Assembly of the “heart” of LZ completed!

Th LUX-ZEPLIN (LZ) Collaboration has finished putting together the Time-Projection Chamber, the ‘heart’ of the LZ dark matter detector.  The TPC is very complex system, and it’s a major achievement to have it fully assembled:

LZ TPC Completed

Neutrino Day 2019

The Penn State group participates in the Neutrino Day 2019!

Neutrino Day is the science festival organized by the Sanford Laboratory in Lead, SD, where the LZ dark matter detector is located.  Penn State graduate students Dan Kodroff and Gavin Cox volunteered to help with the festival, hosting a booth to explain the some cosmology and dark matter to visitors!

Penn State’s LZ test cryostat on site!

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.

David at SURF (2)

Dr. David Woodward of Penn State has been at the Sanford Underground Research Facility (SURF) in South Dakota since November, working on 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. Some more details can be found here at the SURF newsletter:

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!

LUX Analysis Workshop at Penn State 2018

We have just hosted the LUX Analysis Workshop here at Penn State University! The workshop was chaired by Dr. David Woodward, the LUX Analysis Coordinator and postdoc at Penn State, with help from Profs. Carmen Carmona and Luiz de Viveiros.

The LUX Dark Matter experiment has completed its science run and was disassembled in 2017, to make room for the next generation LUX-ZEPLIN (LZ) Dark Matter detector. Although its primary mission has been completed by setting world-leading constraints on Dark Matter cross-sections at the time, it has left a rich dataset that is still being actively mined for new physics, with Penn State leading the charge!

Carmen Carmona elected to LZ Executive Board

Prof. Carmona was elected as one of the four voting members of the LZ Executive Board, a small committee charged with providing leadership and guidance for the LZ experiment (which has more than 250 members!). The responsibilities of the Executive Board include guiding the technical strategy of the collaboration and the experiment, and advising the spokespersons on scientific and financial matters.

Congratulations!
