A CRYOCOOLER CAPABLE OF OPERATING UNDER EXTREMELY HIGH ACCELERATION LEVELS IS PROPOSED. THE CRYOCOOLER USES THE LINDE-HAMPSON CYCLE, AND CAN REACH APPROXIMATELY 80 KELVIN. MULTI-STAGE UNITS, TO REACH LOWER TEMPERATURES, ARE ALSO POSSIBLE.

NOVEL, HIGH PERFORMANCE SPATIAL LIGHT MODULATORS (SLM) ARE BEING DEVELOPED FROM ARRAYS OF FERROELECTRIC LIQUID CRYSTAL (FLC) LIGHT VALVES. THE FLC TECHNOLOGY ALLOWS SIMPLE, ECONOMICAL FABRICATION OF SLMS WITH A LARGE NUMBER OF ELEMENTS THAT CAN BE EASILY ADDRESSED EITHER ELECTRONICALLY OR OPTICALLY. PERFORMANCE FEATURES INCLUDE SUBMICROSECOND WRITE TIMES, HIGH OPTICAL THROUGHPUT, HIGH CONTRAST, AN ...

THE ACQUISITION OF POST BOOST PHASE VEHICLES AND/OR INDIVIDUAL REENTRY VEHICLES BY AN INFRARED SENSOR ON BOARD A SMALL G HARDENED PROJECTILE WHICH SUBSEQUENTLY HOMES ON AND IMPACTS ITS TARGET OFFERS AN ATTRACTIVE APPROACH FOR REENTRY VEHICLE KINETIC ENERGY KILL. THE ACQUISITION, TRACKING, DISCRIMINATION AND GUIDANCE FUNCTIONS REQUIRED OF SUCH AN IR SENSOR RESULT IN A NUMBER OF CRITICAL ISSUES. THE ...

THE DEVELOPMENT OF HIGH POWER, HIGH REPETITION RATE CLOSING SWITCHES HAS RECENTLY BECOME IMPORTANT FOR MANY PULSED POWER APPLICATIONS. HISTORICALLY, HIGH REPETITION RATE SWITCHES FOR PULSED POWER APPLICATIONS HAVE EITHER BEEN SPARK GAPS OR THYRATRONS. THYRATRONS HAVE HIGH REPETITION RATES, BUT ARE LIMITED TO LOW VOLTAGES AND LOW CURRENT. CONVERSELY, SPARK GAPS CAN CARRY HIGH CURRENTS AND STAND-OFF ...

MANY OF THE SYSTEMS FOR SDI INVOLVE PULSE POWER AND HIGH VOLTAGE SYSTEMS, INCLUDING LASERS, PARTICLE BEAM ACCELERATORS, AND RAILGUNS. ONE OF THE SIGNIFICANT PROBLEMS YET TO BE SOLVED IN DEVELOPING OPERATIONAL SDI SPACECRAFT IS THE MANAGEMENT OF ELECTRIC FIELDS WITHIN THE SPACECRAFT, THE PRIMARY WEAPON SYSTEM, AND ITS POWER SUPPLY AND CONDITIONING EQUIPMENT. THE ELF CODES UNIQUELY HAVE THE ABILITY ...
