伯明翰辐射装置是2013年在伯明翰大学使用医学物理MC40回旋加速器研制的。它可以在80 S上获得1015(1 MeV中子当量)cm−2的高亮度大型强子对撞机的注量,质子束流为1μA,因此可以有效地评估用于大型强子对撞机的探测器技术和新器件的性能和耐用性。硅传感器和无源材料的辐照可以在一个温度控制的冷箱中进行,该冷箱在均匀的光斑中连续移动。这种移动由预配置的XY轴笛卡尔机器人扫描系统提供。2014年,冷却系统和冷藏箱从循环乙二醇式冷冻机系统升级为液氮蒸发系统。新的冷却系统在30分钟内实现了−50°C的稳定温度,目标是在辐照期间将传感器上的温度保持在0°C以下。本文回顾了新冷却系统的设计、开发、调试和性能。
Abstract The Birmingham Irradiation Facility was developed in 2013 at the University of Birmingham using the Medical Physics MC40 cyclotron. It can achieve High Luminosity LHC (HL-LHC) fluences of 10 15 (1 MeV neutron equivalent (n eq)) cm− 2 in 80 s with proton beam currents of 1 μA and so can evaluate effectively the performance and durability of detector technologies and new components to be used for the HL-LHC. Irradiations of silicon sensors and passive materials can be carried out in a temperature controlled cold box which moves continuously through the homogenous beamspot. This movement is provided by a pre-configured XY-axis Cartesian robot scanning system. In 2014 the cooling system and cold box were upgraded from a recirculating glycol chiller system to a liquid nitrogen evaporative system. The new cooling system achieves a stable temperature of− 50° C in 30 min and aims to maintain sub-0° C temperatures on the sensors during irradiations. This paper reviews the design, development, commissioning and performance of the new cooling system.
