#* One important point is that rails cannot accommodate all 17 bundles. Only bundles 1-16 willl fit. This results in having 96 microscope columns instead of 100. However, this will provide sufficient coverage for CPP.

##* James asked if space in the ESB could be made available in case unexpected procedures were required. Mark: Space itself is not a problem but activities might require a Work Control Document, depending on the activity. James: This is not anticipated and any procedures would not anticipate any special hazards.
−
#* James' calculations for the microscope were referenced to yc=0, whereas the coordinate designation indicates they should be at yc=-0.9 cm, which Elton used in his calculations
+
##* After updating with final changes, James will upload the document to docDB for reference
−
#* James will update the calculations and generate locations for the microscope with a maximum energy of 6.2 GeV. These will be compared to Elton's numbers. Once any discrepancies are resolved, the drawings can be updated and the 3 new alignment pieces will be ordered in preparation for the move.

## Comments (Richard)

##* Requests that the microscope be located so that connections to electronics can be made for testing and verification, even if the microscope itself not be in its final location.

##* Survey of the microscope will also be required. Tim will request survey help for Monday Jan 10.

  1. Previous CPP meeting: Apr 12, 2021
  2. Announcements
    • Beam delivery to Hall D is expected to end on Dec 20. [Note added: Elton checked with Eugene and he confirmed that there will be no beam to Hall D in January]
  3. Updates on design (James)
    1. Jim has prepared extensive writeup documenting how to move the tagger microscope to a new location.
      • He highlighted important parts of the document.
      • Included in the document is a list of items that JLab needs to provide to support the move, including tables for staging equipment, stools/chairs to be used during alignment, shop vacuum and HEPA filter, etc. The document will include a full list and specification of required equipment.
      • James requested that the microscope be moved out past the hodoscope to allow access from all sides to make the necessary modifications. Tim will coordinate that effort in Jan and should be completed by Wed Jan 5.
      • James asked if space in the ESB could be made available in case unexpected procedures were required. Mark: Space itself is not a problem but activities might require a Work Control Document, depending on the activity. James: This is not anticipated and any procedures would not anticipate any special hazards.
      • After updating with final changes, James will upload the document to docDB for reference
    2. Comments (Richard)
      • Requests that the microscope be located so that connections to electronics can be made for testing and verification, even if the microscope itself not be in its final location.
      • Survey of the microscope will also be required. Tim will request survey help for Monday Jan 10.
