INVESTIGATE EVIDENCE FOR VOLATILE RELEASE FROM AMORPHOUS RIMS. TO ATTAIN THIS OBJECTIVE SCANNING ELECTRON MICROSCOPY (SEM) AND (SCANNING) TRANSMISSION ELECTRON MICROSCOPY ((S)TEM) IMAGERY WILL BE USED TO CHARACTERIZE IMPACT MELT/VAPOR DEPOSITED RIMS ON EXPERIMENTAL AND LUNAR AND ASTEROID REGOLITH GRAINS. VOLATILES MAINLY IN THE FORM OF H RELEASED BY SPACE WEATHERING PROCESSES AND OBSERVED IN REMOTE SENSING DATA (BANDFIELD ET AL. 2018 CLARK 2009 LI AND MILLIKEN 2017 PIETERS ET AL. 2009 SUNSHINE ET AL. 2009) ARE A POSSIBLE SOURCE FOR ICES TRAPPED IN POLAR REGOLITHS (ARNOLD 1979). 2. DETERMINE WATER AND OH PRODUCTION AS A FUNCTION OF PROTON AND LASER + PROTON IRRADIATION AND LOCAL ENVIRONMENT (E.G. TEMPERATURE&COMPOSITION). THE ACCOMPLISHMENT OF THIS OBJECTIVE WILL CONSIST OF USING (S)TEM TO CHARACTERIZE SMFE AS WELL AS VESICLE SIZE AND USING VALENCE ELECTRON ENERGY LOSS SPECTROSCOPY (VEELS) TO ESTIMATE RELATIVE VOLATILE CONTENTS WITHIN AMORPHOUS RIMS PRODUCED BY 1 KEV H+ AND POTENTIALLY DESTROYED BY LASER IRRADIATION OR MICROMETEORITE IMPACTS. VEELS CAN PRODUCE RELATIVE MEASURES OF H2O PRODUCED AT A GIVEN TEMPERATURE OR BY EXTRAPOLATION LATITUDE. RESULTS FROM THESE ANALYSES WILL BE USED TO ASSESS IF THERE IS AN IDEAL TEMPERATURE/LATITUDE FOR RADIOLYTIC WATER PRODUCTION AND THE EXTENT TO WHICH IRRADIATED RIMS SERVE AS RESERVOIRS FOR SOLAR WIND PRODUCED VOLATILES AND A SOURCE FOR LUNAR ICE DEPOSITS. IRRADIATED RIMS AS VOLATILE RESERVOIRS: ONE EXPLANATION FOR THE OBSERVATION OF LUNAR H2O AND OH IS THE IN SITU FORMATION BY SOLAR WIND PROTONS (1 KEV H+) AND HIGHER MASS HE+ WHICH CONSTANTLY BOMBARD THE DAYTIME SURFACE.
