## 8 Feb 2006 g-2 ALD Review

**Purpose**
- To make sure that we are prepared to face the “Particle Physics Project Prioritization Panel” (P5)
-     27-28 March 2006
- This review is considered a "scoping discussion," to be followed by a second ALD review if necessary
**Reviewers **(all local)
- David Lissauer
- Laurie Littenberg
- Jim Mills
- Brett Parker

## Charge

- Can the proposed experiment meet the physics goals?
- Is the cost estimate for the proposed experimental modifications realistic and defensible?  Does it require further work?
- Is the cost estimate for the proposed AGS modifications realistic and defensible? Does it require further work?
- Is the cost estimate for the proposed AGS operation realistic and defensible?  Does it require further work?
- Are there any other issues that have not been addressed?
- Would another ALD review prior to the P5 presentation be helpful?

**AGS Fixed Target Operations in RHIC Era –**
**The commissioning run: Sept - Nov  2001**

## AGS performance

- T. Roser

- Slow extracted beam (Rare Kaon decays)
- Fast extracted beam (g-2)
- Note: Lower total accelerated protons in later years           due to much shorter running time
