Microchannel plates phototubes in high magnetic field


  • Mr. Alexandr KATCIN

Primary authors


Microchannel plate photomultiplier tubes (MCP PMT) have good immunity to magnetic field and excellent time resolution. The influence of magnetic fields up to 4.5 T on the parameters of several MCP PMT designs was studied. PMTs with two, three and four MCPs were tested in magnetic fields. The tested samples have different diameters of MCP pores: 3.5, 6, 8 and 10 microns. Dependencies of the time resolution, the gain and the photoelectron collection efficiency on magnetic field are presented.
