CH423-02 High Temperature LaBr3(Ce) Scintillation Detector (Energy spectrum measurement while drilling)

CH423-02 detector is a scintillation detector while drilling. It integrates LaBr₃(Ce) scintillator, high temperature PMT and high linear voltage divider circuit. The unique design ensures the stable performance of the detector in high temperature vibration environment.

LaBr₃(Ce) is a new type of scintillator. Compared with the traditional NaI(Tl) scintillator, LaBr₃(Ce) has the advantages of better pulse amplitude resolution, higher detection efficiency for high energy ray, fast decay time and better temperature characteristic.

It is mainly used to measure formation elements in oil logging.

Specifications

Model

CH423-02 High Temperature LaBr3(Ce) Scintillation Detector (Energy spectrum measurement while drilling)

1) Test with¹³⁷Cs;

2) Tested in natural gamma environment;

3) The detector is respectively placed in 6 directions of X+, X-, Y+, Y-, Z+ and Z-, and the output pulse amplitudes of the 6 directions are obtained through test in sequence，taking X+ as the reference, the other 5 directions is compared with the reference amplitude, and the maximum value of the change of the 5 directions relative to the reference amplitude is calculated;

4) Change in vibration state relative to non-vibration state.;

5) Resonance frequency ≥ 1000Hz;

6) Tempreature change rate during detector operation and storage≤3℃/min;

7) The detector can only be operated under negative high voltage conditions, the maximum high voltage is 1800V.
