An adjustable probe assembly was designed for use with the slotted line. It has a probe travel of almost one full inch, extending the range of loads measurable by the voltage min-max power technique. After calibrating the new probe at 9.4 Gc, the system power transfer factor was de termined for the 10 Mc firing system when termi nated by a MARK 1 MOD 0 Squib. Indications are that the base of this squib is relatively lossy, and that the power transfer is on the order of .85 to .95. A rough measure of the squibs fir ing level is needed for a more detailed analysis of the data. Initial firing attempts resulted in a damaged collet. An improved design is being made up of drill rod instead of brass. An EBW test program was prepared. Application of this program to the XM6 m8 squibs will be docu mented in a special report, and no further men tion will be made in this series of reports. Author
