The FASER detector

open access: yesJournal of Instrumentation
Abstract FASER, the ForwArd Search ExpeRiment, is an experiment dedicated to searching for light, extremely weakly-interacting particles at CERN's Large Hadron Collider (LHC). Such particles may be produced in the very forward direction of the LHC's high-energy collisions and then decay to visible particles inside the FASER ...

Imaging the coupling of terahertz radiation to a high electron mobility transistor in the near-field [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2009
We used AlGaN/GaN high electron mobility transistors as room-temperature direct detectors of radiation at 0.15 THz from a free electron laser, hence 5 times higher than their cutoff frequency of 30 GHz.
