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

so 384 columns parallel to the balcony (the widest dead gaps)
and 352 orthogonal to the balcony (vertical direction)
