Jupiter Laser Facility (JLF) Conduct Of Operations

The Conduct of Operations is a set of procedures and guidelines that are put in place to ensure operational safety and security.

The target areas contain a variety of potentially hazardous ultra-violet, visible and infrared lasers. Due to the complexity and scale of the laser beam paths, some beams are not enclosed. Accordingly, reliance is placed on engineering and administrative controls, and the use of proper laser protective eyewear.

Other potential hazards in the target areas may include ionizing radiation, high voltage, inert gases, high pressure gases, possibility of fire, and mechanical and electrical failures.

Guidance and advice on LLNL safety procedures and hazard control can be obtained from Bryan Mason, Hazards Control Environmental Safety & Health (ES&H) Team 3.

Normal Operating Procedures:

  1. Only persons who are registered as participants with approval by the JLF Operations Manager and the JLF Scientific Director are permitted to participate in Facility activities. The complete registration requirements can be found at the Participant Registration Procedure.

  2. Approval to perform an experiment in the JLF must be obtained from the Operations Manager and the Scientific Director prior to the commencement of the experiment.

  3. All approved scientific and technical work must be performed as scheduled in the JLF Calendar. For each experiment, only persons approved in the Experimental Team Registration are permitted to participate. The Registration is posted in the Janus Control Room.

  4. Each experiment is supervised by a Responsible Individual (RI) or a designated Alternative Responsible Individual (ARI).

  5. The RI or the ARI is to ensure that the number of persons in the target area is kept to a minimum and that proper protective laser eyewear is worn continuously by all persons in the target area while the laser beam hazard is present.

  6. Student Participating Guests must work under line-of-sight supervision by the RI, ARI, or a designated supervisor unless they have been granted exemption by Jupiter Laser Facility Operations.

  7. Only the RI, ARI or someone acting under their immediate supervision may request high-power laser shots into the target areas.

  8. The Janus, Titan and Callisto Target Areas must be evacuated before high-power shots are fired. In Titan, pre-shot evacuation must also comply with the search procedure for the area.
