Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a sheet cavity resonator for electron spin resonance enhanced in transmittance of high frequency modulation magnetic field suitable for an external modulation system. SOLUTION: This cavity resonator 10 of X-band rectangular parallelepiped TE102mode is closed at one end with a copper plate 12 and has a flange part 20 at the other end to connect a guide plate 16 having a connecting hole 14, to a waveguide 18, wherein a cavity length L is equal to the intra-tube wavelength of microwave. Both side face cavity walls (E-faces) of the cavity resonator 10 are provided with groove parts 24, 26, and the H-faces of the cavity resonator 10 are provided with insertion holes 22, 22 for inserting a measuring sample tube. The cavity wall thickness t1of the groove parts 24, 26 is set to about the thickness of skin effect of modulation frequency. Magnetic field modulation coils not shown in the figure are embedded in the groove parts 24, 26. COPYRIGHT: (C)2005,JPO&NCIPI |
