A new high power (~1 kW) quasi-optical W-band (94 GHz) spectrometer (HiPER) is now available for continuous wave and pulsed EPR measurements. Its high power enables generation of short pulses with large excitation bandwidths, leading to enhanced sensitivity for pulsed EPR including DEER (~two orders of magnitude improvement over conventional X-band spectrometers).
HiPER’s unique quasi-optical design also allows for large area, non-resonant sample holders that exhibit increased concentration sensitivity for CW EPR relative to commercial W-band instruments.
