May 2008 Subsystem Review

Introduction

The May 2008 Hall D Subsystem Review will cover all aspects of Hall D that have not been reviewed previously under the auspices of the 12 GeV project office. This includes electronics, trigger, DAQ, event and hardware monitoring, and experiment and hardware controls. The review will also cover detector integration and assembly, but this is being handled by the Hall D engineering group.

Charge for the Review Committee

No charge for the committee has been established yet (Mar 2008). A potential charge, based on charges from previous reviews, might be:

The scope of this review includes all aspects of the following Hall D systems and efforts: electronics, trigger, DAQ, event and hardware monitoring, experiment and detector controls, and detector integration and construction.

This may include: material selection, fabrication choices, construction schedule, safety considerations, levels of redundancy, commissioning procedures, costs for materials and labor, quality control, operational reliability and longevity, and any other considerations that may influence the construction and operation of the Hall D detector.

You are asked to address the following questions:

1. Are the technical performance requirements adequate, appropriate, and complete for each system?

2. Do the current designs and plans appear likely to achieve the performance specifications with a low risk of cost increases, schedule delays, and performance problems? Are there opportunities for improvements in cost or performance that the design teams should consider?

3. Are the R&D efforts appropriate, complete, and likely to reduce risks?

4. Have ES&H considerations been adequately incorporated into the designs and plans?

Preparation

Below I list topics the review committee might focus on. Clearly the committee cannot investigate all of these in depth, but we can expect they will want an overview of all of them, and may probe a few in depth.
