Production Engineering Measure for High Range Geiger Mueller Tube.

摘要

This program is an investigation of the proper techniques employed to provide stable,predictable performance GM tubes for use as the high range detector of the AN/VDR-1. The techniques include special cathode and anode surface treatment to prevent secondary emissions and resultant spurious counts (instability). Five groups of engineering test samples have been manufactured. Testing on the fourth group has been completed during this reporting period. From all indications the tests prove the units to be completely stable and meet all the requirements of the specification. A study in conjunction with ECOM group at Ft. Monmouth is being conducted on the cathode surface.
