The PMT arrays for the LUX-ZEPLIN (LZ) dark matter experiment have been successfully assembled – now LZ has its eyes! LZ will have a total of 494 of these extremely sensitive light sensors in the main detector… not to mention 131 more in the xenon skin and 120 in the water tank! LZ is well on its way for starting in 2020!
In preparation to test the xenon circulation system for the LUX-ZEPLIN (LZ) dark matter experiment, Dr. David Woodward of Penn State carefully positioned a tower holding a stainless-steel test cryostat. The LZ collaboration will circulate liquid xenon through the test cryostat to ensure the system will work properly when the experiment begins operations in 2020.
