  13. LANSCE/Lujan Reliability: - BESAC Subpanel Review of IPNS and LANSCE/Lujan Center

  14. Lujan Reliability Taking a Systematic approach but Ageing systems need investment BESAC Subpanel Review of IPNS and LANSCE/Lujan Center

  15. IPNS Reliability: + + Outstanding -- for now ! BESAC Subpanel Review of IPNS and LANSCE/Lujan Center

  16. Comparison 687 BESAC Subpanel Review of IPNS and LANSCE/Lujan Center

  17. FDS SCD HIPD  SPEAR LQD CNR  PHAROS NPD 1 square =1 m 0 m 20 m Lujan Instrumentation: - Instrument Suite -- 6/7 Good in Parts Instruments in User Program - 3 World Ranking BESAC Subpanel Review of IPNS and LANSCE/Lujan Center

  18. Lujan Successes NPD Advanced Engineering Materials Diffraction from NiTi under load. BESAC Subpanel Review of IPNS and LANSCE/Lujan Center

  19. Lujan Problems PHAROS MAPS LANSCE should be competitive with ISIS BESAC Subpanel Review of IPNS and LANSCE/Lujan Center

  20. Making MAPS of Magnetism first science from the new ISIS spectrometer BESAC Subpanel Review of IPNS and LANSCE/Lujan Center

  21. New Science at ISIS Broholm et al Mook et al BESAC Subpanel Review of IPNS and LANSCE/Lujan Center

  22. USA at ISIS BESAC Subpanel Review of IPNS and LANSCE/Lujan Center

  23.     IPNS Instrumentation: - - Well balanced Instrument Suite - Useful Research Tools - Despite severe under investment World Class Science BESAC Subpanel Review of IPNS and LANSCE/Lujan Center

  24. IPNS - World Class Science Magnetic structures in the CMR manganites: the pseudo-2D system La2-2xSr1+2xMn2O7C. D. Ling, J. E. Millburn, J. F. Mitchell, D. N. Argyriou, J. Linton, H. N. Bordallo, Phys. Rev. B 62, xxxx (1 Dec 2000) BESAC Subpanel Review of IPNS and LANSCE/Lujan Center

  25. IPNS Developments Highly cost effective eg QENS x 10 for $700k Much potential…. Testbed for SNS BESAC Subpanel Review of IPNS and LANSCE/Lujan Center

  26. Lujan Support Facilities: - • Ranked well by user community • Needs improvement IPNS Support Facilities: - • Benefits from MSD infrastructure • Significant under-investment BESAC Subpanel Review of IPNS and LANSCE/Lujan Center

  27. Lujan Support Staff: + • Dedicated and committed • Accelerator understaffed • 3.9 staff / instrument ~ISIS IPNS Support Staff: + • Dedicated and committed • Accelerator understaffed • 2.7 staff / instrument < ISIS BESAC Subpanel Review of IPNS and LANSCE/Lujan Center

  28. Exploded view of HIPPO 150° 1384 detectors 4.6 m2 90° 40° 20° 10° HIPPO Lujan Users: + Significant potential Enthusiastic despite setbacks SDT concept successful in involving UC Campuses BESAC Subpanel Review of IPNS and LANSCE/Lujan Center

  29. World Class Instruments GEM BESAC Subpanel Review of IPNS and LANSCE/Lujan Center

  30. IPNS Users: + • Internal Program in MSD • - Outstanding Quality • Strong commitment at all levels in the organisation to the concept of a User Facility • Enhancement plan to develop the user base BESAC Subpanel Review of IPNS and LANSCE/Lujan Center

  31. LANSCE / Lujan Cost Effectiveness Operations (marginal): - Operations (average) : - - Cost Effectiveness Science (marginal): + Science (average) : - see table BESAC Subpanel Review of IPNS and LANSCE/Lujan Center

  32. IPNS Cost Effectiveness Operations: + + Cost Effectiveness Science: + see table BESAC Subpanel Review of IPNS and LANSCE/Lujan Center

  33. Figures of Merit BESAC Subpanel Review of IPNS and LANSCE/Lujan Center

  34. LANSCE Stewardship: - - Performance far below potential Grossly inadequate Lujan Operation No correlation between articulated priorities and funding flow Lack of focus - over a prolonged period of time - and still ongoing Multiple sponsors - no single champion No clearly identified action plan at the highest levels in LANL and in DOE BESAC Subpanel Review of IPNS and LANSCE/Lujan Center

  35. IPNS Stewardship: + • Well integrated team • Internationally acclaimed • Committed to running a user facility • Enthusiastically embracing SNS • Truly Outstanding • but • Let down by lack of support by DOE BESAC Subpanel Review of IPNS and LANSCE/Lujan Center

  36. 18.33 s 19.41 s 17.26 s t = 0 20.48 s 21.55 s 22.63 s 23.70 s LANSCE/Lujan Impact: - Modest impact compared with resources Overshadowed by IPNS But Broad range of Competencies on the Mesa GENIE PRAD Lujan has great potential…. …..for both internal + external programs BESAC Subpanel Review of IPNS and LANSCE/Lujan Center

  37. IPNS Impact: + Reservoir of expertise Track record of seminal developments second to none High international stranding of staff in both IPNS and MSD Outreach to build a community particularly praiseworthy but Impact moderated by source strength and lack of investments in instrumentation BESAC Subpanel Review of IPNS and LANSCE/Lujan Center

  38. LANSCE/Lujan Summary Potential to be a world ranking user facility Latent user community - both internally and in the UC Campuses Staff on the Lujan floor and in the SDTs show promise Evidence of commitment at all levels but Lack of integration renders this ineffective BESAC Subpanel Review of IPNS and LANSCE/Lujan Center

  39. IPNS Summary Outstanding value Impressively well integrated team keeps an outmoded source operational at the highest levels of efficiency Can be sustained and enhanced -- with modest investments Plan for cost effective upgrades identified Window of opportunity to pass on expertise to a new generation Committed to success at all levels BESAC Subpanel Review of IPNS and LANSCE/Lujan Center
