Write TSW

Experimenters must have a Technical Scope of Work (TSW), which describes the test experiment in detail. A TSW is a written plan put in place to establish a clear understanding of how an experiment will practically function and each party’s roles and responsibilities.

The preparation and consideration of a TSW for each test beam effort helps the facility be flexible and meet the goal of equal access to test beams for all detector tests with relatively low bureaucratic overhead and a guarantee of safety, coordination and oversight. The TSW is signed by the experiment spokesperson and acknowledged by Fermilab division heads and associate directors. The scope of work is not considered proprietary information and is publicly released.

The spokesperson is the experiment’s official contact and is responsible for forwarding all relevant information to the rest of the group, arranging for their training and getting the necessary approvals for the experiment to run.

The TSW maybe started from here. 

Most of the document needs to be filled in by the experimenter. Instructions are in green. Please use the tips below. Not all subsections are relevant for every experiment, and some experiments require additional subsections.

Examples: good, large effort or all.

Tips to avoid common errors

  • A TSW is a document between two parties. Words like “we” and “our” are inappropriate, typically being replaced by “the experimenters” and “the experiment’s.”
  • Experiment name should be limited to 30 characters.  Click here for acronym help.
  • Approximate, full, outside dimensions of space required for devices and equipment should be given explicitly.
  • In Section 2.2.2, include the radiation length of all the material that will be in the beam.
  • Please include requests for facility equipment such as instrumentation, motion tables, or helium tubes in Section 4.2. Some equipment needs extra time to be calibrated or installed.
  • Be sure to take into account the scheduling guidelines.
  • If there are items that will be accomplished by Fermilab collaborators, independent of division/sector/center, Section 4.5 can be added, titled Fermilab collaborators and the items to be contributed, as well as staff effort can be listed there. These numbers should be included in the Section V table.
  • If there are two spokespeople, they are called co-spokespeople and both sign the signatures page. If one is spokesperson and the other is a deputy spokesperson, only the spokesperson signs. Please adjust Section VI accordingly.
  • The first draft is not the final draft. You are encouraged to submit a first draft, as complete as possible, as soon as possible. If there is some detail of information you are waiting for, there are several rounds where details will be added in afterwards.

For the appendices

  1. A PowerPoint file of the MTest areas is available here. Please use it to create a jpg showing where you would like to put your apparatus, and then include approximate weight and dimensions. It is highly recommended you include as many pictures of your apparatus as possible, including photos, diagrams, mechanical drawings, etc. Pictures of apparatus and set-up are greatly appreciated and will improve the Operational Readiness Clearance process.
  2. The Physics Research Equipment Pool (PREP) provides and supports electronic instrumentation for high-energy physics research, according to their PREP procedures. For more information see Equipment Logistics Services.
  3. The Hazard ID Checklist MUST be the last page of your TSW. It is included in the template.
    • For an explanation of the categories on this checklist see the ORC web page.
