LaBr3:Ce Scintillation Probe > LaBr3Ce Scintillation Probe

Introduction

The scintillation probe of LaBR series are made up of LaBr3:Ce fast-response photomultiplier voltage division circuit fast-response charge sensitive preamplifier and the metal case. Because the optimal design of direct coupling the probe has many advantages like the high energy resolution good energy linear and the fast response. It widely used in nuclear detection technology.
