Photomultiplier tube (FCR)
Detail

Photomultiplier tube(FCR) produces photoelectron through photon's incidence to photocathode, thenthe photoelectron enters multiplication system through inputting electronoptical system, and finally forms output current or voltage after twiceemission, many times multiplying and collecting by anode, which is widelyapplied to the fields of photon counting, scinticounting and oil exploration.

Thephotomultiplier tubes applied to oil exploration include FCR-1185, FCR-1110, FCR-1125,FCR-1159, FCR-1119 etc, with the temperatures of 125 and 150 . The cathode sensitivity-normal temperature of FCR-1110, FCR-1163 pipe is9μA/1m, and that of FCR-1160, FCR-1170pipe is 10μA/1m; The anode sensitivity of FCR-1110, FCR-1163pipe is 30μA/1m when the Max. voltage is 1800V, and that of FCR-166 pipe is 100A/1m when the Max. voltage is 1250V and that of FCR-170pipe is 200A/1m when the Max. voltage is 1250V. At thetemperature of 150C, when the plateaulength of output voltage is larger than 150V, the pulse amplitude reduces 50%under the high temperature conditions.
