Abstract

A stable, high-intensity resonance lamp operated by a 2450 Mc/sec microwave power source has been developed which is of sufficient intensity and stability to be useful for the kinetic study of photochemical reactions. This light source has maintained a constant output (approximately 2 × 10¹⁷ quanta/sec for krypton) for times ranging from 80 h to 120 h. The optimum pressure of krypton in the lamp is 0.28 torr.
