89-917 - Results of the NASA Space Radiation<br />

Laboratory Beam Studies Program at BNL<br />

The NASA Space Radiation Laboratory (NSRL) was<br />

constructed in collaboration with NASA for the<br />

purpose of performing radiation effect studies for the<br />

NASA space program. The NSRL makes use of heavy<br />

ions in the range of 0.05 to 3 GeV/n slow extracted<br />

from BNL's AGS Booster. The purpose of the NSRL<br />

beam studies program is to develop a clear<br />

underst<strong>and</strong>ing of the beams delivered to the facility, to<br />

fully characterize those beams, <strong>and</strong> to develop new<br />

capabilities in the interest of underst<strong>and</strong>ing the<br />

radiation environment in space. In this report we will<br />

describe the first results from this program.<br />

90-977 - Generation of a Femtosecond Electron<br />

Beam for Nanoscience <strong>and</strong> Nanotechnology<br />

Jinfeng Yang (RCNP, Osaka), Yang Jinfeng (ISIR, )<br />

A new S-b<strong>and</strong> femtosecond electron linear accelerator<br />

was developed in Osaka University for the study of<br />

radiation-induced ultrafast physical <strong>and</strong> chemical<br />

reactions in femtosecond time regions. The<br />

femtosecond electron accelerator was constructed with<br />

a laser driven photocathode RF gun, a linear<br />

accelerator (linac) <strong>and</strong> a magnetic pulse compressor.<br />

The RF gun was driven by a mode-locked Nd:YLF<br />

picosecond laser. The electron beam produced by the<br />

RF gun was accelerated in the linac with energy<br />

modulattion by adjusted the RF phase. The magnetic<br />

pulse compression, which was constructed with two<br />

45o-bending magnets <strong>and</strong> four quadrupole magnets, is<br />

a technique to longitudinally focus a charged beam by<br />

rotating the phase space distribution in a magnetic<br />

field. The picosecond electron pulse, which was<br />

generated in the RF gun <strong>and</strong> accelerated in the linac<br />

with energy modulation, was compressed into<br />

femtosecond by adjusted the quadrupole magnetic<br />

fields. The femtosecond electron pulse is expected for the<br />

studies of ultrafast reactions in nano-space.<br />

91-1053 - Review of ISOL-type Radioactive Beam<br />

Facilities<br />

Mats Lindroos (<strong>CERN</strong>, Geneva)<br />

The ISOL technique was invented in Copenhagen over 50<br />

years ago <strong>and</strong> eventually migrated to <strong>CERN</strong> where a<br />

suitable proton drive beam was available at the Syncho-<br />

Cyclotron. The quick spread of the technique from <strong>CERN</strong> to<br />

many other laboratories has resulted in a large user<br />

community, which has assured the continued development<br />

of the method, physics in the front-line of fundamental<br />

research <strong>and</strong> the application of the method to many applied<br />

sciences. The technique is today established as one of the<br />

main techniques for on-line isotope production of high<br />

intensity <strong>and</strong> high quality beams. The thick targets used<br />

allows the production of unmatched high intensity<br />

radioactive beams. The fact that the ions are produced at rest<br />

makes it ideally suitable for low energy experiments <strong>and</strong> for<br />

post acceleration using well established accelerator<br />

techniques. The many different versions of the technique<br />

will be discussed <strong>and</strong> the many facilities spread all over the<br />

world will be reviewed. The major developments at the<br />

existing facilities <strong>and</strong> the challenges encountered will be<br />

presented. Finally, the possibility of using the resulting high<br />

intensity beams for the production of intense neutrino beams<br />

will be briefly discussed.<br />

92-1058 - Design of a Muon Source for the Muon<br />

Ionisation Cooling Experiment<br />

Kevin Tilley (CCLRC/RAL/ISIS, Chilton, Didcot, Oxon)<br />

The MICE collaboration proposes to install a Muon<br />

Ionisation Cooling Experiment at the ISIS facility, at<br />

Rutherford Appleton Laboratory. This experiment will be<br />

the first demonstration of ionisation cooling as a means to<br />

reduce the large transverse emittance of the muon beam,<br />

produced during the early stages of a neutrino factory. In<br />

order to permit a realistic demonstration of cooling, a source<br />

of muons must be produced, possessing particular qualities,<br />

notably in emittance <strong>and</strong> momenta. This paper describes the<br />

present design for the muon beamline source, <strong>and</strong> the plans<br />

for its implementation at RAL.<br />
