Situation du projet collier pour préparation du 'Work Package' en Iran prepared by : M. Oriunno & D. Druzhkin
Shielding:Final optimization: April 03 Respect max torque on RS hinges Equalize load on HF jacks “CASTOR” T2 thin pipe 13-18 m good for 1034 pp with no CASTOR (vac to be checked)
Constraints on the max. loads on the 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 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 Va Vb
Final optimization: April 03 Neutron (E>100keV) flux maps (Mika Huhtinen) pp 1034 cm-2 s-1 OK for pp < ~ 1033 cm2s-1 -as good as before, but with thin beampipe. -better balanced along z. (no particular weak-point)
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 MODULAR SYSTEM
The evolution Once upon in a time a shielding……. …today a CMS region with an high density of detectors, monitors and services ! Collar Table T2 GEM CASTOR
