Photomultiplier tube (FR)produces photoelectron through photon's incidence to photocathode, then the photoelectron enters multiplication system through ting electron optical system, and finally forms output current or voltage after twice emission, many times multiplying and collecting by anode, which is widely applied to the fields of photon counting, scinticounting and oil exploration. The photomultiplier tubes applied to oil exploration include FR***5, FR***0, FR***5, FR***9, FR***9, etc with the temperatures of **5. C and **0. C. The cathode sensitivity(normal temperature)of FR***0, FR***3 pipe is 9μ A/1m, and that of FR***6FR***0 pipe is *0μ A/1m; The anode sensitivity(normal temperature) of FR***0, FR***3 pipe is *0μ A/1m when the Max. Voltage is ***0V, and that of FR***6pipe is **0A/1m when the Max. Voltage is ***0V and that of FR***0 pipe is **0A/1m when the Max. Voltage is ***0V. At the temperature of **0. C, when the plateau length of output voltage is larger than **0V, the pulse amplitude reduces *0% under the high temperature conditions.

At the temperature of **0. C, when the plateau length of output voltage is larger than **0V, the pulse amplitude reduces *0% under the high temperature conditions.

The photomultiplier provides extremely high sensitivity and ultra-fast response. Photomultiplier tubes (PMT) have high bandwidth and noise-free gain on the order of a million. This makes them ideal for the detection of extremely low light or short pulses of light. Photomultipliers can be used to detect photons from **5nm to ***0nm. A typical Photomultiplier consists of a photoemissive cathode (photocathode) followed by an electron multiplier and an electron collector (anode).
