Abstract

A pulsing circuit to permit the use of a conventional low-pressure “Nester” hydrogen arc as an ultraviolet stimulating source for luminescence studies is described. The pulse duration may be varied from about 5 msec to 30 μsec with a repetition rate of 60 per second. There is no perceptible variation of the light form from pulse to pulse. The rise time of the pulses is 20 μsec and the fall time, 0.3 μsec. The pulsing circuit is assembled from conventional electronic components and contains no critical high-frequency circuits. The inherent spectral range and reliability of operation of the Nester lamp are maintained and the unit may be easily switched to dc operation. The use of this source in kinetics measurements is discussed briefly.
