“…Some of the diagnostic instruments installed for the investigation on thermophysical properties of metallic targets in HED/WDM states [1] have also been used for beam diagnostics purposes, in particular -a fast sixchannel radiation pyrometer [5]. The achromatic light collection optics of the pyrometer is installed inside the target chamber on a 3-axis motorized support perpendicular to the beam axis.…”

“…At the Gesellschaft für Schwerionenforschung (GSI), Darmstadt, Germany intense beams of energetic heavy ions are used to generate high-energy-density (HED) states in matter, or so-called warm dense matter (WDM), by their impact on solid targets [1][2][3][4][5][6][7]. For these experiments, a detailed knowledge of the spatial and temporal distributions of the ion beam intensity at the target position is essential.…”

Beam‐induced fluorescence of dense gas targets has been studied for its application to measure the transverse intensity distribution of energetic focused heavy ion beams. Mechanisms of light emission are discussed on the basis of measured wavelength‐ and time‐resolved light emission of argon. Gas pressures from 10 mbar up to 1 bar have been used. Transverse beam intensity profiles of 200 – 400 AMeV 238U pulses from the heavy ion synchrotron SIS‐18 at the Gesellschaft für Schwerionenforschung, Darmstadt, Germany with up to 5 · 109 particles per pulse focused to a sub‐millimeter spot have been recorded with argon and helium as target gases. Beam profiles recorded at the ArII lines by an optical filter resulted in the narrowest, most realistic beam diameters. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

“…This area is equipped with a strong final focusing system, diagnostics for intense, submicrosecond ion pulses and a vacuum target chamber. A comprehensive experimental setup for WDM 01011-p. 4 IFSA 2011 experiments has been developed and built up throughout the past decade [19,20,[25][26][27][28][29][30][31]. The main aims of the WDM experiments performed at the HHT area of GSI were commissioning of recently developed diagnostic instruments and methods for the future HED physics experiments at FAIR; tests of different beam-target configurations for EOS studies; optimization of transport, focusing and diagnostics of intense heavy ion beams; obtaining new data on thermo-physical properties and hydrodynamic response of various materials in HED states near boiling curve, two-phase liquid-gas and the critical point regions.…”

Abstract. The Facility for Antiproton and Ion Research in Europe (FAIR) will provide worldwide unique accelerator and experimental facilities allowing for a large variety of unprecedented frontier research in extreme state of matter physics and applied science. Indeed, it is the largest basic research project on the roadmap of the European Strategy Forum of Research Infrastructures (ESFRI), and it is cornerstone of the European Research Area. FAIR offers to scientists from the whole world an abundance of outstanding research opportunities, broader in scope than any other contemporary large-scale facility worldwide. More than 2500 scientists are involved in setting up and exploiting the FAIR facility. They will push the frontiers of our knowledge in plasma, nuclear, atomic, hadron and applied physics far ahead, with important implications also for other fields in science such as cosmology, astro and particle physics, and technology. It includes 14 initial experiments, which form the four scientific pillars of FAIR. The main thrust of intense heavy ion and laser beam-matter interaction research focuses on the structure and evolution of extreme state of matter on both a microscopic and on a cosmic scale.

“…We have conducted an experiment at the HHT target station at GSI [12,13]. The experiment studied the effect of pore size on target behavior using existing diagnostics, for example by measuring the target temperature as a function of pore size and compare with model predictions of the physics of porous targets.…”

The US heavy ion fusion science program has developed techniques for heating ion-beam-driven warm dense matter (WDM) targets. The WDM conditions are to be achieved by combined longitudinal and transverse space-charge neutralized drift compression of the ion beam to provide a hot spot on the target with a beam spot size of about 1 mm, and pulse length about 1-2 ns. As a technique for heating volumetric samples of matter to high energy density, intense beams of heavy ions are capable of delivering precise and uniform beam energy deposition dE/dx, in a relatively large sample size, and the ability to heat any solid-phase target material. Initial experiments use a 0.3 MeV K+ beam (below the Bragg peak) from the NDCX-I accelerator. Future plans include target experiments using the NDCX-II accelerator, which is designed to heat targets at the Bragg peak using a 3-6 MeV lithium ion beam. The range of the beams in solid matter targets is about 1 micron, which can be lengthened by using porous targets at reduced density.We have completed the fabrication of a new experimental target chamber facility for WDM experiments, and implemented initial target diagnostics to be used for the first target experiments in NDCX-1. The target chamber has been installed on the NDCX-I beamline. The target diagnostics include a fast multi-channel optical pyrometer, optical streak camera, VISAR, and high-speed gated cameras. Initial WDM experiments will heat targets by compressed NDCX-I beams and will explore measurement of temperature and other target parameters. Experiments are planned in areas such as dense electronegative targets, porous target homogenization and two-phase equation of state.2
