2014年串列加速器升级工程100 MeV回旋加速器安装调试取得了较大的进展。本文简要介绍了其中低温传输管线的改进工作。1简介100 MeV强流回旋加速器低温传输管线的功用为连接低温冷板及低温气氦制冷机,将气氦制冷机产生的冷量在损失尽量少的情况下传递给低温冷板,使冷板降温,从而实现低温排气的功能。其主要性能参数:传输冷量功率为200 w@20 K、1 600 W@80 K;工作温度为20 K;低温传输
Great progress has been made in the installation and commissioning of the 100 MeV cyclotron in the 2014 Tandem Accelerator Upgrade Project. This article briefly introduces the improvement of low temperature transmission lines. 1 Brief Introduction The function of the 100 MeV high-pressure cyclotron cryogenic transfer line is to connect the low-temperature cold plate and the low-temperature helium heat exchanger, and transfer the cold capacity generated by the gas helium refrigerator to the low temperature cold plate with the loss as little as possible so that the cold plate Cooling, in order to achieve the function of low temperature exhaust. The main performance parameters: transmission cooling capacity of 200 w @ 20 K, 1 600 W @ 80 K; working temperature is 20 K; low temperature transmission
