Identifying both physical and chemical characteristics of Special Nuclear Material (SNM) production processes is the corner stone of nuclear forensics. Typically, processing markers are based on measuring an interdicted sample’s bulk chemical prope

Much of the recent work in the DANCE collaboration has focused on nuclides of interest to stockpile stewardship, attribution science and the advanced fuel cycle initiative. As an example, we have recently begun a program to produce high precision mea

Solid dosed tungsten-fluorine lamps have improved life compared to bromine lamps. Lamps remain clean through life. Protection of the lamp envelope from attack by fluorine is due to a passivation layer of aluminum fluoride formed by reaction of an int
