The method of Ion-Laser InterAction Mass Spectrometry (ILIAMS) offers new options for the determination 26Al by Accelerator (AMS) and improves sensitivity efficiency detection this isotope in artificial environmental samples. In ILIAMS, a laser is overlapped with ion beam during its passage through radiofrequency quadrupole cooler. Those ions electron affinity lower than energy photons are selectively neutralized photodetachment process. Because MgO that AlO, ILIAMS can suppress isobar 26Mg...
Recent major advances in Accelerator Mass Spectrometry (AMS) at the Vienna Environmental Research (VERA) regarding detection efficiency and isobar suppression have opened possibilities for analysis of additional long-lived radionuclides ultra-low environmental concentrations. These radionuclides, including 233 U, 135 Cs, 99 Tc, 90 Sr, will become important oceanographic tracer application due to their generally conservative behavior ocean water. In particular, isotope ratios U/ 236 U 137 Cs/...
ABSTRACT A setup for ion-laser interaction was coupled to the state-of-the-art AMS facility VERA five years ago and its potential applicability as a new means of isobar suppression in accelerator mass spectrometry (AMS) has since been explored. Laser photodetachment molecular dissociation processes anions provide unprecedented factors >10 10 several established isotopes like 36 Cl or 26 Al give access 90 Sr, 135 Cs 182 Hf at 3-MV-tandem facility. Furthermore, Ion-Laser InterAction Mass...

The design goal of 400 kW uranium beam in the Rare Isotope Accelerator (RIA) Driver Linac can be achieved employing a concept simultaneous acceleration two charge states. It has been undertaken to build prototype 2Q-injector RIA which includes an ECR ion source, LEBT and one-segment RFQ. project called 2Q-LEBT Facility is being developed Physics Division ANL. Currently, consists BIE-100 source. reassembly commissioning source completed. During process we redesigned manufactured few...
Fluoride molecular anions have emerged as a potential alternative to oxides for the analysis of actinides in AMS. Research at Vienna Environmental Accelerator (VERA) has focused on mixing samples prepared an Fe2O3 matrix with PbF2 situ fluoridation during sputter process. The relative formation probabilities range (oxy-)fluoride uranium, neptunium, plutonium, and americium been found be characteristic each investigated. These data can help identify isobaric interference mentioned actinides....
