Bruker EMX X-band ESR
Consists of a large electromagnet pair that generates a consistent field 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.
This system is used for electron spin resonance (ESR) and radical electron sensing. Both our pulsed and continuous wave systems are equipped with liquid helium cryostats, allowing us to perform experiments at cryogenic temperature.
Electron spin resonance (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. CW-ESR can be used to study electron nuclear double resonance (ENDOR). The microwave frequencies used in experiments can be tuned to match the Zeeman energy gap in a two level system.
