High-temperature scintillation detectors are mainly used in the fields of petroleum logging and geological exploration field, which has special encapsulation requirement on the detectors and their components due to the harsh used environment, such as up to 175 degree C temperature, heavy shock(1000 g) and vibration(30g rms 50-1000 Hz). Epic crystal offer series of ruggedized scintillation detectors based on NaI(Tl), LaBr3(Ce) or Lithium6 glass with outstanding characters and relibility, approved by customers worldwide.
