  • Familiarize yourself with visiting LANSCE.
  • Minor non-LANL users are prohibited to come onsite for an experiment.
  • Coordinate the remote LANL badging process with the LANSCE User Office.

Coordinate your experiment with the User Office

  • You will be notified of your experiment schedule at least 3-6 weeks prior to your start date.
  • It is important that you contact your instrument scientist as soon as you receive your experiment start date.
  • Discuss any shipment of equipment and samples with the instrument scientist and User Office prior to shipment and notify both once you receive delivery notice.
  • If you need a special sample holder or ancillary equipment, please make arrangements with your instrument scientist before your experiment start date.
