VTS2&3 Project Status
Ruben Carcagno, Camille Ginsburg, and Cosmore Sylvester
On behalf of the VTS Group
August 31, 2009
31.Aug, 2009 SRF Mtg 2
Cavities to accommodate ILC/SRF R&D
9-cell and 1-cell elliptical ILC cavities HINS/Project X
SSR1SSR2 TSR9-cell elliptical cavities
Conclusion VTS1 is sufficient to support FY09, FY10 test plans VTS2 with larger diameter operational by ~Dec. 2010 to
support increased throughput and SSR2, TSR as needed VTS3 needed by ~Sep. 2011
Our Plan: New design with Indian Institutions for VTS2&3 Build VTS2 in U.S. Industry Build VTS3 slightly later in Indian Industry with same design
VCTF Upgrade Cavity Requirements
Do not fit in VTS1
Total ~200 VT/year

VTS2&3 Cavity Requirements
Provisions for testing the following types of cavities are required:1. bare 1-cell 1.3 GHz elliptical cavities2. bare 9-cell 1.3 GHz elliptical cavities3. dressed 9-cell 1.3 GHz elliptical cavities, with helium gas return pipe absent 4. bare 325 MHz single-spoke resonator SSR1 5. bare 325 MHz single-spoke resonator SSR2 (preliminary design)6. bare 325 MHz triple-spoke resonator TSR (preliminary design)

Projected cavity throughput
• Projected Americas total R&D cavity process/tests 2009-2012 for Project X and the ILC.
• Projected Americas annual production process/test for Project X 2013-2015.
• Note: SSR2 and TSR designs and requirements are preliminary.

VCTF Upgrade
Increase cavity test throughput Current throughput estimate: 48 cavity tests/year Increase throughput to >200 cavity tests/year by Oct 2011
Planned upgrades Improve cryogenic system reliability Reduce interference with magnet test program Two more cryostats and staging area
existing cryostat & radiation shield Very similar to
Feb.2007 plan

VCTF cavity test throughput per month for Oct.2007-Apr.2009. Throughput goal of 48 cavity tests per year has been achieved short-term under ideal conditions.
Projected number of cavity tests per quarter, assuming the completion of the planned cryogenic system upgrades and the addition of two cryostats on the timescale shown.

VTS/IB1 FY09 Plans
• Plan to obligate funds in FY09 for VTS Upgrades (VTS2&3 plus cryogenic infrastructure upgrade) using ARRA + SRF funding
• Prepare space for new cryogenic equipment – ready FY09
• Procure two purifiers, cryogenic piping & instrum, 1,500 KVA Transformer - FY09
• IB1 civil construction for upgrades: two larger diameter pits plus trenches, dedicated 10-ton crane bridge
– Place POs before end of FY09, civil construction summer FY09
– Very disruptive to cavity and magnet test programs (~ 6 weeks IB1 downtime)
– Fermilab internal (FESS/TD Support) activity for civil construction started
• Complete design of full VTS cavity staging area – FY09
• Design VTS2&3 cryostats as part of FNAL-Indian Inst. collaboration
– As similar as possible to VTS1 to minimize design effort/time: major changes include larger diameter & length, higher capacity J-T heat exchanger
– Includes top plates, magnetic & radiation shields, cryostat internal cryogenic piping and instrumentation
Preliminary Design Review in May 2009
• Procure VTS2 – FY09 – end of CY09
Shown at May DOE/SRF Review

Since the May DOE/SRF Review
• VTS2&3 Cryostat– Preliminary Design Review May 22, 2009
• Thanks to committee: Jay Theilacker, Phil Pfund, Tom Nicol and Arkadiy Klebaner (ex officio, MTF cryo safety chair)
• Committee report delivered May 29, 2009 revealed that the level/detail of documentation used for VTS-1 would be significantly insufficient for VTS 2&3
– We came up with a plan for improved documentation June 17, 2009, based on guidelines being adopted in TD, as well as responses to the committee’s detailed questions
– We received a final memo from the committee Aug.28, 2009, accepting our documentation plan, and largely accepting our responses

Documentation Plan
1. Functional Requirements Specification (FRS):– will define the programmatic needs for VTS 2&3, clearly specify what type and what configuration of SRF cavities will be
tested in these cryostats, and specify what are the test parameters (e.g., temperature range, maximum power dissipation, etc.). This specification will motivate the VTS2&3 cryostat subproject and other subprojects for the VTS2&3 project; whereas the remaining documents in this list are specific to the VTS2&3 cryostats.
2. Statement of Work (SOW): – will define the work scope, objective (using the FRS as a reference), institutional responsibilities, and top level organization
of the VTS2&3 cryostat work. It will clearly state the responsibilities of Fermilab and Indian Institutions in more detail than the existing MOU addendum.
3. Project Management Plan (PMP): – will define how the SOW will be executed. The PMP will include the project approach, project organization with team
members and their affiliations, a list of major project documents, the document control system, a list of project reviews with level of formality, the Work Breakdown Structure (WBS), the top-level project schedule with milestones, a cost estimate, and a risk assessment.
4. Technical Requirements Specification (TRS): – will specify the requirements for the VTS 2&3 cryostat design to satisfy the FRS. This document is not a procurement
specification, and it does not include fabrication details or vendor responsibilities. This document provides the necessary design input information, independent of which institution or organization is responsible for developing the design.
5. Technical Design Report (TDR): – will describe the VTS 2&3 cryostat design based on the TRS. This document will include design details such as
calculations and drawings, and may reference design notes.
6. Procurement Plan (PP): – will define the procurement strategy for the VTS 2&3 cryostats. This document will define procurement packages, type of
procurement (e.g., built to print, built to performance), procurement steps (e.g., RFI, RFP), vendor selection criteria, fabrication reviews, etc.
7. Procurement Specification (PS) for VTS-2 from a US vendor: – based on a reviewed and approved TDR, and vendor feedback from the RFI, procurement specifications for U.S. vendors
for the VTS-2 cryostat will be written. These specifications will include fabrication details and vendor responsibilities and a complete set of design drawings from the TDR. A separate procurement specification will be written by RRCAT colleagues, and approved by Fermilab, for procurement of VTS-3 in India.

Latest Updates
• Functional Requirements Specification– First draft released today; awaiting comments– A document addressing need for J-T heat exchanger
containing calculations and measurements was released last week; internal review in progress
• VTS2&3 Civil Construction– Selected (new) vendor eventually declined to do the
work– New RFP with one vendor (same as for VTS-1)
submitting bid– Pre-construction meeting with that vendor tomorrow– Expect IB1 operations/cryo system shutdown to start
this week– Shutdown of IB1 operations ~6 weeks duration
• Few if any vertical cavity tests possible before mid-November
