Once the β angle for the first (upstream) bundle support is set, derived from the the starting photon tag energy, each subsequent bundle support has a β angle offset from the previous one by a tow angle. Thus, as we look downstream from one bundle support to the next, the β angles differ by -(tow angle). Adjacent bundle supports will come in contact with one another at the SciFi end and form a triangular gap along their adjacent sides based on the tow angle.

An Excel [/nfs/direct/annex/mcintyre/TAGM-4-2021/Bundle-Support-4-2021.xlsx spreadsheet] has been created to calculate the location of the bundle supports' mounting rods with respect to the focal plane coordinate system. This spreadsheet also calculates the length of the parallel railing end supports which need to be fabricated anew for each unique TAGM location on the focal plane. One last, but very important thing that the spreadsheet calculates is the shim size needed during TAGM realignment in order to achieve the proper tow angle between bundle supports during mounting. In addition to the spreadsheet, AutoCAD drawings corresponding to a tagging energy spectrum starting at: [https://zeus.phys.uconn.edu/wiki/index.php/Student_Projects_in_Nuclear_Physics 11 GeV], [https://zeus.phys.uconn.edu/wiki/index.php/Student_Projects_in_Nuclear_Physics 10 GeV], [https://zeus.phys.uconn.edu/wiki/index.php/Student_Projects_in_Nuclear_Physics 9 GeV], [https://zeus.phys.uconn.edu/wiki/index.php/Student_Projects_in_Nuclear_Physics 8 GeV], [https://zeus.phys.uconn.edu/wiki/index.php/Student_Projects_in_Nuclear_Physics 7 GeV], [https://zeus.phys.uconn.edu/wiki/index.php/Student_Projects_in_Nuclear_Physics 6.5 GeV], [https://zeus.phys.uconn.edu/wiki/index.php/Student_Projects_in_Nuclear_Physics 6 GeV], [https://zeus.phys.uconn.edu/wiki/index.php/Student_Projects_in_Nuclear_Physics 5.5 GeV], and [https://zeus.phys.uconn.edu/wiki/index.php/Student_Projects_in_Nuclear_Physics 5 GeV] have been created. These CAD files contain the parallel railing system setup arranged for the corresponding photon energy range. These files are in US standard units (inches) and to scale with a tolerance of ± 0.001 inch.
