Helium Liquefier

Our University has sacrificed a parking lot to realize this project:


It is an expansion to the machine shop which among other things now hosts this helium liquefier:


Our lab is now connected to the helium recovery system, and we are building our first “wet” cryostat in which liquefied helium is used to cool a sample to 4.2 degrees Kelvin (-269 degrees centigrade). We are also now officially shopping for a used wet dilution refrigerator.
