A block-diagram of the fast scan EPR system configuration is shown on Figure 1.In order to achieve the fast field sweep necessary for accelerated fast scan EPRI (FS-EPRI) acquisition, the system utilizes a separate water-cooled primary magnetic field electromagnet and fast low inductance sweep coil placed at the center of the primary magnet. Rapid re-housing is a primary solution for ending homelessness. It has been demonstrated to be effective in getting people experiencing homelessness into permanent housing and keeping them there. By connecting people with a home, they are in a better position to address other challenges that may have led to their homelessness, such as …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 5 T 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 much longer than 5 … Presented in this paper is the demonstration of rapid scan (RS) EPR imaging implemented at 800 MHz. Generation of stable magnetic scan waveforms is critical for the RS method. A digital automatic scan control (DASC) system was developed for sinusoidal magnetic field scans. DASC permits tight control of both amplitude and phase of the scans. Rapid scan EPR means that transition through resonance occurs in a time that is short relative to electron spin relaxation times. This causes oscillation in the recorded signal. The slow scan signal can be recovered by deconvolution [1], provided that the excitation of the spin system produces a linear response [1], [3].

A crossed-loop (orthogonal mode) resonator (CLR) was constructed of fine wire to achieve design goals for rapid scan in vivo EPR imaging at VHF frequencies (in practice, near 250 MHz).
