  • Old Lujan Target removed and placed in storage as a low-current spare, and new Lujan Target installed
  • Integrated shielding package installed on FPs 11, 12, 13
  • New redundant personnel protection system on all flight paths
  • New mercury shutter reservoirs for older flight paths, with upgraded piping and sensor systems
  • Computerized control of all shutters, with data available in the Central Control Room
  • Data acquisition conversion of User Program instruments done
  • ASTERIX instrument rebuilt
  • NODF (Formerly Neutron Powder Diffractometer) upgrade underway

Based on number of users on scheduled proposals in CY2003-2003 compared with users in CY2001

*

We are expanding the size and quality of our user program consistent with our strategic plan and previous BESAC recommendations
  • Deliver beam at 100 µA with >75% availability for 2616 hours for user program, supplemented by 336 hours for instrument tune-up and 384 hours of contingency
  • Limit beam down-times longer than 8 hours to <10% of scheduled time
  • Deliver 95% instrument reliability
  • Increase sample environment support
    • 11T Magnet
    • Cryofurnace
    • More staff support
  • Increase user base* by 15%

We made major progress in 2001 towards establishing a significant user base at Lujan Center

Provide a single Steward of this facility

Develop an adequately-funded, actionable implementation plan for FY2002, sustainable over the period 2002-2008

Specify a ramp-up schedule for LANSCE/Lujan to full functional status by FY 2003

Increase the LANSCE/Lujan user base to ~1000 by 2006

Responsibility assigned to NNSA, Executive Council established

Completed externally and internally peer-reviewed bottom-up cost estimate for LANSCE

Completed as part of cost estimate. Funding increment of $10M in 2003 LANSCE operations budget

Began process with successful CY2001 operating cycle - 270 user visits, 150 unique users

We are aggressively implementing the November 2000 BESAC recommendations in our operations and governance

Recommendation

Action

summary
Summary
  • In 2001 LANSCE completed an excellent scientific program at all facilities with the largest number of users to date
  • Proposals for LANSCE use in 2002 were evaluated and an operations schedule was developed using lessons learned from 2001
  • LANSCE completed an aggressive, well-managed outage on schedule and is operational
  • The Mark-I Lujan target-moderator-reflector system has been moved to storage and is available as a 55 µA backup
  • The Mark-II Lujan target-moderator-reflector system has been installed and is operational at 100 µA
  • The Switchyard Kicker project is proceeding well and the equipment will be installed and commissioned in 2003
  • The Lujan Center user program will start on July 26, 2002 and run until January 26, 2002.
