Shielding:Final optimization: April 03
thin pipe 13-18 m good for 1034 pp with no CASTOR (vac to be checked)
“CASTOR”
T2
Respect max torque on RS hingesEqualize load on HF jacks

HF Weight Break down (HF EDR):
HF = 215 t
Table = 25 t
Risers = 18 x 3 t
Mini Racks = 0.250 x 4 t
TOTEM Platform = 5 t
Grand Total = 300 t
Va Vb
Collar Weights
Collar 2 x 4395 Kg
Table 1 x 2450 (1 x 4550 with CASTOR) Kg
Platform 1 x 5100 Kg
Grand Total 18440 Kg < 20 tons
Constraints on the max. loads on the jacks

Final optimization: April 03
Neutron (E>100keV) flux maps (Mika Huhtinen)
-as good as before, but withthin beampipe.-better balanced along z. (no particular weak-point)
OK for pp < ~ 1033 cm2s-1
pp 1034 cm-2 s-1

The Conceptual Design
Collar Shielding independent from Vacuum Cahmber/T2/CASTOR/BCMs
Possibility to stage the detectors/services independently
Minimal system : Collar shielding close around the vacuum chamber
Full occupancy system : T2/CASTOR/BCM
