Facility Evaluation Andrew Taylor BESAC Subpanel Review of IPNS and LANSCE/Lujan Center Figures of Merit

Facility Evaluation Andrew Taylor BESAC Subpanel Review of IPNS and LANSCE/Lujan Center 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

Facility Evaluation Andrew Taylor BESAC Subpanel Review of IPNS and LANSCE/Lujan Center 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

Facility Evaluation Andrew Taylor BESAC Subpanel Review of IPNS and LANSCE/Lujan Center LANSCE/Lujan Impact: - Modest impact compared with resources Overshadowed by IPNS But Broad range of Competencies on the Mesa t =  s19.41  s  s  s  s  s  s GENIEPRAD Lujan has great potential…. …..for both internal + external programs

Facility Evaluation Andrew Taylor BESAC Subpanel Review of IPNS and LANSCE/Lujan Center 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

Facility Evaluation Andrew Taylor BESAC Subpanel Review of IPNS and LANSCE/Lujan Center 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

Facility Evaluation Andrew Taylor BESAC Subpanel Review of IPNS and LANSCE/Lujan Center 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
