“…The upgraded version additionally includes thermal radiation losses from the target surface which is very important in the present type of problem [39]. We note that similar studies have previously been done for the low energy, light ion beams to be generated at the SPIRAL2, and the results are reported elsewhere [39,40]. It is to be noted that generating a high resolution three-dimensional mesh for such very thin targets is very complicated.…”

This paper presents an extensive numerical study of heating of thin solid carbon foils by 1.4 MeV=u uranium ion beams to explore the possibility of using such a target as a charge stripper at the proposed new Gesellschaft für Schwerionenforschung high energy heavy-ion linac. These simulations have been carried out using a sophisticated 3D computer code that accounts for physical phenomena that are important in this problem. A variety of beam and target parameters have been considered. The results suggest that within the considered parameter range, the target will be severely damaged by the beam. Thus, a carbon foil stripper does not seem to be a reliable option for the future Gesellschaft für Schwerionenforschung high energy heavy-ion linac, in particular, at FAIR design beam intensities.

“…It is important to emphasize that this problem involves beam-matter interaction studies, which is a very important and interesting field of research with wide applications to basic and applied physics, for example, ion-beam-driven inertial fusion [11][12][13][14] and the generation of high-energydensity (HED) matter [15][16][17][18][19][20][21][22][23][24][25]. Furthermore, development of the production targets for the generation of rare radioactive isotopes [26][27][28][29] as well as designing of targets for the stripping of energetic ions [30][31][32] also belong to this area of research.…”

A future circular collider (FCC) has been proposed as a post-Large Hadron Collider accelerator, to explore particle physics in unprecedented energy ranges. The FCC is a circular collider in a tunnel with a circumference of 80-100 km. The FCC study puts an emphasis on proton-proton high-energy and electron-positron high-intensity frontier machines. A proton-electron interaction scenario is also examined. According to the nominal FCC parameters, each of the 50 TeV proton beams will carry an amount of 8.5 GJ energy that is equivalent to the kinetic energy of an Airbus A380 (560 t) at a typical speed of 850 km/h. Safety of operation with such extremely energetic beams is an important issue, as off-nominal beam loss can cause serious damage to the accelerator and detector components with a severe impact on the accelerator environment. In order to estimate the consequences of an accident with the full beam accidently deflected into equipment, we have carried out numerical simulations of interaction of a FCC beam with a solid copper target using an energy-deposition code (FLUKA) and a 2D hydrodynamic code (BIG2) iteratively. These simulations show that, although the penetration length of a single FCC proton and its shower in solid copper is about 1.5 m, the full FCC beam will penetrate up to about 350 m into the target because of the "hydrodynamic tunneling." These simulations also show that a significant part of the target is converted into high-energy-density matter. We also discuss this interesting aspect of this study

This work presents time-dependent numerical calculations of heat generation and dissipation in targets used in high ion-beam current nuclear astrophysics experiments. The simulation is beneficial for choosing the thickness of targets, maximum ion-beam current and design setup for cooling of such targets. It is found that for the very thin target ( 27 Al(p, p), 12 C(p, p)) heat generation inside target is relatively low and a fair amount of high current (few μA)can be used without any melting issue. But in case of thick targets ( 27 Al(p, γ), 12 C(p, γ)) cooling became essential for the survival of reaction target.
