Triggered by the need of a detection system to be used in experiments of nuclear fusion in laser-generated plasmas, we developed an imaging technique for the measurement and calibration of the scintillation light yield of scintillating materials. As in such experiments, all the reaction products are generated in an ultrashort time frame, the event-by-event data acquisition scheme is not feasible. As an alternative to the emulsion technique (or the equivalent CR39 sheets) we propose a scintillating screen readout by means of a high performance charge coupled device camera. Even though it is not strictly required in the particular application, this technique allows the absolute calibration of the scintillation light yield.
受用于激光产生等离子体核聚变实验的检测系统需求的推动,我们开发了一种用于测量和校准闪烁材料闪烁光产额的成像技术。在这类实验中,所有反应产物都是在超短时间内产生的,逐事件数据采集方案不可行。作为乳剂技术(或等效的CR39薄片)的替代方案,我们提出使用高性能电荷耦合器件相机读取闪烁屏。即使在特定应用中并非严格必需,但该技术允许对闪烁光产额进行绝对校准。
