Chapter 3120 The CEBAF Experiment Review Process


Jefferson Lab holds the strong conviction that high standards in environment, safety, and health (ES&H) are fully compatible with accomplishing forefront research. The laboratory’s ES&H Policy states that "Jefferson Lab considers no activity to be so urgent or important that we will compromise our standards for environmental protection, safety, or health."

To help ensure that safety is integrated into the planning and conduct of experiments Jefferson Lab has established an experimental review process. By including safety considerations in the early design stages of an experiment the experimenter reduces the risk that safety issues, that could significantly delay the experiment, will surface later.


This review process is performed for all experiments mounted in the experimental halls at Jefferson Lab, and may be used for the review of "special" experiments using other capabilities of the laboratory.

A separate ES&H Manual Chapter 3130 Accelerator Experiment Safety Review Process applies to experiments based at the LERF.

  • Jefferson Lab expects ES&H concerns to be integrated into the planning and conduct of each experiment.
  • Experimenters are expected to work within the ES&H requirements of the ES&H Manual at all times. Experimenters, like staff, have the authority and responsibility to stop work for conditions that pose imminent hazard or danger.
  • ES&H professionals are an important resource for experimenters and should be consulted when safety issues arise.
  • Steps in the experimental review process include:
    • Proposal Phase
    • Approved Proposal: Preliminary Planning Phase
    • Design Phase
    • Construction Phase
    • Scheduling of Experiment by Jefferson Lab
    • Equipment Installation
    • Preparation for Running the Experiment
    • Commission equipment
    • Run the Experiment
    • Decommission equipment (if appropriate) and store or dispose of target and/or contaminated apparatus properly
Phases of the CEBAF Experiment Readiness Review Process are found in the Readiness Review Process - Flowchart (click on the applicable box for details on the respective phase).

The CEBAF Experiment Readiness Review Process is reviewed and approved in conjunction with this ES&H manual chapter, similar to appendices documents, as defined within ES&H Manual Chapter 1300 Content Review Program.
