1. IDT Meeting Welcome Brent Fultz California Institute of Technology Broad-brush overview of Hardware, Software, Management

2. ARCS Instrument Concept Image from Robb Williams March, 2002

4. Project Issues Written response by Dec. 1 to DOE Baseline Review of March 2002. Management Big Issue: Develop a Project Execution Plan Other Issue: Role of IDT Issues under Control: MOA, Reporting Requirements Technical Shielding, in-vacuum detectors Sample manipulation today — single crystal manipulation (later: sample changer) Other Issues: Choppers, optics, poisoning depth Software Plan today — web service

5. Big Hardware Issue #1: Instrument Shielding Progress: “Shared” and ARCS shielding calculations performed for RTBT wall, beamstop, “sample” Unpleasant Facts: Dosage to human in figure: 10 - 100 rem/hour Beamstop: 4 meters in length, 2 m dia. Ideas: Sample hutch? Beamstop restrictions on SEQUOIA? SEQUOIA Fermi chopper placement?

6. Big Hardware Issue #2: Detector Tubes in Vacuum Concept: 8 Detectors per Module Neutron Shielding Read out card (ROC) mounting Status: Preliminary tests good Vacuum system in place at ANL Problem: We need to do try some cycling outgassing, etc. No prototype electronics yet ! (delays critical decision on vacuum operation)

7. Development of Software Plan No plan yet -- expected Jan. 2003 User survey was quite successful -- Thanks. To make the plan, we have to: Select computing model Define the scope of the project Get experience in estimating effort

8. Project Execution Plan Not a project plan -- Doug will show the ARCS project plan. A Project Execution Plan gives principles for the Who, What, Why, When and How for how the project will get done. We need IDT input on some topics, especially: Role of IDT in project Change control procedures Milestones

9.
