Time resolved energy loss spectrometry of heavy ions generating a dense plasma — •D. Varentsov1, P. Spiller2, U. Neuner2, and D.H.H. Hoffmann1,2 — 1Technische Universität Darmstadt — 2Gesellschaft für Schwerionenforschung, Darmstadt
The heavy ion synchrotron (SIS) at the GSI Darmstadt provides intense beams of
heavy ions up to uranium accelerated to energies
of the order of 300 MeV/u. Using this facility the experiments with heavy ion
beam generated dense plasmas from solid targets
are being performed at the GSI Plasma Physics group experimental area HHT. By
the use of a dispersive magnetic spectrometer tog
ether with a fast streak camera it is possible to measure time resolved energy
loss and charge state distribution spectra of th
e heavy ion beam during the whole time of generation of the plasma. Such
measurements will provide quantitative information for
understanding of the interaction phenomena between fast heavy ions and dense
plasma as well as the information about the energ
y deposition processes of heavy ions in solids and plasmas.
The spectrometer has to provide a large energy acceptance for heavy ion beams
with relatively high magnetic rigidity. Because o
f the limited spatial extension of the experimental area the spectrometer
should be also quite compact.
This work is devoted to the development of a magnetic spectrometer for plasma
physics experiments at HHT. Different approaches,
including conventional steel-dominated magnets and a fast high-current pulsed
magnets have been considered.
This work was supported by the BMBF.
