## Changes to BCD just before Beijing

** ****Change Configuration Records**
**Params & ML (Superseding CCR#20) **
**Requested by Raubenheimer**
**CCB Reviewer (Funk, Pagani, Mishra) **
**Partial Approval Recommended (Jan 23, 2007)**
**CCR#24d: To modify the baseline parameters such that the number of bunches per pulse is reduced from 2820 to 2670 and beta_x* decreased from 21mm to 20mm.  This allows us to achieve still the same peak luminosity of 2E34 while reducing the beam current from 9.5mA to 9mA.  ****(Recommended Approval)**

## CCB just before Beijing

**CCR#24a: Change of the cryomodule (CM) layout driven by each of the 10MW klystron RF unit, as ****(8-8-8) --> (9-8-9).**** Thus, 26 cavities are to be driven by one 10MW klystron, rather than the previous 24. ****(Recommended Approval)**
**CCR#24b: Elimination of RF unit overhead. Previously, 3.5%. Now, 0%. Thus, maximum beam energy 250GeV is available only if all RF units are in operation.  ****The conventional facilities, including the tunnels, are to be maintained to accommodate the missing 3.5% worth of RF systems if/when determined needed.**** ****(Recommended Approval)**
**CCR#24c: Elimination of the uncertainty factor in the cryogenic static heat load. Previously, 50%. Now, 0%. This allows lowering the cryogenic capacity by 13%. ****(Recommended Rejection)**

## S2 Task Force Report: RF Unit Test

**The minimum size system test needed to confirm the performance of a new design is a single RF unit with ILC like beam.****  **
**As many tests are statistical in nature, a longer string test with several RF units or multiple tests with one RF unit would be better.**
**As construction of the project starts, a test facility (or facilities) will be needed to qualify manufactured RF unit components of the final consolidated ILC linac system design.  **
**These components may be built at industries in different regions.  **
**One of the possible scenarios is to build a test string with contributions of a total of several RF units from the three regional teams.  **
**There are many factors that will influence the choice of the size of the string and whether the goals can be accomplished instead through several smaller tests or one long string.****  **
**These factors will be coupled to the future industrialization strategy adopted for ILC main linac components.  **
**Therefore we cannot at this stage determine the ideal scale of this second phase of system tests. **

## A Climb towards EDR

**GDE will reorganize its efforts on two fronts**
**Coordination and Prioritization of Global R&D**
**Develop coordinated R&D Plan**
**R&D on the critical elements of the machine as defined in the RDR **
**To ensure high performance and a cost effective machine.**
**To give the optimum return on the investment  of the contracting governments.**
**Preparation for engineering design**
**Need more of a project management structure**
**Engineering design will be of the machine that we believe can build and which specifies the project in sufficient detail by 2010 to allow “approval to construct”* by participating governments.**

## The American Regional Team is ahead in Planning for ILC R&D and ERD Management

The scope covers what is needed to complete the Technical Design Report (TDR), 
Produce an engineering design for the ILC, 
Complete the R&D needed 
to demonstrate feasibility of the key baseline technologies, 
to finalize baseline design choices and ensure reliability of the machine
before starting production of baseline systems and components
to continue development of alternatives for cost reduction or performance enhancement. 

This work scope should be completed by the end of FY09.

**The scope covers what is needed to complete the Technical Design Report (TDR), **
**Produce an engineering design for the ILC, **
**Complete the R&D needed**** **
**to demonstrate feasibility of the key baseline technologies, **
**to finalize baseline design choices and ensure reliability of the machine**
**before starting production of baseline systems and components**
**to continue development of alternatives for cost reduction or performance enhancement.**** **
**This work scope should be completed by the end of FY09.**

**ART planning: Scope**

## ART Planning: Siting

**The final TDR will need to be site-specific, but at this time the site is not known. For all WBS categories, activities should be separated into **
**those *****common***** items that would be done in the Americas no matter where the machine was sited (e.g, all R&D, and site-independent accelerator and component design), **
**those *****site-specific***** design items that can only be done once a site is selected.  **
**Site-specific design activities will need to be deferred until after the site is chosen, which, for the purposes of developing this plan, will be assumed to be later than FY09. **
**Thus, site-specific TDR design will not be included in the plan. This implies that additional TDR design work will need to be done after the site selection, i.e., in 2010 or later, before the project can be started.**

- ILC R&D Meeting at Fermilab

- 2/21/07

## ART: Regional Interest

**There are classes of preparatory site-specific activities for an Americas site that are needed prior to a siting decision. **
**These include primarily civil engineering activities, and but may also include Americas-site-specific accelerator design. **
**They may also include industrialization activities and the development of vendors, especially in the SRF area.****  **

## ART: Co-ordination with GDE

**The plan for the ILC-Americas program is being well-coordinated with the GDE priorities and with activities in the other regions. **
**GDE planning for certain R&D activities have matured (Main Linac R&D).**
**Some are still developing (S3-S7 Task Forces)**
**  **
**For the ERD/TDR engineering and design effort, the detailed GDE plans are not yet well developed, ART plans will adapt as GDE planning matures**

## View on EDR

**The ART has established a WBS management system to manage the ILC R&D and EDR work under the ILC Regional Director.**
**The work packages under this structure has already been developed.**
**It is being refined due to new budget guidance.**
**It is hoped that other regions will adopt similar structure.**

## Engineering Design Report

**What is the EDR?**
**The definition of EDR is still developing with in GDE-EC and ILC communities.**
**The general goal is to bring ILC to the point of “Construction Ready”.**
**Can make a construction proposal**
**Minimum Requirement**
**Done “much of” the engineering and R&D**
**How do we organize Work?**
**GDE proposes to organize the work to toward the EDR by Project Management and through formal Work Package**
**A Work Package = a commitment for accomplishing task defined in the GDE WBS**
**Reporting will be to the GDE Project Management Office**
**Work will be organized through MOU**

- ILC R&D Meeting at Fermilab

- 2/21/07

## Forbidden GDE

**Planning underway **_**internally**_** in GDE (EC)**
**Develop an “Engineering Design Report” over the next 2-3 years.**
**Develop a “work package” structure, where collaborating institutions will take responsibility for these, coordinated through the GDE **
**Design will evolve through value engineering and R&D program**
**General Goal is to have Construction Proposal ready by 2010**

- ILC R&D Meeting at Fermilab

- 2/21/07

## GDE evolution

**Many aspects of GDE management work well. Delivery of the EDR therefore ****evolution not revolution****.**
**However, EDR will need different GDE skill set **
**Much more engineering design => reform of GDE personnel **
**During the EDR GDE should concentrate on central functions, project management, coordination etc. **
**Many people outside current GDE – ****(there are only ~35 FTEs in current GDE)**** **
**are doing vital work in this area; **
**some inside the GDE have changed emphasis and level of activity. **
**Need rationalization of GDE membership. **
**GDE will expand to contain all persons working on the ILC.**
**There are discussions of a New Management Structure for GDR. This is being developed. **

**Notes:**
get rid of GDO - get rid of home base

## The EDR: Coordinated Work Package

**To produce the factor two in FTE growth and to improve efficiency and reduce duplication of effort, **
**Propose to organize EDR phase by dividing the tasks into work packages which can be ****bid for**** by consortia, **
**This would be encouraged by individual labs, universities etc.**
**This reduces the problems of coordination and avoids duplication in R&D. **
**It also greatly eases the problem of increasing FTEs since people available for only small fractions of their time but with vital expertise can be efficiently utilized within consortia **
**Consortia will be obliged to deliver, even at the expense of allocating more FTEs than they might originally have intended.***** ***

## Effort Estimate: Size for EDR

**Estimate from individual area systems - timelines from S task forces are roughly compatible with 2010 milestone without enormous increases in effort from current**
**from some of the S task forces ~ factor 2 growth required to do necessary work. **
**Rule of thumb, ~10% of total effort on project required for pre-construction phase => 300 - 400 FTE years. **
**Roughly 250 FTE years currently working across all 3 regions on ILC. **
**Not all of those are working in areas relevant to EDR production.**
**Points to GDE growth to ~ 400 - 500 FTE years. **
**Seems unlikely that such an increase can proceed under the current paradigm of ad hoc assignment from major laboratories, relatively uncoordinated across broad range of R&D. **

**Notes:**

Present annual effort ILC+GDE is about 250 FTEs; probably need another 150 FTEs to produce the EDR.And evolution of skill set.

## Work Package Example:Fermilab ILC Cryomodule Design

-  The baseline ILC Cryomodule will have 9 & 8 9-Cell cavities per cryomodule. The quadrupole will be at the center in the Cryomodule with 8 Cavities.
-  Every 3rd cryomodule in the linac would include a quadrupole with a dipole corrector and BPM package.

## Cryomodule Design and Fabrication

**ILC Cryomodule working group (Fermilab, INFN, DESY, KEK and CERN) is working towards a design of an ILC cryomodule. This design is expected to evolve through EDR Phase.**
**The Goal is to design an improved ILC cryomodule with Value Engineering and industrial Production **
**Dipole, Quad and BPM package at the center**
**Tuner Design**
**New Cryogenic Distribution**
**Shorter cavity-to-cavity interconnect length (Improve packing factor)**
**Simplify assembly procedure**

## EDR: Fermilab Work Packages

**Fermilab is well positioned to contribute significantly to the EDR development with its engineering resources**
**Fermilab has several staff in the lead position in the Area and Technical Systems of ILC. **
**EDR will require significant engineering and accelerator physics resources. (Just a few thoughts)**
**Main Linac**
**Design**
**Cavity and Cryomodule**
**Cryogenics**
**Instrumentation**
**Magnet**
**Cryogenic and Conventional**
**BDS**
**Crab Cavity**
**CFS**
**It will require about ~30 Full time Fermilab scientists and Engineers (Assigned ~100%). **
** ****Supported with 30-50 FTE part time staff**
