麝香是一种新的1.1毫米波段接收器,于2021年最后一个季度安装在墨西哥普埃布拉Volc 'an Sierra Negra顶部的50米大型毫米望远镜上,并于2022年全年投入使用。麝香采用了一种新型的冷却链,包括一个商业脉冲管冷却器,两个热级的被动切换连续吸附冷却器,和一个最终的微型稀释制冷机。通过该系统麝香在焦平面上实现了120 mK的连续温度,并在准备测试期间在此温度下连续运行超过100天。通过最大限度地减少所需的氦-3量,麝香低温系统的设计产生了一个可靠的,具有成本效益的冷却平台。在这里,我们提出了低温设计和性能的麝香的天空,并比较这期间实现的部署准备测试在卡迪夫(英国)。我们考虑冷却时间和达到的基本温度。我们看看搬迁的脉冲管冷却仪器从一个50 Hz的电源供电的开发实验室运行到一个网站运行在60 Hz的操作的影响。最后,我们描述的过程中准备的麝香工具的航运和评估的成功,这一过程中所需的补救工作抵达。
MUSCAT is a new 1.1 mm band receiver which was installed on the 50 m Large Millimeter Telescope atop Volc´an Sierra Negra in Puebla, Mexico during the final quarter of 2021 and commissioned on sky throughout 2022. MUSCAT uses a novel cooling chain consisting of a commercial pulse tube cooler, two thermal stages of passively-switched continuous sorption coolers, and a final miniature dilution refrigerator. Through this system MUSCAT achieves a continuous temperature of 120 mK at the focal plane and has shown continuous operation at this temperature for greater than 100 days during readiness testing. Through minimising the amount of helium-3 required, the design on MUSCAT’s cryogenic systems produced a reliable, cost-effective cooling platform. Here we present the cryogenic design and performance of MUSCAT on-sky and compare this to that achieved during deployment-readiness testing at Cardiff (UK). We consider both cooldown time and achieved base temperature. We look at the impact on operation of relocating a pulse-tube cooled instrument from a development lab running on a 50 Hz mains electricity supply to a site running at 60 Hz. Finally, we describe the process of preparing the MUSCAT instrument for shipping and assess the success of this process in terms of remedial work required upon arrival.
