Rick has been actively involved with the cold neutron prompt gamma-ray analysis (PGAA) instrument at the NIST Center for Neutron Research since 1991 and has contributed significantly to the upgrade of this instrument. He participated significantly in the development and certification of hydrogen in Ti alloy SRMs for the aircraft industry. He has worked with users of the PGAA facility from industry, academia, and government on the analysis of hydrogen, boron, and other elements in a wide variety of materials. He is currently involved in the planning and building of a new cold neutron PGAA facility at the NCNR as well as on the development and analysis of materials for hydrogen storage. Rick has also been actively involved in radiochemical neutron activation analysis (RNAA), working on the development of procedures for measuring phosphorus, sulfur, nitrogen, and arsenic at mg/kg levels and lower. He was instrumental in the development and certification of a phosphorus implant in silicon implant SRM for the semiconductor industry. More recently he has been involved in the certification of more than 25 elements in soils, coals, and flyash by instrumental neutron activation analysis (INAA). He has authored or co-authored more than 70 peer-reviewed publications describing these activities.
