摘要

The report describes the construction and operating procedure of a pulsed nuclear resonance apparatus designed to measure the spin-lattice relaxation times in alkali halide crystals at low temperatures. A description of the cryogenics is included. The transmitter is capable of producing short, fast-rising rf pulses having a broad frequency spectrum and the receiver has a short recovery time. The apparatus as a whole is stable enough to measure the long relaxation times at low temperatures.
