(ed.): Advanced EPR: Application in Biology and Biochemistry. Selected examples indicating the performance of the 94 GHz CW/FT-EPR and ENDOR systems are shown. The concerted action of these two devices results in a pulse EPR sensitivity equal or higher than in CW-EPR. The E680 FT-EPR system utilizes the PatternJet pulse programmer and the SpecJet high-speed transient signal averager. A broad-band setup is used for other nuclei. The ENDOR probe features a tuned circuit for 1H nuclei allowing an RF π-pulse of 8 μs with a 200 W amplifier. The room-temperature coil has a 800 G sweep range around the persistent field of the main magnet.

The main coil can be swept over the full range from 0 to 6 T. The magnet system consists of a 6 T split-coil superconducting magnet and a water-cooled room-temperature coil. In pulse mode the power is sufficient for a π/2 pulse of 100 ns at a resonator Q-value of 3000. The W-band bridge can be driven by a CW- or pulse-IF unit and delivers a microwave power of 5 mW at 94 GHz.

The spectrometer design is based on a heterodyne microwave bridge using an X-band intermediate frequency (IF), a hybrid magnet system, a variable-temperature, top-loading TeraFlex probehead with a TE 011 cavity as well as the ELEXSYS-line digital electronics and the Xepr software package. The design and performance of the first commercial 94 GHz continuous-wave (CW-)/Fourier transform (FT-) EPR and ENDOR spectrometer are described.
