1 M.Oriunno/ D.Druzhkin Situation du projet collier pour préparation du 'Work Package' en Iran prepared by : M. Oriunno & D. Druzhkin

2 M.Oriunno/ D.Druzhkin Shielding:Final optimization: April 03 thin pipe m good for pp with no CASTOR (vac to be checked) “CASTOR” T2 Respect max torque on RS hinges Equalize load on HF jacks

3 M.Oriunno/ D.Druzhkin HF Weight Break down (HF EDR): HF = 215 t Table = 25 t Risers = 18 x 3 t Mini Racks = x 4 t TOTEM Platform = 5 t Grand Total = 300 t Va Vb Collar Weights Collar2 x 4395 Kg Table1 x 2450 (1 x 4550 with CASTOR) Kg Platform1 x 5100 Kg Grand Total18440 Kg < 20 tons Constraints on the max. loads on the jacks

4 M.Oriunno/ D.Druzhkin Final optimization: April 03 Neutron (E>100keV) flux maps (Mika Huhtinen) -as good as before, but with thin beampipe. -better balanced along z. (no particular weak-point) OK for pp < ~ cm 2 s -1 pp cm -2 s -1

5 M.Oriunno/ D.Druzhkin Update of the parameters

6 M.Oriunno/ D.Druzhkin Update of Parameters

7 M.Oriunno/ D.Druzhkin Update of Parameters

8 M.Oriunno/ D.Druzhkin 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

9 M.Oriunno/ D.Druzhkin The evolution T2 GEM CASTOR Table Collar Once upon in a time a shielding ……. …today a CMS region with an high density of detectors, monitors and services !

10 M.Oriunno/ D.Druzhkin Table of Collar with sliding mechanisms Manual mechanism for CASTOR Opening CASTOR cradle

11 M.Oriunno/ D.Druzhkin Table of Collar with CASTOR, BCM2 and the T2 sliding mechanism

12 M.Oriunno/ D.Druzhkin Detailed Drawings

13 M.Oriunno/ D.Druzhkin Detail drawing half collar

14 M.Oriunno/ D.Druzhkin Detailed drawing Collar Table

15 M.Oriunno/ D.Druzhkin Collar table study

16 M.Oriunno/ D.Druzhkin The platform for the collar shielding

17 M.Oriunno/ D.Druzhkin

18 M.Oriunno/ D.Druzhkin Finite Element Analysis Weights Collar2 x 4395 Kg Table1 x 2450 (1 x 4550 with CASTOR) Kg Platform1 x 5100 Kg Grand Total18440 Kg < 20 tons
