Many measurements which are presently not possible will be required to operate anticipated SDI power and weapon systems. The following are points which represent the main findings and conclusions of this study concerning the most critical metrology shortcomings and the most promising areas of metrology research: No adequate method exists for measuring high voltages and currents under space-platform conditions. Magneto- and electro-optical measurements appear promising for space applications. Improved accuracy in power measurements at high frequencies are necessary for waste-heat management. Intrinsic standards and measurement techniques (such as CARS, NQR thermometry, and Josephson junctions) should be developed for long-term measurement calibrations. The development of reliable calibration standards is critical to the long-term control of complex space systems. High-temperature, radiation-hardened sensors need to be developed for practically all parameters. Specifically the development of semiconductor devices to survive the anticipated environment on a space nuclear power platform is essential. Improved dynamic-pressure sensors and the corresponding standards for calibration need to be developed. Radiation sensors which can survive high temperatures (T greater than 2000 K) and temperature sensors which can survive high radiation fluxes are required. Electron and ion beam diagnostic devices need to be improved to be suitable for SDI applications. All sensors, support electronics, standards, and control systems must be characterized under all conditions anticipated during long-term space deployment. Most importantly, long-term calibration and reliability of sensors must be addressed either by means of improved hardware or by improved software for internal control and calibration.
