TDR Plans and Scope

GDE Stated Prime Deliverables

1. An updated technical description of the ILC in sufficient detail to justify the associated VALUE estimate

2. Results from critical R&D programmes and test facilities, which either demonstrate or support the choice of key parameters in the machine design

3. One or more models for a Project Implementation Plan, including scenarios for globally distributed mass-production of high-technology components as “in-kind” contributions

4. An updated and robust VALUE estimate and construction schedule consistent with the scope of the machine and the proposed Project Implementation Plan

Part I: Tech. Design Phase R&D

• Comprehensive report on TDP R&D programmes– where and how we spent the money

• Similar in scope to R&D sections in interim report– more technically detailed– more conclusive

• Report R&D results should support baseline (decisions) in Part II– But scope can be broader, i.e. R&D on alternative

concepts


Part I: R&D - Outline

1. Introduction 5 pages

2. Superconducting RF Technology 75 pages

3. Beam Test Facilities 75 pages

4. Accelerator Systems R&D 50 pages

5. Post-TDR R&D 20 pages

6. Conclusions 10 pages

Detailed section outline available here


RDR vs TDR Part II

• RDR was divided into – Accelerator Systems (sources, DR, BDS etc.)

– Technical Groups (cryomodule, RF, magnets vacuum etc.)

• TDR Part II is Accelerator System orientated– Each sub-system will cover its own technical

systems– Better suited to TD Phase project structure– Acknowledge lack of RDR-like tech. groups


Part II Example Chapter

6 Damping Rings6.1 Top-level DR layout and parameters6.2 Lattice description6.3 Beam dynamics (e-cloud, FII and classical

instabilities, LET)6.4 Vacuum system design (including e-cloud

mitigation, impedance etc)6.6 Magnets and power supplies6.7 Instrumentation and feedback systems

Description of regional baseline variants


Nicholas Walker

Need to discuss this with Akira, as it is different from his outline.

Special Cases: CFS

9 CFS9.1 Introduction 9.2 Asian Region Siting Studies9.3 European Region Siting Studies9.4 Asian Region Civil Design9.5 Americas Region Civil Design9.6 European Region Civil Design9.7 Mechanical Design9.8 Electrical Design

15.11.2011

No Americas siting study

Civil construction design now reflects regional design differences

Common mechanical and electrical design concepts



10. TeV Energy and Luminosity 20 pages Upgrade

– integration of planned white paper

11. Cost and Schedule 20 pages

12. Project Implementation Planning >20 pages– integration of stand-alone report (57 pages)– see presentation by E. Paterson

13. Post-TDR Engineering 20 pages– including technical risk assessment

• ILC-EDMS group populating EDMS WBS– as part of on-going baseline review

process

• Mandatory documents required– parameters– system description / interfaces– treaty points– etc.

Coordination with Physics & Detectors

• Time scale and scope– important to publish all documents as a set– as for RDR

• Look and feel– Same templates and layout themes should be

used

• Technical consistency– Obvious– Especially important for MDI

• Possible joint documents– Joint Executive Summary– Outreach document

• Primary coordination via respective TEBs– just starting

Consolidated Accelerator Systems and CFS/Global meetings (now focused on TDR work)

To be used for TDR TEB and Cost Management Team meetings


2011 Preparation Work• TEB kick-off meeting

– editing assignments and agreed-upon workflow• Finalise detailed outline

– headings– estimated page count– section scope– authors

• Request feedback from authors– especially for schedule– Note: many authors have more than one writing assignment

• Consolidate/adjust writing schedule• Technical preparation

– Common workspace– LaTeX template(s)– …


Summary

• Preparation for TDR well underway– Now primary GDE focus (together with costing/industrialisation)

• 2+1 separate volumes– Executive Summary– Part I R&D– Part II Baseline Design & Cost

• Accompanying outreach document– broader non-scientific readership

• Preparation work remainder of this year, writing starts next year– of course earlier is better

• Coordination with Physics & Detector groups just starting• Very aggressive scope and schedule

– However we are building on the RDR and the Interim report
