In this paper, the simulation model of the range extender system is established to calculate the torsional vibration performance of the shafting system, and the calculation results of the speed nonuniformity and torsional vibration ampli... YF Chen,HH Feng - 《Journal of Physics Conference》 被引...
The Large PMT Quantum Efficiency Test Platform: Volume 2 Photomultiplier tubes are widely used in physics experiment, industrial production, medical equipment and other fields. The performance of the photocathode is very important for the large area PMT. A platform for the photocathode studyin... F...
In this paper, we present the design concept, calibration and performance of the PMT system in the pathfinder experiment. 展开 关键词: Cherenkov detectors Large detector systems for particle and astroparticle physics Neutrino detectors Photon detectors for UV, visible and IR photons (vacuum) (...
With commercially-available multi-anode microchannel plate photomultiplier tubes (MCP-PMT) and electronics, resolutions significantly better than 10 psec have been achieved in small systems with a few readout channels[1,2]. For large-scale time-of-flight systems used in particle physics, which may...
The optimization work of a newly proposed 20-in. photomultiplier tube based on dynode and microchannel plates (Dynode-MCP-PMT) are conducted in this paper. Three-dimensional models are developed in CST STUDIO SUITE to systematically investigate the effec
An unexpected intra-anode gain variation is carried out. In this paper we present the results obtained with this PSPMT regarding imaging performances principally addressed to nuclear medicine application.[Copyright &y& Elsevier]Nuclear Physics B Proceedings Supplement...
