Detailed introduction

Lanthanum Bromide LaBr3(Ce) Scintillation Radiation Detector
  • High light output and fast decay time output pulses.
  • Better energy resolution and stability than NaI(Tl).
  • Higher throughput at high input count rates.
Lanthanum bromide or LaBr3(Ce) is a new generation of inorganic scintillation gamma ray detectors. LaBr detectors have higher resolution and faster light decay times.

When used with ORTEC's digital electronics, these detectors offer higher resolution, better pulse shape and temperature stability compared to NaI(Tl).

    Lanthanum Bromide Scintillation Radiation Detector ComparisonHigher resolution and efficiency
    As shown in the picture1As shown,LaBrThe resolution performance ratio ofNaI(Tl) system is higher than approx.2times. Note thatNaI(Tl) detectors and lanthanum bromide detectors cannot reachHPGeDetector resolution. For the same volume,LaBrThe efficiency isNaI(Tl) about1.3times, and the decay time constant is slightly larger thanNaIdetector decay time10% (see table1). On the basis of optoelectronics output,LaBrThanNaI(Tl) has higher efficiency and temperature stability

    High count rate compatibility
    Lanthanum bromide detectors can operate over a wide dynamic range of count rates with little change in energy resolution.
