Abstract

As part of a recent calibration at the LBL Bevalac for the Heavy Nuclei Experiment on HEAO-3, we have compared the response of a set of laboratory ionization chambers to beams of _(26)Fe, _(36)Kr, _(54)Xe, _(67)Ho, and _(79)Au nuclei at maximum energies ranging from 1666 MeV/amu for Fe to 1049 MeV /amu for Au. The response of these chambers shows a significant deviation from the expected energy dependence, but only a slight deviation from Z^2 scaling.

Additional Information:© 1985 NASA/STI. Provided by the NASA Astrophysics Data System. The success of this calibration was largely due to the efforts of the staff at LBL, especially Hank Crawford, Mel Flores, Peter Lindstrom, and Fred Lothrop. John Epstein provided invaluable assistance in constructing and aligning the instrument.
