摘要:

本文是JINST上发表的发射前状态LFI论文的一部分:http://www.iop.org/EJ/journal/-page=extra.proc5/jinst普朗克LFI辐射计链组件(RCA)已在两个专用的低温设施中进行了校准。本文介绍了实验设备和相关仪器。单链的主要卫星热界面必须复制,稳定性要求必须得到满足。讨论了系统设计、出现的问题和改进方案。低温设置的性能报告。

英文摘要:

This paper is part of the Prelaunch status LFI papers published on JINST: http://www.iop.org/EJ/journal/-page=extra.proc5/jinst The Planck LFI Radiometer Chain Assemblies (RCAs) have been calibrated in two dedicated cryogenic facilities. In this paper the facilities and the related instrumentation are described. The main satellite thermal interfaces for the single chains have to be reproduced and stability requirements have to be satisfied. Setup design, problems occurred and improving solutions implemented are discussed. Performance of the cryogenic setup are reported.
