A High-Resolution Direct-Geometry Chopper Spectrometer at the SNS |
Baseline Review and Software Workshop (March, 2002)
March 14, 2002 was the Baseline Review of the ARCS project
at the California Institute of Technology, Pasadena, CA, USA.
March 15 and 16 were a Software Workshop, emphasizing data standardization and
the development of robust and maintainable software for the analysis of data from
inelastic neutron scattering.
This website contains the information provided to the reviewers before March 14.
Also included are the Powerpoint presentations for the 1-day Review and the subsequent 2-day Software Workshop.
Here is the agenda, the
cover letter, the
charge to the committee, and the
list of reviewers.
Material Presented at the Review and Workshop. These Powerpoint presentations are in the order presented. The first group were presented on Thursday in the Review, the second group were presented in the Software Workshop: Overview

Software Plan for
ARCS Brent Fultz (Caltech)
Saturday was a full day of demonstrations of software packages. Some were live, others canned, but all were effective in showing the look, feel, and scope of the packages. There was extensive discussion on maintenance of software, the NeXus standard, and the capabilities of Python for integrating the software packages into a coherent structure for inelastic neutron scattering.

Here is a general interest news report about ARCS, which appeared in the Jan. 2002 issue of Engineering and Science, an official publication of the California Institute of Technology. It was written by Doug Smith of Caltech, who has a unique sense of humor. Nevertheless, there is no such thing as bad publicity.

Here is the ARCS proposal as submitted to the Department of Energy on June 3, 2001.
