Abstract
The resistance R of a "low-resistance" microchannel plate (MCP) electron mu
ltiplier was measured over the extended temperature range 4-293 K. The rati
o R(T)/R(293 K) reached values of 10(2), 10(3) and 10(6) at temperatures T
= 59, 40 and 19 K, respectively. These results are interpreted in terms of
variable range hopping conduction mechanisms in the reduced lead silicate M
CP glass. The results may be important for cryogenic charged particle detec
tion using MCPs, as, for example, in a recent proposal for a quantum comput
