Module
Dow Corning type foam not used at this location for Agata
Necessary for Aida, as it for example central module is slightly higher than
other two, (due to mechanical tolerance build up) it could reduce the level
of cooling available for the other modules

Boards in
‘correct’
orientation
Boards rotated
clockwise
Boards inverted
I don’t mind the inverted boards, as it doesn’t affect the mechanics, but I
would prefer to avoid the clockwise and anti-clockwise boards

AIDA
There are 3 ways to do
this
1. Make two different detector connection boards, 1 for the vertical
option, and 1 for the lateral options.
2. Make 1 detector connection boards, with 2 sockets for the kapton
cable. Only 1 of which is used.
3. Twist the cables…
