The magnetic field is supplied by a 12 T cryogen-free sweepable superconducting magnet system. Soon to be upgraded to a high-power (100 W) traveling wave tube amplifier built by the Luhmann group at the UC Davis Millimeter-Wave Technology Center. Currently equipped with a ~ 200 mW microwave amplification system similar to our D-band instrument. Capable of ESEEM, HYSCORE, ENDOR, and EDNMR techniques.Ĭapable of performing CW and pulse EPR techniques 263 GHz. The Oxford-CF935 liquid helium cryostat allows for EPR at pumped helium temperatures (down to ~1.4 K). Equipped with a Janis liquid He immersion cryostat for EPR at pumped helium temperatures (down to ~1.2 K).Įquipped with a ~ 200 mW microwave bridge at 130 GHz and an 8 T cryogen-free sweepable superconducting magnet system. Capable of performing pulse EPR techniques in the 8-18 GHz range. The first pulse spectrometer built by Dave at UC Davis. Capable of variable temperature EPR down to 77 K.Ī home-built 100 W pulse EPR spectrometer capable of ESEEM, HYSCORE, and DEER at liquid helium temperatures. Equipped with a 10W microwave bridge.Įquipped with a high-sensitivity resonator (ER4122SHQE). Supports a number of different resonators: a high-sensitivity resonator (ER4122SHQE) and a dual-mode resonator (ER4116DM) primarily for parallel mode EPR.īruker ELEXSYS E580 X and Q-band Pulse SpectrometerĬapable of performing pulse techniques including ENDOR, ESEEM, HYSCORE, and DEER at liquid helium temperatures. The three other spectrometers are Bruker instruments: a Bruker ECS X-band (9 GHz) continuous-wave (CW) spectrometer, a Bruker E500 X-band CW spectrometer, and a Bruker E580 X and Q (34 GHz) band pulse spectrometer.īruker ELEXSYS E500 X-Band CW SpectrometerĮquipped with an Oxford Instruments ESR900 cryostat capable of low temperature EPR (4.5 K). Four of our EPR spectrometers are home-built pulse EPR spectrometers that operate at 8-18 GHz, 31 GHz, 130 GHz, and 263 GHz. The CalEPR facility at UC Davis is home to seven EPR spectrometers at frequencies ranging from 8 - 263 GHz.
