Bruker X/Q

The St Andrews EPR facility is equipped with a BRUKER ELEXSYS E580 spectrometer running at X and Q-bands and having, in addition to SPFU and MPFU channels, an integrated AWG for generating shaped pulses. The spectrometer offers the ability to perform pulse and CW EPR experiments at both frequencies and it is equipped with a Cryogen-Free Variable Temperature Cryostat (CF-VTC from CRYOGENIC) permitting measurements between 1.8K and 300K.

At X-band (~10 GHz, 1 kW TWT Amplifier), four resonators are available with optical access:

  • ER 4118X-MS3 Split Ring Resonator,
  • ER 4118X-MS5 Split Ring Resonator,
  • ER 4118X-MD5 Dielectric Resonator,
  • EN 4118X-MD4 Dielectric Resonator with the ENDOR capability.

At Q-band (34 GHz, 150 W TWT Amplifier), two resonators are available with optical access:

  • EN 5107D2 Resonator with ENDOR capability
  • EN 5106QT-2w Resonator.
