CY2001 Run Cycle CY2002 Outage CY2002-CY2003 Run Cycle Summary Outline

Lujan Neutron Scattering Center Weapons Neutron Research Facility Proton Radiography 800 MeV Proton Linear Accelerator LANSCE is a unique multidisciplinary facility for science and technology with three operational user facilities

Lujan Center had a highly successful run cycle in 2001 Delivered 2499 hours, or 131% of our goal of 2735 hours at 75% availability Delivered an integrated charge of 83% of our goal with 54 µA average current Performed 113 user experiments with 91% reliability of beam delivery and over 95% instrument availability Supported 270 user visits, 150 unique users Commissioned five new scattering instruments and one nuclear science instrument; –SMARTS, HIPPO, PROTEIN, PHAROS (Rebuilt), and ASTERIX –DANCE Developed and implemented a new generation of data acquisition and chopper control systems. Obtained approval for actinide experiments. Lujan Center Materials Science Characterizing Components and Materials Plutonium Science Highlights:

LANSCE has established an operations schedule for that is similar to 2001 Major milestones for the CY2002 schedule –December 24, 2001Cease CY2001 operations –January 2, 2002Begin CY2002 outage (17 weeks) –April 22-23Materials Program Advisory Committee Review Meeting –June 1Schedule Published on Web –May 1, 2002Begin CY user facility turn-on (37 days) –May 27, 2002Begin Proton Radiography operations –June 3, 2002Begin Proton Storage Ring operations –June 19, 2002Begin WNR Low-power operations –July 7, 2002Begin Lujan Center tune-up –July 26, 2002Begin scheduled user facility operations –January 26, 2003Cease CY operations

The Lujan outage schedule in CY2002 was aggressive and completed in time to start user program 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 NPD before major surgery FP 12 & 13 are ready for beam

The Mark-II TMRS design with stainless steel and beryllium reflectors is installed and operational at 100 µA Beam window and guard ring Middle beryllium reflector Upper SST reflector Lower flight path liners and water moderators Service Connections Beam Diagnostic Lower Be/SST composite reflector LH 2 Moderator Upper tungsten target 3m

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% * Based on number of users on scheduled proposals in CY compared with users in CY2001 Number Year We made major progress in 2001 towards establishing a significant user base at Lujan Center

We are aggressively implementing the November 2000 BESAC recommendations in our operations and governance Provide a single Steward of this facility Develop an adequately-funded, actionable implementation plan for FY2002, sustainable over the period 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 user visits, 150 unique users RecommendationAction

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.
