Caltech Electron Paramagnetic Resonance (EPR) Facility
The Caltech EPR facility is equipped with two Bruker EPR spectrometers, an EMX X-band continuous-wave (CW) EPR spectrometer, and a newly acquired Bruker ELEXSYS E580 pulse EPR spectrometer capable of pulse and CW EPR spectroscopy at both X and Q-bands, as well as a variety of electron-electron double resonance (ELDOR) and electron-nuclear double resonance (ENDOR) spectroscopies. Groups or research laboratories interested in using instrumentation in the facility are welcome to visit the laboratory in the sub-basement of Crellin Hall (B264) or email Paul Oyala at email@example.com.
Bruker ELEXSYS - E580 X,Q-band pulse EPR spectrometer
Bruker EMX X-band CW-EPR Spectrometer
Located in a renovated lab in the sub-basement of Crellin (B264), this instrument is a state-of-the-art Pulse and CW EPR spectrometer from Bruker capable of CW EPR, Pulse EPR, and ELDOR and ENDOR experiments at both X- and Q-Bands (9 GHz and 34 GHz, respectively). Additionally, it is equipped with an Arbitrary Waveform Generator (AWG) integrated into the pulse-forming unit which is capable of generating shaped pulses for advanced pulse EPR applications at either operating frequency.
Located in the basement of Crellin in B160, this instrument is an X-band CW EPR spectrometer capable of CW experiments from cryogenic temperatures to room temperature.
