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 />
