Cold Electronics Help Scientists Spot Elusive 'Ghost' Particles
Brookhaven National LaboratoryNestled inside the massive MicroBooNE detector, part of a new neutrino experiment just getting underway at the U.S. Department of Energy's (DOE) Fermi National Accelerator Laboratory, lie 50 circuit boards packed with custom-built microelectronics. These circuits were designed by engineers at DOE's Brookhaven National Laboratory to operate while immersed in liquid argon, a cryogenic liquid that boils at a biting -186 degrees Celsius or -303 degrees Fahrenheit.
