Study of multicharged heavy ion generation from CO2 laser-produced plasma
The results of lead ion generation with charge state from Pb10+ to Pb35+ from laser-heated plasma are presented. CO2 lasers producing 10.6-μm wavelength radiation at power densities in the range 4.1011-6.1014 W/cm2 in TBKI and CERN were used. Results of detailed numerical simulations presented in the paper are in good agreement with the experimental data. Work done in collaboration with CERN, ITEP, and TBKI was aimed at the specification of requirements for a laser system that will be able to drive an ion source for the hadron collider (LHC) at CER
Advances of dense plasma physics with particle accelerators
High intensity particle beams from accelerators induce high energy
density states in bulk matter. The SIS-18 heavy ion synchrotron at GSI now
routinely delivers intense Uranium beams that deposit about 1 kJ/g of
specific energy in solid matter, e.g. solid lead. Due to the specific nature
of the ion-matter interaction a volume of matter is heated uniformly with
low gradients of temperature and pressure in the initial phase, depending on
the pulse structure of the beam with respect to space and time. The new
accelerator complex FAIR (Facility for Antiproton and ion Research) at GSI
as well as beams from the CERN large hadron collider (LHC) will vastly
extend the accessible parameter range for high energy density states. One
special piece of accelerator equipment a superconducting high field dipole
magnet, developed for the LHC at CERN is now serving as a key instrument to
diagnose the dense plasma of the sun interior plasma, thus providing an
extremely interesting combination of accelerator physics, plasma physics and
astro-particle physics
