CCD Cooling Build

Jason finished assembling our new CCD (and shutter) cooling system in the mirror lab yesterday. After several tries, and finally replacing the threaded cap that wouldn’t hold pressure, the system passed a pressure and operational test. It’s on its way to Pasadena, and from there to Chile.

Here Jason is installing the drain valve on the tank outlet.
These are our CCD cold plates, and the famous shutter, with coolant flowing through them.
Just after pressurizing the system.
And after about 10 minutes, with the pump running.
