CMR 380 JHardwareCMR J is a 380 MHz DNP-NMR spectrometer based on a wide-bore Magnex Scientific magnet (9 T) with a ±1 Tesla superconducting sweep coil. The spectrometer console, designed and constructed by the center, has two fully equiped RF channels and one microwave channel. It has low temperature capability for static (> 25 K) experiments. It is intended for dynamic nuclear polarization solid-state NMR studies. A 250 GHz gyrotron microwave source, constructed by the center, provides CW output powers of up to 25 W. Console Two transmitter RF channels Per channel fully programable frequency modulator with sub-millihertz resolution Per channel fully programable phase modulator with 0.1 degree resolution Per channel fully programable amplitude modulator with 0.5% resolution Four channel pulse programmer with 20 nsec resolution |
