CMR 750 GHardwareCMR G is a 750 MHz NMR system based on a Magnex medium bore magnet and a console designed and constructed by the center. It has four fully equipped rf channels and is capable of lock switched deuterium decoupling. It is intended for high resolution liquid NMR studies.Console Four transmitter channels Per channel fully programable frequency modulator with sub milliHz resolution Per channel fully programable phase modulator with 0.1 degree resolution Per channel fully programable amplitude modulator with 0.05% resolution Four channel pulse programmer with 20 nsec resolution Double buffered averager Digital deuterium lock Temperature controller with 0.1 degree Celsius resolution FTS Air-jet cooler Four channel fully programable gradient waveform generator Single 10 amp gradient amplifier with protection circuitry |
