These four pressure-tested this vessel to check for leaks and certify it for use. This is the pressure-containing vessel for a new liquid-argon bubble chamber being constructed by the SBC collaboration. The vessel will be used for coherent elastic neutrino-nucleus scattering detection at a reactor after taking calibration data underground at NuMI. An identical chamber will be built at SNOLAB to search for WIMPs as well. From left: TJ Whitis, Matt Bressler, Rocco Coppejans, Eric Dahl.
Humberto Gonzalez (on right) of the PPD Detector Development and Operations Departments at SiDet helps visitor Caleb Fangmeier, a graduate research assistant from the University of Nebraska-Lincoln, hook up the vacuum that will be used for the pick-n-place step in the assembly of this gantry. The gantry will be used for assembling CMS timing layer modules.
Aloke Das is a Ph.D. student at the National Institute of Science Education and Research in India, currently visiting Fermilab and working under Leonard Spiegel with the outer tracker module system test in the detector test area at SiDet. Aloke will be leaving Fermilab at the end of November, and this morning he woke up to a nice surprise: snow!! He said that this was the first time ever in his life to witness snow fall. He was happy to be able to see it and touch it. I figured he needs the winter experience, so the photographer threw a snowball at him!
