“…Over the past decade, extensive theoretical work has been carried out to study the problem of generating High Energy Density (HED) matter in the laboratory employing intense heavy ion beams [1][2][3][4][5]. Several experiment designs that propose generation of HED matter considering isochoric and uniform heating of solid targets as well as shock compression of matter, have been proposed.…”

“…The focal spot geometry will be circular, nevertheless, provisions are being made for an annular shaped focal spot to carry out compression experiments. An rf-wobbler is being designed to generate the latter focal spot geometry [5,6]. Earlier, another option, namely, use of a plasma lens, was considered for this purpose [7], however, this option has now been dropped.…”

Abstract. High Energy Density (HED) physics spans over numerous areas of basic and applied physics, for example, astrophysics, planetary physics, geophysics, inertial fusion and many others. During the past fifteen years, great progress has been made on the development of bunched intense particle beams that have emerged as a novel tool for studying HED physics. In this paper we present two experiment designs that have been worked out for HED physics studies at the Facility for Antiprotons and Ion Research (FAIR) at Darmstadt. This facility has entered into construction phase and will provide one of the largest and most powerful particle accelerators in the world.

“…The improvement of stability properties can be attributed to two factors. First, uniform illumination reduces the initial seeding amplitude of the RT instability [1,[11][12][13]. Second, at a given location on the target, the energy/momentum input is pulsating rapidly with time, which results in a dynamic stabilization effect on the instability .…”

Dynamic stabilization of the ablative Rayleigh-Taylor instability of a heavy ion fusion target induced by a beam wobbling system is studied. Using a sharp-boundary model and Courant-Synder theory, it is shown, with an appropriately chosen modulation waveform, that the instability can be stabilized in certain parameter regimes. It is found that the stabilization effect has a strong dependence on the modulation frequency and the waveform.Modulation with frequency comparable to the instability growth rate is the most effective in terms of stabilizing the instability. A modulation with two frequency components can result in a reduction of the growth rate larger than the sum of that due to the two components when applied separately.

“…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

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.
