DOE/NSF ILC Detector R&D Review

1. + DOE/NSF ILC Detector R&D Review June19-20, 2007 At Argonne National Laboratory Paul Grannis Jim Whitmore

2. ILC Detector R&D review: • The responsible organization is the American Linear Collider Physics Group, the Americas portion of World Wide Study. • There were separate reviews of Americas Regional Team of the GDE on the accelerator R&D side in 2006 and 2007. • This is first ILC Detector R&D review by NSF and DOE. • The ILC physics and detector community through ALCPG has been conducting a broadly based R&D program to develop appropriate options for ILC detectors

3. History of Detector R&D: • University detector program started in 2003, with submissions to both NSF (UCLC) and DOE (LCRD). • DOE NSF • FY03 $412K $77K • FY04 $700K $0K • FY05 $700K $117K • FY06 $1048K $300K • FY07 $1800K $385K • NSF and DOE merged the program into one jointly reviewed effort, through an Umbrella Grant to U. Oregon in 2005 • These funds have supported many universities (and small labs – ANL, LBNL, BNL) at quite low levels. In FY06, 33 grants at average level $35K each. • This year’s awards will be the last in the current 3-year umbrella grant.

4. In mid 2006, visit of ALCPG to stress need for some improvement in detector funding. • DOE/NSF asked for a plan for detector R&D funding, with goals, priorities, milestones, and resource needs. • This review is the first presentation of such a plan. An outcome of that meeting came from the desire to put some funds to actual deliverables for test, rather than more generic studies and R&D. • When the continuing resolution finally turned into a FY2007 budget, some funds were released as ‘supplements’ for test activities. • DOE awarded $775K and NSF $75K for the supplements

5. Upper and lower guidance estimates for the DOE portion of detector funds over the next several years were given to ALCPG (in $M). The time profile adopted here corresponds to starting the ILC construction project in about 2013. Guidance is only advisory, subject to change • Year upper guidance lower guidance • Fy08 8 4 • Fy09 10 5 • Fy10 15 7.5 • Fy11 20 10 • Fy12 20 10 • Fy13 10 5 • Sum 83 41.5

6. Review Team: DOE: Paul Grannis, Jerry Blazey and Howard Nicholson NSF: Jim Whitmore Reviewers: Tim Bolton (Kansas St U) Dave Cassel (Cornell U) Meenakshi Narain (Brown U) Regina Rameika (Fermilab) Michael Rijssenbeek (Stony Brook) -- CAL @ Hamburg Bing Zhou (U. Michigan) -- Tracking @ Beijing Consultants: Bill Willis (Chair of the GDE Global R&D Panel by phone) Chris Damerell (Global coordinator of detector R&D)

7. Each talk you will hear: • Cover activities of all US groups active in the R&D on the topic (universities and Labs) • Scientific motivation for the goals of the R&D • Progress to date • Future plans, milestones and needs for support • Place the R&D in the international context

8. ILC Detector R&D review: Charge elements • Evaluate the organization and oversight of the detector R&D program • Review and comment on the past R&D accomplishments through the LCDRD programs and the activities at the laboratories. Is the scope of these activities appropriate? Address the coordination of university and laboratory R&D. • Assess the planned program for FY2007 and beyond – its goals, priorities, milestones and resource needs. Are the goals and the schedule advocated reasonable and achievable? • Evaluate the R&D in the US in the context of the global activities being coordinated by the WWS. • The emphasis will be on generic detector R&D, but also evaluate their plans for moving from generic R&D to development of experimental proposals.

9. Comments: • We do not seek advice at this time on specific detector concepts, but rather look for focus on the generic R&D on detector technologies. We are interested however in the committee’s view of the process outlined for evolving specific detector proposals. • Although the funding streams for detector R&D at the major labs and the universities/smaller labs have been separate in past, we seek committee comment on the integration of lab and university efforts, and advice on ways to strengthen the coordination.

10. We ask for reviewers to evaluate the ALCPG plans with this guidance in mind, and comment on the priorities and goals articulated. • We would like to understand the impact on the stated goals from increased or decreased funding. • Through individual reviewer’s participation in international reviews, and materials presented here, we would like your comments on the integration of the US effort with those worldwide. • [Chris Damerell, global coordinator of detector R&D, is attending this review as an observer, and is available for closed session consultation with the committee. Bill Willis, chair of the GDE R&D board could not attend in person but will join by telephone for the discussion of the R&D planning.]

11. Detector Concepts Four ‘concepts’ for ILC detectors have been proposed. Three are based on particle flow calorimetry and one is based on compensated (EM/Hadronic response equal) calorimetry. The GLD and LDC concepts are based on large TPC tracking. SiD is based on Si strip/pixel tracking. The concepts have rather decided regional flavor (SiD largely US; GLD largely Asian; LDC largely European). GLD and LDC are discussing joining together for letters of intent.

12. Reviewer Assignments: • Talk 1: Introduction: All • 2. Vertex detection: Bolton and Narain • 3. Jet energies: Cassel and Rijssenbeek • 4. Hadron Calorimetry: Rijssenbeek and Zhou • 5. Compensating Calor: Rijssenbeek and Narain • 6. EM Calorimetry: Narain and Rijssenbeek • 7. Gaseous Tracking: Zhou and Rameika • 8. Silicon Tracking: Zhou and Bolton • 9. Muon detection: Rameika and Zhou • 10. LEP-Beamline meas’ts: Cassel and Bolton • 11. Test beams: Bolton and Rameika • 12. Software development: Narain and Cassel • 13. R&D Plans: Rameika and Cassel

13. Closeout and Final Report • Closeout: Provide a short summary of your evaluation during the closeout tomorrow • Final Report: Each reviewer should provide a confidential statement that will serve as the basis for a written evaluation of the ILC Detector R&D Program by the DOE and NSF. JW and PG will compile and edit your comments into a Final Report. • Please provide your written report to JW and PG by Monday, June 29, 2007.

15. US support for ILC detector R&D substantially below that in Europe; probably somewhat below Asia. 2005 study by WWS generated support in hand and desired in various nations.

16. Organization • International World Wide Study (co-chairs J. Brau, F. Richard, H. Yamamoto) speak for and coordinate detector R&D. • The Americas subgroup of WWS is Americas Linear Collider Physics Group (ALCPG), co-chaired by Brau and Mark Oreglia. • This group coordinates the generic R&D activity on detectors. WWS is independent of GDE; informally, WWS reports to ILCSC, as does GDE.

17. WWS has proposed a letter of intent process: Call for Letters of Intent in summer 2007, due summer 2008. Select two detector concept designs to proceed to engineering design phase by end 2008. Detector EDRs in 2010, tied to the ILC accelerator schedule. • They also propose a Research Director, reporting to ILCSC, who will guide the detector LoI process, establish review mechanisms, facilitate needed generic R&D, work to secure resources, liaison with GDE on machine-detector interface, organize outreach activities.

18. WWS is conducting global R&D reviews in four main areas: Tracking (in Beijing, Feb. 2007, report on web page, Bing Zhou attended); Calorimetry (in DESY June 2007, Michael Rijssenbeek attended), Vertex detectors (in Fermilab in October), and Muon/PID/LEP in early 2008. • These reviews are intended to gather information, promote coordination and collaboration, help formulate priorities. The Tracking review report called for a coordinating body drawn from active participants to work toward common standards (test facilities, DAQ etc) and coordinate activity.
