A close look at the bubble chamber.

A physicist making great advances in particle detector technology, Estrada is recognized by the American Physical Society Division of Particles and Fields for his creation and development of novel applications for CCD technology that probe wide-ranging areas of particle physics, including cosmology, dark matter searches, neutrino detection and quantum imaging.
Throwback Thursday to some frosty days at Fermilab.
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.
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!
Some interns have already finished their work at the lab, and others are here for a bit longer. It would be very nice to see them again next year.
From Science News, Aug. 8, 2019: It’s a news flashback. Science News excerpts a bit on the Fermilab Bubble Chamber from their August 16, 1969, issue. “Use by visitors is expected to be especially large at the National Accelerator Laboratory now under construction at Batavia, Ill…. NAL staff and consultants agree that the laboratory will need a large bubble chamber, and it now plans to build one in collaboration with Brookhaven National Laboratory.”
The birch tree in the SiDet courtyard is covered with ice. Such beauty!
January snow brings a wintry dusting in the SiDet courtyard.
