Report on December 2003 Beamtime Experiment at HHT: Near-Critical HED States of Lead Generated by Intense Uranium Beam
نویسندگان
چکیده
This paper presents a preliminary report on a recent beamtime experiment on investigation of heavy-ion-beam generated high-energy-density (HED) matter. The experiment has been performed at the HHT experimental area of GSI on 11–17.12.2003. Goals of the experiment. Main goals of this experiment were commissioning of a new multi-channel pyrometer for temporally resolved temperature measurements, improvement of transport, final focusing and diagnostics of full-intensity uranium beams and experimental test of a novel target design as well as of a few ideas on target diagnostics. Eventually, the experiment could also provide new data on thermodynamic properties and hydrodynamic response of lead in HED states. Since lead is one of the few metals which HED states near the critical point have been previously investigated in shock wave experiments [1, 2], it has been taken as a target material in order to validate the usefulness of the HIHEX method [3] for HED research and to benchmark the obtained experimental data.

Simulations of High-Energy-Density Physics Experiments at HHT Using SIS18 Uranium Beam
This contribution presents numerical simulations of two recent High Energy Density (HED) physics experiments carried out at the GSI HHT experimental area using the SIS18 uranium beam. In one experiment, a solid lead target has been used while in the other case, a solid tungsten target has been considered. Our simulations show that with the existing beam parameters, one can achieve critical temp...
متن کاملInfluence of focal length and beam rigidity on final focusing at HHT
For future experiments on investigation of high-energydensity (HED) matter at GSI where an intense heavy ion beam and a petawatt laser beam from PHELIX will be used simultaneously, a new vacuum target chamber is required. Due to dimensions of the laser guiding and focusing optics, the new chamber has to be considerably larger than the presently installed at the HHT. It may therefore be necessar...

متن کاملTemperature measurement of high-energy-density matter generated by intense heavy ion beam
Intense heavy ion beams are an excellent tool to create large-volume samples of high energy density (HED) matter with fairly uniform physical conditions. Experimental study of matter under extreme conditions of density, temperature and pressure is of considerable interest to fundamental research in the fields of plasma physics, atomic physics, astrophysics, geophysics as well as for the inertia...
متن کاملSimulations of Recent Heavy Ion Beam Matter Heating Experiments at GSI
In December 2003, the SIS-18 delivered a 350 MeV/u intense uranium beam and a record high intensity of more than 4 × 10 particles was achieved. The beam focal spot was elliptic while the beam power profile along the radial direction was Gaussian with a (FWHM)x = 0.85 mm and (FWHM)y = 1.6 mm. The experimentally measured temporal beam power profile is shown in Fig.1 which is very similar to a Gau...
