Abstract A method of producing small but usable numbers of very heavy ions in a tandem Van de Graaff accelerator, having energies up to 120 MeV, will be described in detail. Experiments with these ions have included studies of the responses of various types of Si detectors and studies of the stopping powers of several elements for heavy ions.

Heavy ion experiments at the relativistic heavy ion collider
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2002Abstract Heavy Ion experiments at the Relativistic Heavy Ion Collider at Brookhaven National Laboratory are designed to search for signatures of quark-gluon plasma and enhance our understanding of the behaviour of strongly interacting matter under extreme conditions. RHIC, as the first dedicated heavy ion collider facility, can collide Au–Au beams at

Heavy Ion Interaction Experiments with Plasmas
Physica Scripta, 1999High current discharges generating a fully ionized hydrogen plasma and a high energy Nd:glass laser system (100 J, 15 ns) to produce a high density carbon plasma were used to study the interaction processes of heavy ions with ionized matter. The energy loss and charge state distribution of the projectile ions have been measured.

A calorimeter for relativistic heavy-ion experiments
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1989Abstract An iron-scintillator sampling calorimeter is described for measurement of the energy of projectile-like fragments and forward reaction products from interactions of 13.6 GeV/nucleon heavy ions with complex nuclei. Studies of the response of this device to charge- and mass-identified ions from 1 H to 28 Si indicate good linearity over the ...

Below-cutoff ions in the heavy ions in space experiment
Advances in Space Research, 1995In January 1990, the Long Duration Exposure Facility (LDEF) spacecraft was retrieved after nearly 6 years in space in a 28.4 deg orbit at a mean altitude of 476 km. Onboard LDEF was NRL's Heavy Ions In Space (HIIS) experiment, comprising large thick stacks of plastic track detectors with a total collecting power of 2.0 sq m-sr.

J-PARC Heavy Ion project (J-PARC-HI) is a future fixed target experiment to study the properties of the dense matter created by the heavy-ion collisions with 1–12[Formula: see text]AGeV/[Formula: see text] at J-PARC. This project aims to search for the QCD phase boundary and its critical endpoint and to study the equation of state of the dense matter ...

Low energy ions in the heavy ions in space (HIIS) experiment on LDEF
Advances in Space Research, 1996We present data from the Lexan top stacks in the Heavy Ions In Space (HIIS) experiment which was flown for six years (April 1984-Jan 1990) onboard the LDEF spacecraft in 28.5 degrees orbit at about 476 km altitude. HIIS was built of passive (i.e. no timing resolution) plastic track detectors which collected particles continuously over the entire ...

Clinical experience and expectations with helium and heavy ion irradiation
International Journal of Radiation Oncology*Biology*Physics, 1977Abstract In order to conduct a trial of heavy ion beams, a collaborating group of radiotherapists, radiobiologists and biophysicists (Bay Area Heavy Ion Association) has been organized under the aegis of the Lawrence Berkeley Laboratory. In designing a clinical trial starting with helium ion and progressing to heavy-ion radiotherapy as soon as ...

RICH detectors in heavy ion experiments
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1996Abstract The latest design choices and performance for the major RICH detectors employed in ultrarelativistic heavy ion experiments are reviewed in the light of their potential physics programmes. Perspectives in the planned experiment ALICE at LHC, with a RICH detector based on recent progress in highly efficient solid CsI photocathodes, are also ...

Nonmetallic targets for heavy ion experiments
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1989Abstract In heavy ion experiments the resolution often deteriorates due to irradiation damage. This problem can especially be observed with targets of chemically reactive metals. Such target deterioration can be minimized if the targets can be prepared in a chemically stable form. Techniques of preparing such stable compound targets will be described
