5 WE PROPOSE TO DEVELOP A PASSIVE AND ACTIVE SOURCE NEUTRON AND GAMMA-RAY SPECTROMETER TO CHARACTERIZE THE ABUNDANCE OF NEARSURFACE HYDROGEN AND ROCK-FORMING ELEMENTS ON A VARIETY OF SPACECRAFT MISSIONS TO PLANETARY BODIES MOON, MARS, NEOS, COMETS. THE INSTRUMENT INITIALLY AT TRL-2 WILL USE A NEW TYPE OF SCINTILLATOR, CS2YLICL6:CE CLYC. CLYC IS SELF-ANNEALING AT ROOM TEMPERATURE AND PROVIDES BOTH HIGH EFFICIENCY DETECTION OF NEUTRONS AND EXCELLENT ENERGY RESOLUTION FOR GAMMA-RAYS. THE PROPOSED WORK WILL INVESTIGATE THE USE OF A CLYC SCINTILLATOR WITH A COSMIC-RAY BACKGROUND SOURCE AS WELL AS WITH AN ACTIVE PULSED NEUTRON GENERATOR PNG SOURCE OF NEUTRONS FOR GEOCHEMICAL ANALYSIS. OUR GOAL IS TO PROGRESS THE OVERALL INSTRUMENT PACKAGE DETECTOR AND PNG TO TRL-4. THE ABILITY OF CLYC TO DETECT BOTH NEUTRONS AND GAMMA-RAYS WITH A PHOTOMULTIPLIER TUBE HAS BEEN DEMONSTRATED VIA A PREVIOUSLY AWARDED NASA SBIR TO RMD, THUS WE ASSERT CLYC AT TRL-3. THE USE OF CLYC WITH A PNG IS AT TRL-2, AND OUR PROPOSAL WILL DEVELOP TIMING-BASED ELECTRONICS FOR THE COUPLED SYSTEM AND PERFORM TESTING IN A LABORATORY ENVIRONMENT, RESULTING IN AN OVERALL INSTRUMENT AT TRL-4.
