Outline 4/23/2015MQXFS Mechanical Interfaces2 Magnet Packaging envelope & interfaces Pizza box connections Wiring & Connectors Status

MQXFS Assembly 4/23/2015MQXFS Mechanical Interfaces3

MQXFS Assembly Length Requirements 4/23/2015MQXFS Mechanical Interfaces mm 180 mm 145 mm 355 mm* 428 mm * Extended lead length due to CERN coils being produced with 375 mm long copper stabilizers instead of 2 nd NbTi cable

4/23/2015MQXFS Mechanical Interfaces5 MQXFS Assembly Diameter requirements 614 mm Dia. shell 647 mm Guide Plate* CERN-style shell SG connector on OD of shell, approximately ~15 mm proud in one location Connector can be oriented to line up with one of the 647 mm diameter lobes

*LQ Test Configuration 4/23/2015MQXFS Mechanical Interfaces6 Tri-lobed 647 mm dia. Guide Plate was used in the LQ tests

4/23/2015MQXFS Mechanical Interfaces7 MQXFS Assembly Support Interface Typical ¾-10 tapped 4-hole pattern support interface HQ-style support ring and connector skirts

4/23/2015MQXFS Mechanical Interfaces8 MQXFS Connection Box Design Splices (and CLIQ leads) will be made in two layers Current leads CLIQ leads (max. 3) Full-size cables shown

MQXFS Wire Routing 4/23/2015MQXFS Mechanical Interfaces9 All IL wires will pass thru wire guides underneath the axial endplates

4/23/2015MQXFS Mechanical Interfaces10 MQXFS Wire Routing All wires will terminate in Hypertronics connectors on LE of magnet Wires from RE will be routed through wire guides in 1 or 2 cooling holes

Status 4/23/2015MQXFS Mechanical Interfaces11 Pizza box connection box is currently being detailed – RFQs to be issued early May – Fabrications to be complete mid-June Wiring & Connectors – Support rings & connector skirts need to be detailed – IL Wire guides design is complete Real Coils are expected to arrive mid-May (CERN and BNL)
