An investigation of the proper techniques employed to provide stable, predictable performance, G-M tubes for use as the high range detector of the AN VDR-1 is discussed. The techniques include special cathode and anode surface treatment to prevent secondary emissions and resultant spurious counts instability and up-dated outgassing and filling procedures to improve gas stability and reduce absorption thereby improving voltage stability. In the time period of this report a second set of engineering test samples was fabricated and filled to a starting voltage range of 430 plus or minus 10 volts. Initial tests data indicates a trend toward achieving the required critical parameter of starting voltage stability.
