricated AMCPs that are vertically integrated on metallic anodes of test structures, proving the feasibility of monolithic integration of, for instance, AMCPs on application-specific integrated circuits for signal processing. We show an electron multiplication factor exceeding 30 for an aspect ratio, namely channel length over aperture, of 12.5:1. This result was achieved for input photoelectron currents up to 100 pA, in the continuous illumination regime, which provides a first evidence of the a-Si:H effectiveness in replenishing the electrons dispensed in the multiplication process.

“…Each FEE module features 24 differential input channels and outputs correspondent LVDS signal with the signal charge encoded in its width. The timing accuracy (RMS) can be better than 15 ps for each channel when the input charge is larger than 100 fC [19]. The FEE board is fixed on the surface of the aluminium gas box which contains the MRPC module in order to save space of connectors and cables.…”

The cosmic ray test of MRPCs for the BESIII ETOF upgrade

et al. 2016

In order to improve the particle identification capability of endcap time-of-flight (ETOF) at Beijing Spectrometer III, it is proposed to upgrade current ETOF detector with multi-gap resistive plate chamber (MRPC) technology aiming at extending ETOF overall time resolution to be 80-100 ps for π 's. The new ETOF system including MRPC detectors, front end electronics, CLOCK module, fast control boards and time-to-digital conversion modules, was built up and underwent 3-month cosmic ray test. The main purposes of the cosmic ray test are examining the construction quality of the system, testing the joint operation of all instruments and guaranteeing the system performance. The results show that MRPC time resolution is better than 80 ps, average efficiency is about 98.5 % and the noise rate of strip is 0.2 Hz/cm 2 at the threshold range for normal operation. These results indicate that the entire ETOF system would work well and satisfy the requirements of upgrade.

“…Each MRPC matches one FEE module with twenty four channels based on NINO [12], which features time-over-threshold (TOT) measurement. The timing accuracy is better than 15 ps RMS for each channel when the input charge is larger than 100 fC [13]. The FEE boards with connectors and cables are fixed on the surfaces of the aluminium boxes of the MRPC modules.…”
