Guide tube is 7mm outer diameter
We added polyimide tape that was 150 microns thick before application
to the tube.
But a decent estimate would be the mechanical edge-to-edge orthogonal
separation between sensor edges 7.3 mm.
We need to add about 1 mm for the guard rings on each sensor
So the orthogonal gap between active pixels on opposing quads across
the beam guide tube should be 8.3 mm

Very rough estimate of the gaps
There are 3 types of gaps
All are active pixel to active pixel
sensor to sensor ~ 1.6 mm
CB to CB ~ 6.4 mm
sensor to CB ~ 3.9 mm
====
CB = Carrier Board edges

Weaver, Matt Tue 10/9, 3:07 PMO'Grady, Paul Christopher;Dubrovin, Mikhail;Damiani, Daniel S. Also, here's some description of the nominal geometry. Pay close attention to the last part that describes the positioning of ASICs within an "element". I think this might be different than before. -Matt // // Hard code the array's geometry for now // // (Epix10ka2m) // | // Quad 3 | Quad 0 Quad 1 is rotated 90d clockwise // -------+-------- Quad 2 is rotated 180d clockwise // Quad 2 | Quad 1 Quad 3 is rotated 270d clockwise // | // // (Quad 0) // | // Elem 0 | Elem 1 // -------+-------- No rotations // Elem 2 | Elem 3 // | // // (Elem 0) // | // ASIC 0 | ASIC 3 // -------+-------- No rotations // ASIC 1 | ASIC 2 // | |
