The Rapid scan EPR signal is conventionally recorded as the upfield scan immediately following the digitizer trigger, but inverted placement of the coils in the B 0 field can lead to the first signal after the trigger being the downfield scan. Switch SW2 provides a way to correct for this without remounting the coils.In rapid frequency scan EPR with triangular scans, sufficient time must be allowed to insure that the magnetization in the x, y plane decays to baseline at the end of the scan, which typically is about 5T(2) after the spins are excited. To permit relaxation of signals excited toward the extremes of the scan the total scan time required may be ...

Further improvement in signal-to-noise per unit time is expected for higher duty cycles.This article celebrates the 80th birthday of Professor Gareth Eaton and his contributions to low-field EPR, especially rapid-scan EPR.

Rapid Scan EPR Workshop. 2013(July). DU EPR Center, University of Denver. CW EPR measures the signal in an equilibrium state with implied limitations on how much power can be delivered, or how fast an acquisition can be performed. In rapid-scan EPR the signal is detected directly, and unlike conventional slow-scan CW EPR, magnetic field modulation and phase-sensitive detection at the modulation frequency are not used. Instead, the magnetic field is scanned through the EPR resonance many times per second, and the absorption and dispersion signals are recorded. ...A recently described modular rapid-scan (RS) EPR imaging system 3 was used.
