The workshop on polarized targets and materials-summary

Abstract

The Workshop presentations and discussions centered on recent developments in the following areas: I. irradiated ammonia. Interest in irradiated ammonia as a target material has been generated by the original report of proton polarization >90% and by subsequent observations of high radiation tolerance, coupled, of course, with a high content of hydrogen. II. Polarized atomic hydrogen. The possible applications of spin-polarized hydrogen to intense polarized sources are more promising than target applications. III. Polarized target technology. There is a general dearth of hard information on this important subject, in the sub-Kelvin range at moderate-to-high thermal fluxes. IV. Chemical doping. Preliminary trials on chemical doping have yielded proton polarizations in excess of 70% in materials with hydrogen fractions up to 19 wt%. 4 references, 1 table.
