NASA Scientific and Technical Aerospace Reports

With the increasing complexity of today’s systems, detailed performance analysis is more important than ever. We have
developed DynTG, a tool for interactive, dynamic instrumentation. It uses performance module plugins to reconfigure the data
acquisition and provides a source browser that allows users to insert any probe functionality provided by the modules
dynamically into the target application. Any instrumentation can be added both before and during the application’s execution
and the acquired data is presented in realtime within the source viewer. This enables users to monitor their applications’
progress and interactively control and adapt the instrumentation based on their observations.

The response of a new Canberra Alpha Analyst (Chamber No.’s 101 - 124) used by the Hazards Control, Radiation Safety
Section, WBC/Spectroscopy Team has been studied with respect to an existing Canberra system. The existing Canberra system
consists of thirty six Model 7401 alpha spectrometry chambers (Chamber No.’s 1-36) and has been DOELAP qualified for
the routine Alpha Spectroscopy program used in LLNL’s in vitro bioassay program. The new Alpha Analyst system is an
automated system that is controlled by the same software and computer system as that used for the existing Canberra system.
This document compares results from the existing Alpha System with the newer Alpha Analyst system.

Heavy ion and radiation transport calculations are in progress for conceptual beam dump designs for the fragmentation
line of the proposed Rare Isotope Accelerator (RIA). Using the computer code PHITS, a preliminary design of a motor-driven
rotating wheel beam dump and adjacent downstream multipole has been modeled. Selected results of these calculations are
given, including neutron and proton flux in the wheel, absorbed dose and displacements per atom in the hub materials, and
heating from prompt radiation and from decay heat in the multipole.
