FY14 Progress Report for PL12-LaserSPec SIMS-PD08: Laser Photoionization of Sputtered Neutral atoms in PNNL SIMS and Applications in Nuclear Materials and Environmental Analyses

A continuous wave (CW) Ar ion laser producing photons at 244 nm (doubled from the fundamental wavelength at 488nm) was used to ionize neutrals sputtered from representative lanthanide (neodymium oxide, Nd 2 O 3 ) and actinide (uranium oxide, U 3 O 8 ) containing materials in the modified Cameca ims-4f at PNNL.
