GSI未来的超重元素合成实验计划需要库仑势垒或以上的高强度重离子束，超出了GSI-UNILAC（通用线性加速器）的能力。此外，现有的GSI加速器链将用作FAIR（反质子和离子研究设施）的注入器，主要以低重复率提供高功率重离子束。由于这一限制，我们提出了一种新的专用超导 (sc) 连续波 (cw) 直线加速器，以保持 GSI 超重元素 (SHE) 研究项目的竞争力。第一个直线加速器部分的建设已于2016年第三季度完成。它作为原型展示了其在现实加速器环境中的可靠可操作性。该演示低温模块包括作为整个项目关键组件的 sc 217 MHz 横杆 H 模式 (CH) 多间隙腔和两个 sc 9.3 T 螺线管。腔体的性能已在低温下进行了广泛的测试。在本文中，将介绍初始冷测试的测量结果。
The future experimental program of super heavy element synthesis at GSI desires high intense heavy ion beams at or above the coulomb barrier, exceeding the capabilities of the GSI-UNILAC (Universal Linear Accelerator). Additionally, the existing GSI accelerator chain will be used as an injector for FAIR (Facility for Antiproton and Ion Research) primarily providing high power heavy ion beams at a low repetition rate. Due to this limitations a new dedicated superconducting (sc) continuous wave (cw) linac is proposed to keep the Super Heavy Element (SHE) research program at GSI competitive. The construction of the first linac section has been finished in the 3 quarter of 2016. It serves as a prototype to demonstrate its reliable operability in a realistic accelerator environment. This demonstrator cryomodule comprises the sc 217 MHz crossbar-H-mode (CH) multigap cavity as the key component of the whole project and two sc 9.3 T solenoids. The performance of the cavity has been extensively tested at cryogenic temperatures. In this contribution the measurement results of initial cold tests will be presented.
