RESEARCH AND DEVELOPMENT LEADING TO PERFECTION OF INSTRUMENTATION OF ELECTRO-EXPLOSIVE DEVICES
Abstract
Measurements of resistivity and thermoelectric power of tellurium films as a function of thickness, temperature and age are reported. Junction properties of tellurium with other materials were investigated. Two methods for measurement and control of vacuum deposition rate and film thickness and an improved vacuum deposition techniques are described. Techniques for making thin films for substrates are discussed. Comprehensive tests of bismuth-tellurium thermocouples were made and results are reported. Preliminary estimates of thermal properties of vacuum deposited thermocouples were made and thermocouple responses to step inputs of current in the Mk 1 squib were calculated. Progress of investigations of using both photoconductors and thermocouples to instrument EED's, reducing time response of thermocouples electronically and applying other types of detectors to instrumenting EED's is reported.
