David at SURF (1)

Dr. David Woodward of Penn State went to the Sanford Underground Research Facility (SURF)in South Dakota since November, to receive and start the assembly of the LZ Test Cryostat, created by the Penn State group to test the cryogenic and liquid xenon systems of the LZ experiment before the actual detector is in place. He has also been working on the assembly of the detector itself, and the photo below shows him placing Teflon panels in the surface of the inner cryostat, used to enhance our light collection!
