摘　　要：目的:设计一种新型热释光自动快速退火冷却装置,以提高热释光探测元件的剂量学性能。方法:装置设计由金属框架、冷却底板、风机及小型玻璃门电冰箱等组成。金属框架包括顶框及具有高低调节功能的支撑柱,顶框上固定一风机,风机设有串联的手动及与电冰箱门连锁的开关,冷却底板中心为探测器退火盘的位置标志,其旁有安放水银温度计的凹槽。结果:该装置散热效率高,在满足不同热释光探测器退火冷却要求的同时,保证了探测器的灵敏度和重复性,减少了热释光辐射剂量测量中的误差。结论:新型热释光自动快速退火冷却装置结构简单,成本较低,冷却效率及自动化程度高,适用于不同热释光探测器的不同退火冷却条件,对加强热释光测量系统的质量控制起着重要作用。Objective: To design a new kind of automatic rapid anneal-cooling device with thermoluminescence so as to enhance the dosimetry performance of thermoluminescent detector. Methods: The device was composed of a metallic frame, a bottom board for cooling, an air blower, a small refrigerator with the glass door. The metallic frame included the upper frame and support columns with high and low adjustment functions. And the air blower was fixed on the upper frame, and it was equipped with two switches which included a series-wound manual switch and a switch that was connected with the door of refrigerator. The center of the cooling baseboard was the position sign of the annealing plate of detector, and there was a groove of mercurial thermometer aside the center. Results: The heat dissipation efficiency of device was high, and it met the requirements of anneal-cooling of different thermoluminescence detectors, in the meanwhile, it guaranteed the sensitivity and reproducibility. Besides, it also reduced the error of thermoluminescence dosage in measurement. Conclusion: The new type of device has series of advantages include simple structure, low cost, high cooling efficiency and high level automation, which is suitable for different annealcooling conditions of different thermoluminescence detectors. It plays a vital role in strengthening quality control of thermoluminescence measurement system.
