  1. Lessons Learned from CDMS@ Soudan Dan Bauer, Project Manager Fermilab, June 14, 2010

  2. Overview of CDMS

  3. CDMS II • First real project for the collaboration • FNAL joined to manage the project. • I moved from UCSB to FNAL in 2002 to take over as project manager from Roger Dixon. Before that, I was System Integration and Shielding Manager. • Proposed to DOE and NSF in 1998 and funded in 1999. • This was prior to the Critical Design process at DOE, and NSF was the lead agency at first. • Total project cost was $13M over 6 years, with another $5M from base funding. • Split roughly 50/50 between NSF and DOE • Documentation was mainly the proposal • Quarterly reports to agencies and annual reviews • There were no oversight groups (PMG, JOG), but we did have an external advisory board

  4. CDMS II Experience • Difficult to get university groups aligned with project goals • Strong tendency to continue R&D • Tendency towards scope creep • Resistance to reporting and documentation • Always treated as less important than technical progress • WBS was structured towards institutional needs, not deliverables • Agency issues • Not always clear whether NSF or DOE was calling the shots • Neither agency provided sufficient operations funding; FNAL base budget ended up carrying that load. • Technical difficulties • Very challenging to mount such an experiment in a remote underground site • Detector problems forced a down-scope from 7 to 5 detector towers Nevertheless, the experiment did succeed in reaching science goals within budget, albeit somewhat behind schedule.

  5. Post-CDMS II • Tortured history with the agencies • Proposed 25 kg experiment at SNOLAB in fall 2004 • No action taken by either NSF or DOE on that proposal during 2005 • To preserve our detector teams, with CDMS II project funds running out, proposed $2M Detector Development R&D project in 2006 • Followed with SuperCDMS Soudan project (TPC $2.5M) in 2007, to allow continued physics with CDMS II apparatus at Soudan

  6. SuperCDMS Soudan Project • Deploy ~15 kg of new 1” thick Ge detectors in 5 towers at the existing Soudan facility • Two new detector technologies available from R&D (mZIP similar to CDMS II, and double-sided iZIP) • Authorized from August 2009 review to proceed with 4 towers of mZIP and 1 tower of iZIP • Requested March 2010 review to propose 5 towers of iZIP

  7. Recommendations from the March 8 review • Before building more than 1 iZIP tower: • Provide results of mZIP tower at Soudan and a surface test of current production of iZip detectors. • Provide TDR for experiment with iZIP detectors. • Provide clear scope, budget & schedule and updated PEP for the proposed funding provided in the $2.5M MIE, including costing for what has already been built. • This should be done by mid-May. A phone conference with the panel should be held before going forward

  8. Progress towards these goals • mZIP analysis from Soudan run • Nearly complete and will have report by end of June • iZIP TDR • Report expected by end of June • iZIP Fabrication and Testing • First production iZIPs made and tested • Some problems with these devices • Transition temps too low, TES resistances too high • 2nd round of production completed and 3rd round beginning • Believe we have fixed the problems • Cryogenic tests next week to confirm • Phone review is now scheduled for July 12, 2pm Central

  9. Project Schedule

  10. Project Budget

  11. Requires continued effort from FNAL • Scientists • Bauer, Yoo, Hall, Hsu • Technical support to maintain Soudan • 0.25 FTE Eng (Schmitt), 0.25 FTE Tech (Ruschman, W. Johnson) • Soudan operations • Support mine crew through FY2013 (minimum level = 5 FTEs) Important to continued science and technical progress, but this is a major distraction for the FNAL group from SuperCDMS SNOLAB project

  12. Summary of lessons learned • Need to start with well-defined project scope and plan defined by PEP and PMP • Develop a WBS that is focused on deliverables, not institutional priorities • Need to use modern project scheduling and tracking tools • Need professional project help!
