我们提出了最近的长期稳定性测试结果的低温环境控制系统（ECS）的可居住区行星地球（HPF），一个近红外超稳定光谱仪在180开尔文运行。高精度径向速度（<1 m =s）仪器要求有极好的温度和压力稳定性，因为温度和压力的变化很容易引起仪器每秒几十到几百米的漂移。本文介绍了HPF在180 K工作温度下的长期稳定性试验结果，表明HPF ECS在0：6 mK水平下稳定15天，在<10-7 Torr水平下稳定数月。
We present recent long-term stability test results of the cryogenic Environmental Control System (ECS) for the Habitable zone Planet Finder (HPF), a near infrared ultra-stable spectrograph operating at 180 Kelvin. Exquisite temperature and pressure stability is required for high precision radial velocity (< 1m=s) instruments, as temperature and pressure variations can easily induce instrumental drifts of several tens-to-hundreds of meters per second. Here we present the results from long-term stability tests performed at the 180K operating temperature of HPF, demonstrating that the HPF ECS is stable at the 0:6mK level over 15-days, and <10-7 Torr over months.
