Call for Proposals: Radiation Effects at LANSCE 2024 Run Cycle
The Los Alamos Neutron Science Center (LANSCE) is issuing a Call for Proposals for Radiation
Effects work at the Weapons Neutron Research (WNR) Facility for the upcoming run cyclefrom September 3, 2024 to December 22, 2024.
The LANSCE/WNR call for Radiation Effects proposals is now open.
Deadline for proposals: Monday, April 22, 2024 5:00 pm (MDT)The WNR facility provides neutron and proton beams for radiation effects research. Neutronbeams with energies ranging from about 0.1 MeV to more than 600 MeV are produced inTarget 4 (an unmoderated tungsten spallation source) using the 800 MeV proton beam fromthe LANSCE LINAC. The 30-deg flight paths (ICE-I and ICE-II) provide a neutron spectrum that isvery similar to the neutron spectrum produced by cosmic rays striking the atmosphere.
In the Target-2 area (Blue Room), samples can be exposed to the proton beam with energies
up to 800 MeV either from the LINAC or the proton storage ring (PSR).
Information about the flight paths is available athttps://lansce.lanl.gov/facilities/Radiation%20Effects/index.php

Neutron Radiation Effects Proposals
When requesting access to the semiconductor irradiation and testing facilities, please specify
which flight path is your first choice (ICE-I or ICE-II).
Note that users planning full cost recovery experiments must also submit a proposal by
selecting the “Industry Call” in the LEMS system (see below). These proposals are not reviewed
by the Program Advisory Committee (PAC). For technical questions contact Steve Wender(wender@lanl.gov, 505-667-1344). For questions regarding full cost recovery experiments andfor administrative questions regarding contracts for these experiments, please contact Valerie
Salazar (vsalazar@lanl.gov, 505-667-6797). Beam time allocation for full cost recovery
experiments on any beamline is determined on a first come, first served basis and proposals are
accepted at all times.

Standard (not paying full cost) Neutron Radiation Effects Proposals
The Radiation Effects subcommittee of the PAC will review all the beam time proposals forradiation effects experiments on electronics, materials, and instruments. Experiments thatinvolve detectors that have ultimate use for basic nuclear physics may be reviewed by the Basic
Nuclear Physics subcommittee and proposals having a strong programmatic motivation may bereviewed by the Defense PAC.

Note: The LANSCE cost model can now be found at https://lansce.lanl.gov/users/become-auser/user-agreements.php , where experiments are separated into three categories. If you havequestions regarding which category your experiment would be, please contact Steve Wender(wender@lanl.gov, 505-667-1344)

Timeline
The deadline for proposal submission is Monday, April 22, 2024, at 5:00 pm (MDT).
The Rad Effects PAC will meet the week of May 6, 2024.

Proposal Submission and Selection
Proposal Submission and Required Documents
All proposals must be submitted using the LANSCE Experiment Management System (LEMS):
https://lems.lanl.gov/login.
For proposals that will be reviewed by the PAC, proposers will be expected to give a 10-minutepresentation to the PAC with 5 minutes for questions. The PAC will arrange a time for thepresentation.
DOE requires that all personnel planning to visit LANSCE be listed in the proposal.
Please, contact the User Program Office, lansce-user-office@lanl.gov or 505-667-6797 forassistance with the proposal process or the instrument scientist for technical questions.

Program Advisory Committee Review
Proposals that are incomplete, or that did not follow the formatting guidelines, will not bereviewed and will not be recommended for beam time.
The proposals will be reviewed by the Instrument Scientists to determine their compatibility
and feasibility at the facility and by the PAC to be ranked based on their scientific merit. The
PAC is an advisory committee to the LANSCE User Facility Director (LUFD) and is composed oftechnical experts in the relevant field. It will judge the proposals based upon the criteria statedbelow:
1.
2.
3.
4.

The quality of the science or measurement being proposed.
The impact of the science or measurement being proposed.
The feasibility and readiness of the proposed experiments.
The need for LANSCE resources.

The PAC will provide a grade for the proposals along with recommendations for which
proposals should be awarded beam time. The LUFD and representatives from the programs
sponsoring experiments at LANSCE will then schedule beam time. PAC feedback will be
provided for all proposals in a timely manner, no later than the beginning of the LANSCE runcycle.

What to expect if your proposal is accepted.
Proposal SchedulingOnce the LANSCE accelerator operating schedule for the run cycle is finalized, the Instrument
Scientist for each flight path will combine that operating schedule with the PAC grades in orderto develop a draft schedule for each area or flight path. These schedules will be communicatedto experiment proposers as soon as possible so that you will then be able to makearrangements for the visit, shipment of equipment, user travel, etc.
Final scheduling of ranked proposals depends upon the feasibility of fielding the experiment
within the constraints of the LANSCE operating schedule. Because of the complexity of theLANSCE accelerator and experimental system, the operating schedule may change over thecourse of the run cycle, and thus, particular experimental dates cannot be guaranteed.
Note: The Department of Energy (DOE) requires users of any LANSCE Facility to have a User
Agreement (UA) in place between Los Alamos National Laboratory and the user’s homeinstitution before the experiment can be run. The description and list of existing UA can befound at https://lansce.lanl.gov/users/become-a-user/user-agreements.php. If your institution
does not have a valid UA in place, please contact the User Office at lansce-user-office@lanl.govto start the process as early as possible.

Proposals which were recommended for beam time but not executed in a given run cycle must
be resubmitted for a later run cycle. The PAC will note the previous recommendations andaccordingly grade them highly if they were not executed due to problems with the LANSCE
accelerator.

Obtaining access to LANL••All visiting users must register three weeks before the scheduled experiment. Non-UScitizens must register at least 60 days before their visit. US citizens must bring a picture ID(Driver’s license) and proof of citizenship (Passport or Birth Certificate).
DOE requires additional information to grant non-US citizens access to Los Alamos National
Laboratory (LANL). Foreign national visitors must have an approved visit request, present avalid passport and documentation of US legal status and work authorizations.
