Collab 5/26/06 #5 EDMEDM Crucial Points to Agreement Project name is now nEDM R&D establishes technical feasibility prior to CD-2 NSF a major partner Cryogenic physicist at ORNL Delays to slow controls and beam guides CD-2 requirement on sensitivity – 30 x 10 –28 e·cm CD-4 completion requirements Cost $ $4.2 = $19M AY$ The CD-1 documents will be on the web once they are finalized

Collab 5/26/06 #6 EDMEDM CD-4 Requirements Distributed Completion Integrated Tests Cryogenic vessel installed at ORNL  Demonstrated to cool the central detector volume to 500 mK  Operated with the magnet coil package, central insert and 3 He services in place Central detector insert installed and cryogenically integrated at ORNL but the following requirements met at LANL  High voltage holds  5 kV/cm with a leakage current < 10 nA  Mean number of photoelectrons from 750 keV of energy deposition is  4  SQUID noise 1  Neutron storage time in similar cell demonstrated to be >100 sec in an independent test Magnet coil package installed and cryogenically integrated at ORNL  /B 0 < /cm at 77 K achieved at Caltech

Collab 5/26/06 #7 EDMEDM CD-4 Requirements Four-layer magnetic shield in storage at Caltech or ORNL  Shielding factor of achieved at Caltech The shields will be installed post project at a time when needed technically. Premature installation will endanger the shields and delay progress towards science because they would be a hindrance to other required operations. 3 He services installed and cryogenically integrated at ORNL but the following requirements met at LANL or Illinois  Produces  /cm 3 of  70%-polarized 3 He in the collection volume as seen with a SQUID  Purifier reduces the 3 He concentration to less than 1 part in  3 He demonstrated to move between volumes with a time constant of 500 sec  Valves shown to operate over 500 cycles Neutron guides installed at ORNL except for the final two meters  Flux out/MW  2x10 6 n/A/cm Å with a polarization  70% An evaluation of the overall sensitivity to be better than 300 x 10 –28 e·cm

Collab 5/26/06 #8 EDMEDM Continuing Resolution Congress will either pass A continuing resolution A budget In either case, the likelihood is no new starts EDM construction is a new start Any more funds in FY’07 are likely OPC, i.e have limited but creative usage Have received $430k this year for R&D and the project office Of the remaining $870k+$110k, DOE may give ~$400k NSF might give $110k or more

Collab 5/26/06 #9 EDMEDM Town Meeting for the Long Range Plan Chicago, January 18-21, 2007 From “Fundamental Symmetries and Neutrino Physics” topical subfield, nEDM got essentially a stand alone recommendation in second place behind DUSEL Likely to result being mentioned as a new initiative in the executive summary of the long range plan Importance to the DOE is unclear Impressive and important to the NSF
