EDR Definition

EDR definition proposed at Beijing HLRF meeting :

• EDR to be completed in two more years, i.e. end of FY09.

• Will include detailed technical and cost plans that are considerably more mature than RDR.

• Will include a schedule and funding profile consistent with the plans.

• Will be sufficiently mature to provide a basis for international funding requests, implying – technology down-selects close if not already in hand– industrialization, industrial cost estimates close if not already in

hand. • Basis of EDR effort will be regional, inter-regional Work

Packages

Implicit EDR Goals

• Develop management structure for regional, inter-regional WP’s

• Develop EDR teams for each Area, Technical System

• Design R&D WP’s to mitigate high risk elements– Technical, cost, schedule risk

• Explore industrialization over EDR R&D period• Improve reliability of cost, schedule estimates• Document EDR to capture “Project Ready”

status by end FY09

What Types of Work Packages?

• Regional, e.g. Americas– Developed to support regional RDR, R&D programs– Leadership generally a major lab– Collaborators from other labs, regions

• Inter-regional– Larger programs, group involvement & funding from more

than one region– Funding by MOU agreement between partners

• University– Small individual or group efforts – Require R&D element of interest to university goals

• Industrial– Use industry to build first articles to ILC specifications– Develop industry cost, schedule experience– Develop inter-regional sources for high cost items

EDR WP Goals Summary

1. Develop overall global R&D goals for each Technical, Area System

2. Define WP’s for each Technical, Area System that include collaborators from multiple regions, institutions

3. Describe WP details to achieve EDR goals by end of FY09

1. Overall Goals for EDR R&D, industrialization2. WP Development for Tech Systems, Area Systems,

regional, inter-regional organization & management3. Personnel, M&S resources4. Schedules & Milestones5. Project Tracking

4. Sum together into integrated EDR plan

Expanding WP Scope and Effort into All Regions

• Two basic methods:– 1. Add to existing WP’s extra-regional collaborators

with home region financial support– 2. Create new WPs led by principals from a new

region, possibly open to collaborators from other regions as well

• General Principles: – Work Package assigned to a co-located group

easier to manage & control– Management teams needed to direct related inter-

regional programs

HLRF WP’s – Americas

• HLRF Technical Systems consists of Main Linac, Injectors, Damping Ring RF components:– Modulators and charging supplies, Klystrons,

Waveguide distribution, Interlocks & Controls

• LLRF included in Global Systems also must be integrated into RF systems

• Three Alternate Conceptual Design R&D projects underway:– Marx Modulator, Sheet Beam Klystron, Integrated

circulator-less Waveguide Distribution

WP Development Plans• Modulator & Charger Systems

– Production will be build to print or to specification. – Baseline and Alternate designs in development. – Develop detailed WP’s for subassemblies, new circuit, switch

device improvements, packaging design for tunnel, cooling design.

– Work toward multi-Region prototype construction and evaluation, industrialization, industrial prototypes

– Final down-select by EDR time.

• Conventional Klystron Systems – Assume klystrons purchased to specification. – Considerable work remains to develop industrial models, cost

models for high-volume production– Opportunities for modernizing HA versions of auxiliary solenoid

& heater power supplies, diagnostic interlocks, protection and controls, interface to HA Control System.

041807 HLRF DRAFT Global Design Effort 9

• Sheet beam klystron w/ PM focusing– First prototype still in development, due ~ 1 yr– Industrialization model, cost model for volume

production need much more work after first prototype

• Industrialization, collaboration opportunities: – Industrialization process– Prototype production & testing– Auxiliary systems – power, protection, interlocks– Sustained power test of cryo-modules in full power

10MW klystron substitution

041807 HLRF DRAFT Global Design Effort 10

• Waveguide Distribution System– R&D on Alternate designs– Machining, assembly techniques to minimize flanges– Tuning systems– Multi-Regional experimentation with fabrication techniques

(build to specification)– Industrialization of process– Design-for-cost and DFM

• RF Drive amplifier system– HA System design of RF drive systems interfaced with LLRF – Procure industrial prototypes– Develop improved diagnostics & protection

• HA Controls tools for RF test systems will be useful in other WP’s if produced in a timely fashion.
