## Draft Report of the RHIC Planning Group

**T. Ludlam**
**Open Meeting on RHIC Planning**
**Dec. 3-4, 2003**

## RHIC Planning Group:  Goal/Charge

**Map the broad scientific priorities of the RHIC community onto a realistic schedule for facility operations and upgrades.**

**Starting points...**
-  Beam Use Requests and Decadal Plans
-  PAC and Detector Adv. Comm. Recommendations
-  Requirements for machine operation and evolution
-  DOE Budget Guidance
-  NSAC Long Range Planning process

**5 Year Plan**
**20 Year Outlook**

** ****Optimize ops scenarios**
** ****Establish the scope and spec.s for RHIC II**
** ****Update plans for eRHIC**

**Input to BNL plan for DOE Review, 12/31/03**
