Hot cell based time-of-flight mass spectrometry

Abstract

A time-of-flight mass spectrometer has been designed and is presently being installed within a radiological controlled hot cell at Argonne National Laboratory-West. Direct solid sampling is performed by laser ablation or glow discharge sputtering followed by supersonic expansion into the TOFMS source chamber. Once the atom/ion beam enters the source chamber, enhanced ionization can be accomplished by laser ionization or electron impact. An assortment of samples may be analyzed ranging from irradiated nuclear fuel elements and cladding materials to eutectic salts, radioactive waste materials and environmental samples.
