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



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



LANSCE/Lujan Impact: -

Modest impact compared with resources

Overshadowed by IPNS

But

Broad range of Competencies on the Mesa

20.48 s 21.55 s 22.63 s 23.70 s

GENIE PRAD

Lujan has great potential…. …..for both internal + external programs



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



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



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
