Target Glass Thickness Measurements

Target Geometry information
(originally by Aidan Kelleher, re-entered by RJF)

Each of the cells used in the experiment was hand-blown by Mike Souza of Princeton University. Since they are hand-blown, there are variations in the thicknesses of the glass. The tables below are the result of measurements made at the University of Virginia.

A word about the measurements: the cells were measured in 12 places. The two end caps, and 5 points on each side. The points on each side are listed with respect to either the upstream or downstream end. Each table has the average from each side listed, and the summary table has the averages from each side of the cells, as well as the end window thicknesses.
