The Charge-Changing Fragmentation of 10.6 GeV/nucleon ^(197)Au Nuclei

Autor: Geer, L. Y., Klarmann, J., Nilsen, B. S., Waddington, C. J., Binns, W. R., Cummings, J. R., Garrard, T. L.

We have measured the charge-changing cross sections of 10.6 GeV/nucleon ^(197)Au nuclei interacting in targets of CH_2 (polyethylene), C, Al, Cu, Sn, and Pb. Cross sections for H are calculated from those measured in C and CH_2. The total charge-chan

Nuclear Interaction Cross Sections for UltraHeavy Nuclei

Autor: Garrard, T. L., Cummings, J. R., Geer, L. Y., Klarmann, J., Nilsen, B. S., Waddington, C. J.

We summarize additions to our data base of charge-changing cross sections for relativistic ultraheavy nuclei interacting in targets ranging from H to Pb. We have improved parametric fits to those cross sections as functions of energy and of projectil

Detection Efficiency of the CRIS Scintillating Optical Fiber Hodoscope

Autor: Binns, W. R., Crary, D. J., Cummings, A. C., Geer, L. Y., Klarmann, J., Lawrence, David J., Mewaldt, R. A.

Measurements of the detection efficiency of a Scintillating Optical Fiber Trajectory (SOFT) detector for 660 MeV/n Carbon, Boron, Beryllium and Lithium nuclei and for 300 MeV/n Fe nuclei are described. Detection efficiencies of 99.8%, 98.7%, 97.5%, a

Energy Dependence of the Fragmentation of UH-Nuclei

Autor: Geer, L. Y., Klarmann, J., Nilsen, B. S., Waddington, C. J., Binns, W. R., Cummings, J. R., Garrard, T. L.

The fragmentation of 10.6 GeV/n Au in CH_2. C, Al, Cu, Sn, and Pb targets has been studied using an array of ion chambers, multi-wire proportional counters (MWPC), and Cherenkov counters. Total charge-changing cross sections were found to be monotoni

UHCR: A Cosmic Ray Mission to Study Nuclei in the Charge Range From 20 ≤Z ≤100

Autor: Binns, W. R., Garrard, T. L., Geer, L. Y., Klarmann, J., Mewaldt, R. A., Waddington, C. J.

A definitive study of the elemental abundances of nuclei over the charge range of 20 ≤ Z ≤ 100 requires a satellite mission capable of obtaining high statistics and excellent charge resolution over the full charge range. Such a mission, utilizing
