Tagger Microscope Mechanical Design

Page under construction.

A light-sealed enclosure for the Tagger Microscope is under design. The following requirements have been set forth to constrain it:

• hermetically sealed from light
• if possible ability to work at all usable energies (not just ~9 GeV of GlueX)
• motorized internal 3-point adjustment to bring the fiber array plane to appropriate alignment with that of the electrons
• plan for SiPM bias and amplifier board alignment to fiber waveguides (out of the electron plane)
  • appropriate room for bending these stiff 2 mm square fibers
• pulser assembly for testing the Tagger without beam
• clearance from all structural elements in front of the scintillators to avoid multiple scattering and bremsstrahlung as well as minimal material downstream of the scintillators

Solutions to these is discussed below.
