An outlook of heavy ion driven plasma research at IMP-Lanzhou

Trends in heavy ion interaction with plasma

“…As a result, the highquality heavy ion beams with large energy range become available at IMP Lanzhou, e.g., 2.8 GeV proton and 1.1 AMeV carbon ion could be provided by CSR m ; 2.0 GeV proton and 760 AMeV carbon ion could be extracted from CSR e . In the CSR m system, the new generation of electron cooler is used to improve the beam quality and then the beam momentum spread is decreased from 1.5 × 10 −3 to 5 × 10 −4 for C-U ion with energy varying from 10 to 50 MeV/u (Zhan et al, 2004, 2007Zhao et al, 2009).…”

“…The motivations are mainly listed as follows: (1) the energy deposition process of heavy ions in ionized matter is one of the most important processes of heavy-ion-driven high energy density and ICF; (2) Plasma devices could be served as an important accelerator equipment to focus ion beams (socalled plasma lens), and or to strip ion beams (so-called plasma stripper). Beside these applications, such research is also an important fundamental topic to understand the atomic processes in plasma, such as the di-electron recombination process, the radiative electron capture process, and the effective charge in Coulomb interaction process, and so on (Sigmund, 1969;Hoffmann et al, 1990;Dietrich et al, 1992;Jacoby et al, 1995;Golubev et al, 2001;Sharkov, 2001;Bock et al, 2005;Logan et al, 2005;Tahir et al, 2005;Piriz et al, 2006;Zhao et al, 2009;Teske et al, 2010;Tahir et al, 2010;Pikuz et al, 2010;Xin et al, 2010;Zhang et al, 2011).…”

High energy density physics research at IMP, Lanzhou, China

“…Email: zhaoyt@impcas.ac.cn by methods of high energy proton/ion radiography and in fast ignition of a compressed fuel. Associated investigations have been pursued with increasing intensity by major accelerator laboratories and institutions in Europe, the USA, Russia, and Japan, where significant progress has been made during the last few decades [1][2][3][4][5][6][7][8][9][10][11][12][13][14] .…”

“…Detailed introduction of the facilities has been reported elsewhere [10] . Figure 1 shows typical radiographic images of an IMP sign and a ballpoint pen, where the marginal range radiography method was used.…”

Two-dimensional quantum hydrodynamic model for the heating of a solid target using a Gaussian cluster

“…Using clusters as a ICF driver, can break through the space-charge limit of ion beam, which is helpful to achieve high heating effect. Recently, several attempts have been made to investigate the beam-matter interactions involving heavy ion (Zhao et al, 2009;Hoffmann et al, 2010), proton (Patel et al, 2003;Tahir et al, 2009a) and laser beams (Zhao et al, 2012). In particular, ICF is a promising scheme, where a target matter can be irradiated by intense ion beams or clusters, and be transformed into a plasma of high density and high temperature which can initiate fusion reactions (Deutsch, 1992;Tahir et al, 2005).…”
