For Lujan Users
The User Program at the Lujan Center will resume 9th January, 2013 and continue to 2nd March, 2013 on the following instruments; NPDF, SMARTS, SPEAR, LQD, Asterix, and PCS. We expect to resume a full User Program (including HIPPO, FDS and HIPD) in the summer of 2013. All experiments that were recently postponed will be rescheduled in 2013. Priority for January through March operation will be determined by the experimental review committee (MPAC) score and by constraints of our interim resumption plan.
For the January through March run cycle the Lujan Center will operate using conservative procedures that control for the vulnerabilities that came to light as a result of the recent contamination event. Our goal is to provide the best service that we can during an interim period of operations interim rules as we continue to refine the ergonomics to ensure safe and secure operations. We ask you for your continued support in this critical interim phase of operation.
We would like to thank the DOE, NNSA, LANL, NSSA and all the users who helped us during the closure and for the contributions that they have made that lead to the resumption of our user activities.
We are very much looking forward to hosting Users in 2013. We wish you a happy and safe holiday season.
Many Thanks,
The Lujan Center
The Lujan Neutron Scattering Center at Los Alamos National Laboratory is a national user facility funded by Basic Energy Sciences of the Department of Energy. Neutron scattering instruments are available to qualified scientists worldwide with time allocated based on a proposal system. There are two proposal deadlines each year.
The Lujan Center instruments operate in time of flight mode receiving neutrons from a tungsten spallation target and the LANSCE proton accelerator, which operates at an energy of 800 MeV with typical beam currents of 100 – 125 microamps. At a pulse rate of 20 Hz, the instruments view moderators optimized for each specific beamline. The facility operates for a total of 3,000 hours per year.
User research at the Lujan Center is focused in four science thrust areas. Each has a contact person who is available to discuss proposed experiments and to provide advice on the appropriate instrument and instrument scientist, available sample environments, and other details for planned experiments. New users especially are urged to contact the appropriate instrument scientist before submitting a proposal.
The neutron scattering instruments are augmented by a fully equipped chemical preparation laboratory, clean room, and various analytical tools including an x-ray lab.
A variety of sample environment equipment is available including low temperature (down 15-20 mK), high temperatue (> 1000 C), high magnetic fields, and fluid and anvil cell pressure capabilities.
The Lujan Center users and internal scientific staff annually publish 125 – 150 articles in peer reviewed publications, many of which are in high profile journals. The list of 2010 papers is available.
Publication Notice: When a paper is submitted for publication that involves research at the Lujan Center please include the statement:
"This research was performed on the (name) instrument at the Lujan Center at Los Alamos National Laboratory supported by DOE-Basic Energy Sciences under FWP #2012LANLE389."
We will also appreciate your sending a PDF copy of all current published papers involving the Lujan Center to the respective instrument scientist.
