A simple, inexpensive procedure is described for calibrating a silicon drift detector‐based PIXE system the analysis of geological and other “thick‐target” materials. It rests on use single element, chemical compound, National Institute Standards Technology multielement standards. Much less effort has been focussed impact mass attenuation coefficients PIXE's analytical accuracy than ionization cross sections fluorescence yields. The calibrated enables us to investigate effects inserting...
Grain size is an important consideration in the determination of bulk chemistry Martian rocks and unconsolidated materials situ by alpha particle X‐ray spectrometer (APXS), deployed on NASA‐led Mars Science Laboratory mission. We used 2.5 MeV protons to emulate particle‐induced emission (PIXE) branch (5 alphas) APXS. Seven polished rock slabs (igneous sedimentary), ranging from fine‐ coarse‐grained, were analyzed PIXE their original form, then milled powders pressed into pellets for further...
Abstract Limited types of radioactive molecules (RM) can be made inside hot-cavity targets at ISOL facilities like TRIUMF. However, extreme conditions in these present formidable unsolved challenges to efficient production and delivery RM’s. Here we propose using RFQ gas-reaction cells produce RM from ion beams (RIB) by room temperature RIB-gas chemical reactions eV energies. Two options are possible: (1) an reaction cell (IRC) that is a linear guide used as ‘on-line source’, (2) the ARIEL...
In this study, we investigated the employment status of recent University Ottawa physics MSc and PhD graduates, finding that 94% graduates are either employed or pursuing further education one year post-graduation. Our database was populated from public online repository theses submitted between academic years 2011 to 2019, with information collected in 2020 professional social media platform LinkedIn. results highlight primarily find quickly their field most academia physics-related...
Abstract Two-dimensional radiofrequency quadrupole (RFQ) ion guides are versatile tools that used over a wide range of energies. Properly tuned, they can provide an ideal environment for ion-molecule chemistry to proceed by allowing thermalized ions react on-line with gaseous reactants. We exploit this capability in the Ion Reaction Cell (IRC), RFQ-based system designed form radioactive molecules (RM) from beams (RIB). Functionally, IRC accepts RIB produced upstream isotope separation (ISOL)...
