Cooling Experiment of Camera Modules is Going on

The cooling experiment of camera modules for spectrograph is going on at Johns Hopkins University, the US. In order to observe faint stars and galaxies, astronomical detectors in visible and near infrared are used under very low temperature (-100 degree Celsius / -148 degree Fahrenheit or less than it) and high vacuum (less than one billion of atmospheric pressure). By this experiment… Read more »
