ROSIER Ph. 26-11-03
End cap – TPC - LC Arrangements of detectors on the active area of the end cap (1/2)Squares, rectangles, lozenge of 300/350 mm or 400 mm size
Annotations: F is the type number of frames / P is for the PADS board

F1 – P1
F2 – P2
F2 – P3
F1 – P4
F3 – P5
F2 – P6
F2 – P7
F4 – P8
F2 – P9
F5 – P10
F6 – P11
F7 – P12
F8 – P13
F9 – P14
F10 – P15
These arrangements need too much different sorts of frames and PADS boards, even if the
right drawing is the simplest
These are the same by symmetry
Lozenge arrangement
Mixture of squares and rectangles

End cap – TPC - LC Arrangements of detectors on the active area of the end cap (2/2)Trapezoidal shapes assembled in iris shape
Annotations: Px is the type number of PADS boards or frames
Page 2
By rotation of 15° around the axe, these frames are the same
P1
12 sectors (30° each) as super modules are defined
On each, 7 modules are fixedThe sizes of detectors are varying from 180 to 420 mm
P2 P3 P4
P2P3
P4
These arrangement seems to be the best as only 4 different PADS are necessary

Deformation limit acceptability to define
Here is 20 µm / mbar of pressure
Carbon wheel with frames 20x100 mmDetector 1 made
of 8 mm of epoxy or sandwich
Frame of the super module made of 10 mm epoxy reinforced with 15x40 mm carbon bar
Complete wheel with 12 super
modules
ROSIER Ph. 26-11-03
End cap – TPC - LC Principle for the 4 types of Pads plane
Page 4
Questions:-Do we let 5 mm of dead area on the detector, because then the pads plane is more reduced ?-Are the pads aligned ? From where ? How is managed the radius parameter ?-Connectors density is a crucial point as it drills a lot the detector (and also perimeter problem showed in next slide)
Pads 6 x 2 mm
515000 pads on 12 super modules
approx.(correspond to one
end plate)
Pads plane type 4Pads plane type 3
Pads plane type 2Pads plane type 1
Shape of the connectors 0.8 mm pitch 100 channels each (85x6)
2 pads rows deleted due to the
dead zone

End cap – TPC - LC Principle of the boundaries (electronics on the pads plane )Fixing and sealing of the detectors
Page 5
Electronic board
Epoxy or sandwich detector
Pads plane
Frame of the super moduleEpoxy 10x16 + carbon 15x40
Stud bolts
The pads can go to the boundary but not the electronic boards
Some radiation lengths:
1) Pads + Epoxy detector + Epoxy/carbon Frame = 6.4 %
2) Pads + Sandwich Carbon/Foam 9 mm +Epoxy/Carbon frame = 2.6 %
(Without electronics)
Stiffeners of the super modulecarbon 15x40
