TTCS Evaporator Production Status B. Verlaat & M. Van Overbeek NIKHEF, 14 October 2005

Evaporator is split with hydraulic connectors Inner ring Outer ring Intermediate Connectors In & Outlet Connectors

July 2005: 2 Inner rings are produced!

Inner ring under production Bending tool details Soldering set-up

Inner ring production results Copper block details Complete inner ring

1) Bolt analysis was made by ISAtec and A.Alvino. ==> We need better quality bolts for some cases: One junction (tracker feet  tracker) deserves more attention and will be discussed on Wednesday splinter meeting. 2) Tracker fastener list and back off prevention method: Submitted to Jacobs. Update needed for structural fasteners. Back-off prevention clear - Two cases: i) Contained small fasteners : Vibratite ii) Other fasteners: Mylar patch or self locking insert 3) Fracture of composites: Memo submitted to Jacobs. 4) Material list: Delivered to Jacobs Some issues: - Some Al alloy plates to be surface treated in-situ - A few components are prone to stress corrosion Safety issues

Dry assembly of shells-planes was made before installation of ladders on planes. …it continues with the new conical flange and the external planes… Tracker assembly at Uni-GE

Dry assembly continues: - Star tracker lower support to upper conical flange. - P1 to top conical flange - P5 to bottom conical flange. - Spl brackets for evaporators

Dry assembly continues: -Star tracker lower support to upper conical flange. -Two pieces of the camera support to upper plane and upper flange

Assembly of the inner tracker at UniGe Proposed set-up for storage & insertion into the magnet. The various lengths of the cables were calculated. Cables are in UniGe Cables must be installed before the supporting shells. Extra length must be attached to temporary supports.

Tracker assembly at Uni-GE Modifications can start: - Remove / reposition telescopic supports for inner planes. - Build adapters for conical flanges - Define plane transfer method ==> By hand ? ==> With a lifter ? The ETHZ Frankenstein machine has been moved to UniGe

Assembly schedule Inner Tracker assembly can start as soon as : - The three inner planes are ready for assembly  ~End of November Delayed because of a missing ladder - The modifications to Conical flanges / Shell are made (if needed) - The Star Tracker lower supports are bonded to the top conical flange - The fasteners are available Assembly sequence - Transfer the 3 inner planes into the « Frankenstein » in order P2, P3 and P4 - Transfer the conical flanges into the « Frankenstein » - Position planes and connect thermal connectors - Mount cable support structure - Mount and connect cables on ladders of three external rows +Y and -Y - Mount the two 100° shell sectors - Mount and connect all other cables - Mount the two 80° shell sectors Inner Tracker assembly ==> Duration ~2.5 months ~End February2006 if assy starts early December

P5 completed with ladders  ~Mid February 2006 P1 completed with ladders  ~End of March 2006 (Test are not accounted for ) Still a lot of things to finalize / to do for the assembly of the Inner Tracker: - Procure fasteners which need to be replaced - Shopping list for next TIM - Light tightness at exit of conical flange / around the feets - Mesh on light traps - Bond Star tracker lower support - Cable clamps - Structure to support cables - Container for Inner Tracker. - Etc...

Further assembly steps / parts needed - Re-do some bracketry for evaporators in two parts - Mount outer evaporator rings to P1 and P5 - Modify outer plane containers to be compatible with evaporators For integration - Inner Tracker handling gear - Installation jig for Inner evaporator (design A. Alvino) - Cable « paddle » and clamps on Vacuum case (design A. Alvino) - Cable balcony for Tracker crates. Miscellaneous - Prototype condenser - Parts for heat exchanger
