Hall C Futures

General Guidelines

  • Each section must consistent with the other sections.
  • Every reference must be verified, and duplicates resolved.


  • I. Introduction
    • Editors: Bogdan, Mark, Tanja
    • Guidelines:
      • Introduction to what the document is about - the identity of Hall C in the EIC era
      • Brief overview of the physics need for overall progress of the field - what's needed for specific studies of hadron structure which will then lead to the next chapter of how Hall C addresses this need
  • II. Hall C Futures Physics Program
    • Writers: (needs writers first, editors later!) Ed, Garth, Carlos
    • Editors: Bill
    • Guidelines:
      • this is the key piece of the document that should discuss the Hall C Future, i.e., precision, small cross section measurements with versatile equipment.
      • This chapter should contain material like:
        • Small, precision cross sections have been the main theme of Hall C since the start - give a few examples from 6 GeV and have extended into 12 GeV - also give a few examples - and
        • refer to Chapter IV where further details can be found In the EIC era expect to take advantage of positrons and energy upgrade that would enable new physics with small cross sections in Hall C and also extend its small cross section physics program
  • III. Overview of the Hall C Facility
    • Editors: Dave G?, David H
    • Guidelines: this chapter provides an overview of the different configurations of the Hall C facility and should include all instrumentation now and envisioned.
  • IV. A Sampling of Potential Hall C Experiments
    • Editors:DD, David H, Arun
    • Guidelines:
      • this chapter will present the details on experiments with small cross sections and/or versatile equipment mentioned in Chapter II.
      • How to handle 6 vs 12 vs 22 GeV? - one possibility discussed: three paragraphs where one focuses on 6 GeV (what has been done), the next on 12 GeV (what is being done now), and the third on future (opportunities with higher energy, etc.) All of these should be consistent with the overall goals of the Hall in the introductory chapters 1+2 - basically provide a coherent theme of Hall C
  • V. Potential Significant Upgrades
    • Editors: Jay
    • Guidelines:
      • that we can refer to it in Chapter IV for the physics.
      • this chapter is a little out of place as it is Lab-wide upgrades.
      • I would leave it here for now, but the physics should go under Chapter IV. 
      • We may consider moving the technical discussion of Positrons and 22 GeV as an appendix
  • VI. Summary
    • Editors: Dave M., Tanja
    • Guidelines:
      • Summarize the identity of Hall C emphasizing the coherent program to address specific physics needs of the field and unique strengths of the Hall
