Design of Optical System for Scintillator Beam Collimation
摘要
Abstract
To achieve more efficient collection and high quality collimation of scintillation light,enhance the detection efficiency of particle beams,and facilitate subsequent experiments such as light beam control and deflection of scintillator,a coaxial beam collimation system and an off-axis beam collimation system are proposed,respectively.The parameters of devices in the systems,such as freeform lenses and conic surface reflector are optimized.And optical software LightTools is used to simulate the beam collimation systems of scintillator.The simulation results show that the designed systems effectively achieve the collimation of scintillation light.The off-axis beam collimation system with freeform surface lens and off-axis reflector significantly reduces the beam divergence angle from+40° to+5°.The light energy utilization rate can reach over 96％,with the in-beam angle light energy utilization rate exceeding 83％.The control of beam propagation direction is achieved and collection efficiency of scintillation light is improved.关键词
