INVESTIGATING RADIATION PARTICLE INTERACTIONS WITH SILICON USING ANALYTICAL AND EXPERIMENTAL METHODS THE DEVELOPMENT OF A HIGH-ENERGY HEAVY ION BOARD LEVEL SINGLE EVENT EFFECT (SEE) GROUND-BASED TEST METHOD AND CAPABILITY, THE VARIABLE DEPTH BRAGG PEAK (VDBP) METHOD AT NSRL, IS THE PRIMARY GOAL OF THIS EFFORT. THIS METHOD ALLOWS TESTING OF COMPLEX PARTS WITH EMBEDDED SENSITIVE VOLUMES THAT CANNOT BE TESTED WITH LOW ENERGY HEAVY IONS OR PROTONS. THIS DEVELOPMENT ENTAILS WORK WITH THE NASA SPACE RADIATION LABORATORY (NSRL) PERSONNEL TO DEVELOP INSTRUMENTATION, PROCEDURES AND SOFTWARE TO MAKE RADIATION EFFECTS TESTING WITH RELATIVISTIC HEAVY IONS USING THE VDBP AND OTHER METHODS ROUTINE AND EFFICIENT. WORK TO RESOLVE AN APPARENT ION SPECIES DEPENDENCE OBSERVED FOR ONE PART, THE AEROFLEX RADHARD BY DESIGN 4M SRAM X32 UTBR128K32 DURING FEASIBILITY DEMONSTRATION MEASUREMENTS WITH THE VDBP METHOD. WORK WITH NASA/JSC TO PERFORM TESTS OF DEVICES TO DEMONSTRATE THAT OTHER RADIATION EFFECTS THAN SINGLE EVENT UPSETS/TRANSIENTS, SUCH AS LATCH-UP, BURN OUT AND GATE RUPTURE, CAN BE OBSERVED WITH THE VDBP METHOD. WORK WITH NSRL, BNL, NASA AND OTHER INTERESTED PARTIES TO DEVELOP AN ADMINISTRATIVE STRUCTURE TO MAKE THE NSRL RADIATION EFFECTS IN MICROELECTRONICS TEST CAPABILITY ROUTINELY AVAILABLE TO THE RADIATION EFFECTS COMMUNITY TASK 1 THE CONTRACTOR SHALL ADVISE AND ASSIST IN DEVELOPMENT AND DEMONSTRATION OF A HIGH ENERGY HEAVY ION BOARD LEVEL SINGLE EVENT EFFECT (SEE) GROUND-BASED TEST METHOD AND CAPABILITY, THE VARIABLE DEPTH BRAGG PEAK (VDBP) METHOD AT NSRL. TASK 2 - THE CONTRACTOR SHALL ADVISE AND ASSIST WITH WORK TO RESOLVE AN APPARENT ION SPECIES DEPENDENCE OBSERVED IN VDBP DEMONSTRATION EXPERIMENTS FOR ONE PART, THE AEROFLEX RADHARD BY DESIGN 4M SRAM X32 UTBR128K32. TASK 3 THE CONTRACTOR SHALL ADVISE AND ASSIST IN THE PERFORMANCE OF TESTS OF DEVICES TO DEMONSTRATE THAT THE RADIATION EFFECTS THAT THEY ARE KNOWN TO EXHIBIT IN LOW ENERGY HEAVY ION TESTS CAN BE DETECTED WITH THE VDBP METHOD.
