Items for followup from previous meeting

1. Ship Baby Bcal to USM.
2. Alam (Pedro) to post files for new geometry of light guides.

Documents to Review

1. Media:Draw trigs 38deg.pdf Media:Draw trigs 73deg.pdf for segment #2.
   • Entrance rectangle is 3.01x4.0 cm. Exit radius is 1.35 cm. Length of trapezoid/cone is 60 cm, and length of torus is also 60 cm.
   • This configuration should be comparable to Alam's "cylindrical cone" geometry.
2. See also Effective diameter vs B field and angle from Antonelli et al., NIMA 368 (1996) 628-634.
3. Magnetic field plots
   • Media:Plot bfield tot downstream.png
   • Media:Plot bfield theta downstream.png
   • Media:Plot bfield tot upstream.png
   • Media:Plot bfield theta upstream.png
4. Light guide prototypes. See Quote from Plastic Craft and Ray tracing through light guides
