Dr. David Woodward and Corey Herr are at SLAC, getting the LZ dark matter experiment ready to go!  They were working on a test of the thermosyphon system that will be used to cool down the detector and liquify the xenon inside it.

(SLAC is the former “Stanford Linear Accelerator Center”, a national lab located in the bay area in California. It’s part of the LZ Collaboration, and it’s where a lot of the commissioning of the LZ detector is taking place prior to assembly underground in South Dakota!)
