The Large Hadron Collider (LHC) will operate with 7 TeV/c protons with a luminosity of 10 34 cm 22 s 21 . This requires two beams, each with 2808 bunches. The nominal intensity per bunch is 1.15 Â 10 11 protons and the total energy stored in each beam is 362 MJ. In previous papers, the mechanisms causing equipment damage in case of a failure of the machine protection system was discussed, assuming that the entire beam is deflected onto a copper target. Another failure scenario is the deflection of beam, or part of it, into carbon material. Carbon collimators and beam absorbers are installed in many locations around the LHC close to the beam, since carbon is the material that is most suitable to absorb the beam energy without being damaged. In case of a failure, it is very likely that such absorbers are hit first, for example, when the beam is accidentally deflected. Some type of failures needs to be anticipated, such as accidental firing of injection and extraction kicker magnets leading to a wrong deflection of a few bunches. Protection of LHC equipment relies on the capture of wrongly deflected bunches with beam absorbers that are positioned close to the beam. For maximum robustness, the absorbers jaws are made out of carbon materials. It has been demonstrated experimentally and theoretically that carbon survives the impact of a few bunches expected for such failures. However, beam absorbers are not designed for major failures in the protection system, such as the beam dump kicker deflecting the entire beam by a wrong angle. Since beam absorbers are closest to the beam, it is likely that they are hit first in any case of accidental beam loss. In the present paper we present numerical simulations using carbon as target material in order to estimate the damage caused to carbon absorbers in case of major beam impact.

“…This type of experiment is suitable for studying the problem of hydrogen metallization [17], [22][23][24][25], [28], [30][31][32], [35,36], [59][60][61][62][63], [64] or for creating physical conditions that are expected to exist in the interiors of the giant planets [65,66]. For this reason, this experiment is named LAPLAS (LAboratory PLAnetary Science).…”

“…This scheme generates a low-entropy compression that leads to a very high material density with a relatively low temperature. Simulations have shown that using the parameters of the SIS100 beam at the FAIR, one would achieve a hydrogen density of 1 -3 g/cm 3 , a pressure of 3 -30 Mbar and a temperature of a few thousand K. This scheme is therefore more suited to study the problem of hydrogen metallization [17], [22][23][24][25], [28], [30][31][32], [35,36], [59][60][61][62][63].…”

The forthcoming Facility for Antiprotons and Ion Research (FAIR) at Darmstadt, is going to be a unique accelerator facility that will deliver high quality, strongly bunched, well focused, intense beams of heavy ions that will lead to unprecedented specific power deposition in solid matter. This will generate macroscopic samples of High Energy Density (HED) matter with fairly uniform physical conditions. These samples can be used to study the thermophysical and transport properties of HED matter. Extensive theoretical work has been carried out over the past decade to design numerous dedicated experiments to study HED physics at the FAIR, which has provided the basis for the HEDgeHOB (High Energy Density Matter Generated by Heavy Ion Beams) scientific proposal. This work is still in progress as the feasibility studies for more experimental schemes are being carried out.Another, very important research area that will benefit tremendously from the FAIR facility, is the production of radioactive beams. A superconducting fragment separator, Super-FRS is being designed for the production and separation of rare radioactive isotopes. Unlike the HED targets, the Super-FRS production target should not be destroyed or damaged by the beam, but should remain intact during the long experimental campaign. However, the high level of specific power deposited in the production target by the high intensity ion beam at FAIR, could cause serious problems to the target survival. These HED issues related to the Super-FRS production target are also discussed in the present paper.

“…In the US, high-current low-energy accelerators are currently exploiting the plateau in dE/dX from nuclear stopping on the Neutralized Drift Compression Experiment (NDCX-I) [3] and plans are being developed to exploit deposition at the Bragg peak on an upgrade called NDCX-II. This is in contrast to the European approach at GSI using high-energy but lower current accelerators that operate near a minimum in dE/dX providing large volumes of uniform energy deposition [4,5]. Ideally the energy deposition occurs in a time that is short compared to the hydro expansion time scale, so that temperatures larger compared to the vaporization temperature can be achieved but at solid density.…”

a b s t r a c tHydrodynamic simulations have been carried out using the multi-physics radiation hydrodynamics code HYDRA and the simplified one-dimensional hydrodynamics code DISH. We simulate possible targets for a near-term experiment at LBNL (the Neutralized Drift Compression Experiment, NDCX) and possible later experiments on a proposed facility (NDCX-II) for studies of warm dense matter and inertial fusion energy-related beam-target coupling. Simulations of various target materials (including solids and foams) are presented. Experimental configurations include single-pulse planar metallic solid and foam foils. Concepts for double-pulsed and ramped-energy pulses on cryogenic targets and foams have been simulated for exploring direct drive beam-target coupling, and concepts and simulations for collapsing cylindrical and spherical bubbles to enhance temperature and pressure for warm dense matter studies.
