Abstract
An rf magnetic field pulse generator for generating an rf magnetic field pulse for use in an NMR investigation. The generator includes two arms connected in parallel between a pair of input terminals, each arm having two serially connected solid-state switches, a transmitter coil connected between output terminals defined between each pair of serially connected solid-state switches respectively, the transmitter coil being adapted to transmit the magnetic field pulse in response to an alternating rf signal at the output terminals, a power source connected to one or both input terminals, and a controller adapted to alternatively operate a respective switch in each arm at a required radio frequency in use whereby the power source is connected with alternating polarity across the transmitter coil and generates an alternating rf signal at the output terminals.
