To be used to prepare for Baseline Workshops – as needed

CFS/GBL 04 Aug, 2010 Marc Ross, Fermilab

Preparation for the 1st BAW

• July 23: AD&I meeting• July 28: SCRF meeting and draft BAW report

to be distributed– delayed

• Aug. 25: SCRF meeting and the final report (prior to the 1st BAW) to be distributed

• August 28: AD&I meeting

CFS/GBL 04 Aug, 2010 Marc Ross, Fermilab 7

Baseline Assessment Workshop

CFS/GBL 04 Aug, 2010 Marc Ross, Fermilab 8

• At the close of each BAW, we would like to write down a summary that is based on our common understanding of the issues.

• Developed prior to (and at ) the meeting itself

• A set of questions to be answered– Also serves as a draft outline for the summary

document

• The summary is the ‘Workshop Report’ – – to be submitted as part of ‘Top Level Change

Control’

Workshop Report

• The ‘Baseline Assessment’ is an advocacy process – A problem solving and integration process– We intend to develop a positive recommendation– For BAW 1, this means:

• Answering in the positive sense review panel (and other) comments on single tunnel / HLRF and gradient

• Preparation – SLAC 03.08, KEK 25-27.08

2nd BAW proposal

(SLAC)• January 18 2011: Reduced RF, focusing on

parameters, running scenarios and development plans

• January 19: Reduced RF focusing on cost and performance projections and potential upgrade paths and summary/recommendation,

• January 20: Positron Source Location, focusing on running scenarios and technical issues

• January 21: Positron Source Location, focusing on cost and performance projections and summary/recommendation.

7/23/2010

AD & I 23.07 (M. Ross) 11

Discussion expected at SLAC - BAW

1. Reduced RF• Global Parameters• Pulse length, n_b, power and cryogenic consumption• AS impact – sources, damping rings and BDS• Upgrade paths• R & D strategies• Cost impact – key cost items• Performance impact – luminosity performance and impact on physics

2. Positron Source Location• Running Scenarios – key aspects and luminosity as a function of energy• Technical parameters – operational issues as a function of energy• Variable repetition rate issues – power and cryogenic consumption;

sources and damping ring performance• Cost impact – key cost items• Performance impact – luminosity performance and impact on physics

TDP-2 R&D Plan

• Release 5 submitted to EC 04.08; – hope for ~ immediate release

• Updated R&D Plan for TDP2 reviewed by EC – Paris mid July

• Please read the CFS and S2 sections carefully

• R & D Plan appears to be ‘well-read’
