**Outline**

## LANSCE is a unique multidisciplinary facility for science and technology with three operational user facilities

**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.**

**Highlights:**

## LANSCE has established an operations schedule for 2002-2003 that is similar to 2001

**Major milestones for the CY2002 schedule**

## 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

- LH2 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%**

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

## Rotation model for CY2002-2003 user program in neutron scattering maximizes the number of instruments

- NPD

- SMARTS

- HIPD

- HIPPO

- SCD

- SPEAR

- LQD

- PROTEIN

- Full Support for User Program

- 4 FTE

- 0.5 FTE

- Institutional & Friendly User Support

## Beam delivery to Lujan will increase 25% after installation of a switchyard kicker system during the CY2003 outage

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

**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 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**

**Recommendation**

**Action**

## 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.**

## Instrument throughput: users per instrument in FY2001

- Fig. 8 in OSTP Report on *Needs of Major Neutron Scattering Facilities & Instruments* in the US (FY00).

- OSTP report uses ~4, actual data is 6.3 (25 users/4 instruments run in 2000)

**Instrument throughput: users per instrument in FY2001**

**Notes:**
Notes:

The graph in the OSTP report is based on 6 instruments in FY2000.  However, only 4 instruments were operated for the user program (due to funding) in FY2000, so the number should be based on 25 users/4 instruments.  

## Number of research facility support staff (includes staff that support use and instrument ops, but excludes support of source operations)

- Fig. 12 in OSTP Report on *Needs of Major Neutron Scattering Facilities & Instruments in the US* (FY00).

- OSTP report indicates ~38, actual data is 21.
