Abstract : The work reported during the report period includes: (1) the adoption of a 'standard' pellet design to use as a control for additional experiments. (2) the evaluation of pellet design experiments performed during the second quarter. (3) the optimization of the glassing process to yield acceptable devices. (4) the replacement of the copper lead wire material with copper alloy lead wire to obtain reliable welding to the device slugs. (5) results from the A 13 matrix testing through the 1000-hour readout. (6) the presentation of the Eyring Model for expressing failure rates. (7) modification of the proposed device specification. (8) use of a new switching speed circuit to better define recovery time. (9) the delivery of the Third Engineering Samples.
