His first eight years were spent as a technician in the Hydrogen Target/Cryogenic Device Group. Around 1989, he moved into new territory. For the next 22 years, he would move between beamline operations, collider cryogenic operations — including the commissioning of the CDF cryo system and detector — and the CDMS experiment in Soudan, Minnesota, where he helped install the dark matter experiment’s dilution refrigerator. At the new liquid-argon test facility, he worked with the installation and commissioning of MicroBooNE, including the high-voltage power lead testing.
In 2015, he joined the Neutrino Division, working on the installation of the Short-Baseline Neutrino Program’s near- and far-detector systems.
“I have many great memories, have enjoyed good times and am grateful for the wonderful people that I’ve had the opportunity to work with,” Johnson said. “There are too many to list!”
During retirement, he will continue to travel with his wife Mary, visiting many new and far-off places. He looks forward to spending more time with his family and friends, chipping away at his list of home projects and getting more sleep.
“Bryan worked on hydrogen targets in the early years. He was rightly proud of that work. He was also an integral member of the DZero operations group, working many long shifts and helping DZero reach its goals. His knowledge of cryo systems will be missed,” said Pete Simon, Fermilab operations specialist. “He organized great lunchtime cookouts, too, and we never ate so well as when Bryan was at the grill.”
Wish Johnson well over refreshments in the MINOS service building on Tuesday, Oct. 15, between 1 and 3 p.m.
