SQXF statusCable R&D

• Target criteria established– Mechanical stability during winding– Stability current Is ≥ 3*Iop

– RRR after cabling > 150– No shear planes in micrograph images

• First iteration completed in 03/2013– Winding tests, cross-section images, extracted strand meas.

• No cable reached all targets• Second iteration has started

– Cabling, winding tests, micrograph images in 04/2013– Extracted strand measurements in 05/2013– Cable parameters for first set of coils by end of 05/2013

• Cable R&D will continue (PIT strand, improved parameters…)

09/04/2013G. Ambrosio and P. Ferracin 3

SQXF statusInsulation R&D

• First ten-stack measurements in 03/12– Either too thin (LARP) or too thick (CERN)

• Thickness optimization in progress• Target 125-150 micron

09/04/2013G. Ambrosio and P. Ferracin 4

SQXF statusCoil design and magnetic design

• First iteration completed• 2D magnetic analysis

– Coil cross-section and yoke design– Magnetic shimming

• 3D magnetic analysis (OPERA and Roxie)– Peak field– 3D Field quality

• 3D CAD model– Coil (turns and blocks)– End spacers (Roxie and BEND)

SQXF statusCoil fabrication tooling

• First iteration of pole and end-shoes design completed

• Design of W&C and R&I started in 03/2013

09/04/2013G. Ambrosio and P. Ferracin 6

SQXF statusSupport structure

• 2D optimization completed– Update of the structure (alignment assembly features)– Alignment key– Dimensions of the components– LHe vessel mechanical analysis– Effect of coil deformation on field quality

• 3D analysis started• 3D CAD modelling in progress• Integration, LHe vessel containment, length

– Two options (CERN, BNL) under study

09/04/2013G. Ambrosio and P. Ferracin 7

SQXF plan and schedule• Update of coil design in 06/2013• Coil parts fabrication/optimization from 06/2013

– To be completed by end of 2013• Coil tooling

– Design completed in 05/2013– Procurement

• Parallel coil fabrication LARP-CERN– CERN: 1 Wind&Curing + 1 React&impreg– LARP: 1 Wind&Curing + 2 React&impreg

– Winding and curing by 10-11/2013• End parts optimization and test of fabrication process

– Reaction and impregnation by 02/2014• Fabrication of full practice coil starts, both at CERN and in the

US, in 03/2014– First long coil wound in 01/15

09/04/2013G. Ambrosio and P. Ferracin 8

SQXF plan and scheduleCoil fabrication

• CERN– Number of coils

• 1 Cu coil• 1 practice + 5 real RRP coils• 1 practice + 5 real PIT coils

– After SQXF01

– Fabrication steps• Winding + curing + reaction +

impregnation– Fabrication time

• ~100 days (5 months) per coil• 1 coil produced every 2 months

• LARP– Number of coils

• 1 practice• 1 mirror + 4 real RRP coils

– Fabrication steps• FNAL: winding + curing• LBNL: reaction + impregnation• BNL: reaction + impregnation

– Fabrication time• ~100 days (5 months) per coil• 1 coil produced every month

09/04/2013G. Ambrosio and P. Ferracin 9

• Sequence: CERN will start with RRP coils– SQXF1 magnet will include the first available four RRP coils produced by the two

“production lines” – With the current plan, either 3 LARP + 1 CERN or 2 LARP + 2 CERN

SQXF plan and schedule

• Support structure – LARP/CERN design

• Identical design for SQXF and LQXF– 2 SQXF structures fabricated and qualified at CERN

• 1 long structure fabricated and assembled by LARP– From conceptual design to assembly and qualification

• From beginning of 2013 to end of 2014• Tests

– First coil test (mirror) in 12/14• Feedback for LQXF coil fabrication (first winding in 01/15)

– First magnet test (SQXF1) in 04/15• First assembly of LQXF in 10/15

– Feed-backs from SQXF to LQXF on loading

– Then SQXF1b (RRP), SQXF2 (PIT), SQXF2b (PIT)

LQXF Goals

• GOALS:– LQXF1/2: Demonstrate main features of MQXF cold

masses• Aperture, length, main requirements

– LQXF3: MQXF prototype

• DESIGN CRITERIA:– Coils, tooling design, and structure developed with SQXF:

• Same coil parts, same tooling design, same process, …– Prototype features to be defined by Design Report (2015)

09/04/2013G. Ambrosio and P. Ferracin 12

PLANS

• LARP effort for demonstrating readiness for construction project (US DOE criteria)

• Fabrication plan is based on LQ and LHQ plans – Strand procurement: BNL and LBNL– Cabling: LBNL– Cable insulation: NEWT (different from LQ)– Coil W&C: FNAL– Coil R&I: BNL and FNAL– Structure & assembly: LBNL– Test: FNAL and/or BNL
