Abstract : The objective was to develop a method of detecting fires and explosions using radiation in the ultraviolet below 2900 A. Experiments were carried out to determine the best metal photocathode to be used in a biplanar structure of quartz construction to produce current amplification by electron multiplication in a hydrogen gas discharge. Experiments leading to a choice of molybdenum are described and the operation characteristics of test vehicles and final devices both evacuated and gas filled are described. Experimental demonstrations of the feasibility of the technique used are also discussed. The device was found to operate successfully at temperatures up to 590 degrees C.
