Summary on Grant Application Form |
|
X-ray spectroscopy is one of the primary ways used to study the physics of highly charged ions. High resolution crystal spectrometers and broadband semiconductor ionization detectors have been the traditional tools for these investigations. However although they have yielded many excellent results, these instruments are limited either by a poor energy resolution (solid state detector) or by a low efficiency and a narrow bandwidth (crystal spectrometer). By contrast, cryogenic X-ray microcalorimeters have high resolving power, quantum efficiency approaching 100%, and a bandwidth that spans 0.1-10 keV.W e are part of a team, also involving scientists at the Harvard-Smithsonian Center for Astrophysics (HSCA) and the National Institute of Standards and Technology (NIST), which plan to use a microcalorimeter on the Electron Beam Ion Trap at NIST to undertake a range of fundamental studies related to highly charged ions. These include (i) X-ray spectroscopy of single valence, multi-electron configurations that will test many-body relativistic atomic structure calculations, (ii) measurements of absolute electron impact excitation cross sections, (iii) neutralisation and relaxation of highly charged ions at solid surfaces. In this proposal we seek funding for UK participation in this exciting project. Specifically, we require postdoctoral support to undertake an extensive programme of atomic physics calculations for comparison with the experimental results.
