Comments on epix10ka2m geometry from Chris Kenney

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

and 352 orthogonal to the balcony (vertical direction)

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.

Here's the geometry I'm now using (below).  Note that pixel(0,0) 
for each of the elements below is in the lower right hand corner.
We'll know the quadrant layout for sure when we get the radioactive source exposure on Monday.

The ASICs did not move. The change is that the (352,384) 
array has pixel (0,0) in the lower right hand corner (in ASIC2).

Hi Mikhail,
We took radioactive source test
 runs today to verify the geometry.  We found that we were rotated by 90
 degrees, which matches the labeling on the back of the detector as well
 as the metrology picture from Chris Kenney. 
The runs are 
/reg/d/psdm/det/detdaq17/e968-r0131   - source unmasked (up to ~ event 10000), then masked vertically after ~ event 15000
/reg/d/psdm/det/detdaq17/e968-r0132   - source masked horizontally at bottom after ~ event 15000.

So, the picture is...
  //  (Epix10ka2m)
  //         |
  //  Quad 0 | Quad 1      Quad 2 is rotated  90d clockwise
  //  -------+--------     Quad 3 is rotated 180d clockwise
  //  Quad 3 | Quad 2      Quad 0 is rotated 270d clockwise
  //         |
  //
  //  (Quad 1)
  //         |
  //  Elem 0 | Elem 1
  //  -------+--------     No rotations
  //  Elem 2 | Elem 3
  //         |
  //
  //  (Elem 0)
  //         |
  //  ASIC 0 | ASIC 3
  //  -------+--------     No rotations
  //  ASIC 1 | ASIC 2
  //         |
  //
  //  (Elem 0-3 pixel array)
  //                    row increasing
  //                          ^
  //                          |
  //                          |
  //  column increasing <-- (0,0)
