“…A new approach has recently been proposed to study this important field of research. The main idea in this proposed technique is to create large samples of HED matter with fairly homogeneous physical conditions by isochoric and uniform heating of matter using intense ion beams (Tahir et al, 2002a(Tahir et al, , 2000b(Tahir et al, , 2001a(Tahir et al, , 2001b(Tahir et al, , 2003b(Tahir et al, , 2005b(Tahir et al, , 2005cPiriz et al, 2002, Termporal et al, 2003Lopez cela et al, 2006;Hoffmann et al, 2005).…”

High energy density physics problems related to liquid jet lithium target for Super-FRS fast extraction scheme

The new international facility for antiproton and ion research (FAIR), at Darmstadt, Germany, will accelerate beams of all stable isotopes from protons up to uranium with unprecedented intensities (of the order of 10 12 ions per spill). Planned future experiments include production of exotic nuclei by fragmentation/fission of projectile ions of different species with energies up to 1.5 GeV/u at the proposed super conducting fragment separator, Super-FRS. In such experiments, the production target must survive multiple irradiations over an extended period of time, which in case of such beam intensities is highly questionable. Previous work showed that with full intensity of the uranium beam, a solid graphite target will be destroyed after being irradiated once, unless the beam focal spot is made very large that will result in extremely poor transmission and resolution of the secondary isotopes. An alternative to a solid target could be a windowless liquid jet target. We have carried out three-dimensional numerical simulations to study the problem of target heating and propagation of pressure in a liquid Li target. These first calculations have shown that a liquid lithium target may survive the full uranium beam intensity for a reasonable size focal spot.

“…This shows that a substantial progress in the technology of high intensity bunched beams is required to achieve ion beam ICF. However, theoretical work that includes sophisticated two-and three-dimensional numerical simulations as well as analytic modeling [15][16][17][18][19][20][21][22][23][24][25][26][27][28] has shown that one can carry out very useful work in the field of high energy density ͑HED͒ physics using the existing ion beam facilities and those which will be available in the foreseeable future.…”

Generation of warm dense matter and strongly coupled plasmas using the High Radiation on Materials facility at the CERN Super Proton Synchrotron

et al. 2009

A dedicated facility named High Radiation on Materials ͑HiRadMat͒ is being constructed at CERN to study the interaction of the 450 GeV protons generated by the Super Proton Synchrotron ͑SPS͒ with fixed solid targets of different materials. The main purpose of these future experiments is to study the generation and propagation of thermal shock waves in the target in order to assess the damage caused to the equipment, including collimators and absorbers, in case of an accident involving an uncontrolled release of the entire beam at a given point. Detailed numerical simulations of the beam-target interaction of several cases of interest have been carried out. In this paper we present simulations of the thermodynamic and the hydrodynamic response of a solid tungsten cylindrical target that is facially irradiated with the SPS beam with nominal parameters. These calculations have been carried out in two steps. First, the energy loss of the protons is calculated in the solid target using the FLUKA Nucl. Sci. Eng. 123, 169 ͑1996͔͒, which is based on a Godunov-type numerical scheme. The transverse intensity distribution in the beam focal spot is Gaussian. We consider three different sizes of the focal spot that are characterized by standard deviations, = 0.088, 0.28, and 0.88 mm, respectively. This study has shown that the target is severely damaged in all the three cases and the material in the beam-heated region is transformed into warm dense matter including a strongly coupled plasma state. This new experimental facility can therefore also be used for dedicated experiments to study high energy density matter.

“…In the former case, the bunch length will be on the order of 50-100 ns, while in the latter case, one will have a quasi-uniform beam power.

Extensive numerical simulations have been carried out to design a viable solid graphite wheel shaped production target for the super conducting fragment separator experiments (Super-FRS) at the future Facility for Antiprotons and Ion Research (FAIR) using an intense uranium beam. In this study, generation, propagation and decay of deviatoric stress waves induced by the beam in the target, have been investigated. Maximum beam intensities that the target can tolerate using different focal spot sizes that are determined by requirements of good isotope resolution and transmission of the secondary beam through the fragment separator, have been calculated. It has been reported elsewhere that the tensile strength of graphite significantly increases with temperature. To take advantage of this effect, calculations have also been done in which the target is preheated to a higher temperature, that in practice can be achieved, for example, by irradiating the target with a defocused ion beam before the experiments are performed. We report results of a few examples using an initial temperature of 2000 K. This study has shown that employing such a configuration, one may use a solid graphite production target even for the maximum intensity of the uranium beam (5 Â 10 11 ion per bunch) at the Super-FRS.
