1) BASICS:
* ALL THE FOLLOWING PICTURES ARE AS VIEWED FROM BEHIND,
IE LOOKING TOWARDS THE INTERACTION POINT
* IN TERMS OF MECHANICAL NUMBERING
* ALL DEES ARE IDENTICAL
* ALL COMPLETE SUPERCRYSTALS ARE IDENTICAL
(independent of the orientation of the internal HV board)
(numbering inside partial supercrystals is more complicated...)
* WITHIN A SUPERCRYSTAL, THE NUMBERING GIVEN HERE IS THAT OF THE
***INSERT*** INTO THE ALVEOLE
* THE DEFINITIVE EE GEOMETRY IS AT:

2) CRYSTALS WITHIN A SUPERCRYSTAL:
The numbering given here is that of the INSERT into the alveole.
ALL supercrystals (including partial ones) are arranged with the
fully-right-angled corner of the crystals closest to the beampipe
(marked with * below, where the supercrystals are oriented for mounting
on the 'top right' quadrant of an endcap)
Note that the numbering below is INDEPENDENT of whether the HV boards
inside run vertical or horizontal (in complete supercrystals).
NB I bet we trip up over this one, some fine day.
(Sometime in Spring 2002, the RAL mob agreed that, WHEN MOUNTED ON THE DEE,
all the HV boards in complete supercrystals will run in the same
orientation to match with all backplate slots running in the same
orientation (vertically) as one another, creating an apparent mirror
symmetry about the horizontal plane.)
COMPLETE: 5 4 3 2 1
10 9 8 7 6
15 14 13 12 11
20 19 18 17 16
*25 24 23 22 21
**
(552 such supercrystals)
2x5: 20 19 18 17 16 and 5 4
*25 24 23 22 21 10 9
** 15 14
20 19
*25 24
**
(24 supercrystals of each, at outer radii)
[4x {C10M,F9M,G8M, [4x {H7M,I6M,J3M,
J3,I6,H7}] G8,F9,C10}]
4x5: 5 4 3 2 1 and 4 3 2 1
10 9 8 7 6 9 8 7 6
15 14 13 12 11 14 13 12 11
*20 19 18 17 16 19 18 17 16
** *24 23 22 21
**
(8 supercrystals of each, at inner radii)
[4x {A3M, C1}] [4x {C1M, A3}]
3+2+1: 3 2 1
*7 6
** 11
(8 such supercrystals, at inner radii)
[4x {B2M, B2}]
Thus the fully-right-angled corner closest to the beampipe is:
#25 for complete supercrystals
#25 for 2x5 supercrystals
#20 or #24 for 4x5 supercrystals
#7 for 3+2+1 supercrystals

Feedback on any errors will be much appreciated.
However, given the high probability that I will have made some,
a prize will only be given to the BEST feedback...
.... presently Justin.
