Equipment description:

This system is used for electron spin resonance (ESR) and radical electron sensing.

ESR is used to study the couplings between electrons and nuclear spins. Continuous wave ESR (CW-ESR) is performed under continuous microwave bombardment from a nearby source. The microwave frequencies used in experiments can be tuned to match the Zeeman energy gap in a two-level system.

The system consists of a large electromagnet pair that generates a consistent field (up to 6 kG) across the sample space, an X-band microwave source, and a liquid helium cryostat capable of holding samples at room temperature down to cryogenic temperature.

System features and options:

  • large electromagnet pair (up to 6 kG field)  
  • X-band microwave source
  • Liquid Helium (LHe) cryostat
