1. Status of SF Model Dipole Contract with TAMU
Tim Michalski, Probir Ghoshal

2. Contract Deliverables
Complete development of the FRP (Fiber Reinforced Plastic) Structure for 1.2m Model Dipole
Complete a 125m long section of CICC (cable in conduit conductor), capable of winding the 1.2m Model Dipole
ORIGINAL – complete winding of CICC onto FRP Structure; measure position of windings
REVISED – wind 10m (approximately 3 windings) of mock CICC onto FRP Structure; measure position
Deliverable was revised for both cost and schedule reasons
Final Report on the Contract Performance

3. FRP Structure - COMPLETE
The FRP Structure has been delivered to TAMU
Original Delivery Date was February, 2018
Actual Delivery Date was May 30, 2018
Other machined parts for end groups were fabricated at TAMU machine shop and by local machine shop – all parts are completed

4. FRP Structure – Accuracy and Impact on Multipoles
TAMU has calculated projected multipoles based on accuracy of fabricating the FRP Structure
The position of CICC is controlled by the machined slots in the body of the FRP Structure

5. 125m CICC Production
ATC procured a stranding machine to fabricate CICC
Stranding machine is installed, debugged, and operating
Prototype run with bronze wire is complete
Will transition to SC Strand for running 125m length
Can run up to 3m per minute

6. Winding CICC onto FRP Structure
This has already been demonstrated via the mockup winding (last year)
Bending tools are being modified to accommodate stiffer CICC (vs copper tubing)
Spring back requires 12° overbend and tooling bend radius of 1.83” to get final 2” bend radius

7. Summary FRP Structure fabrication is complete!
Measurement of FRP Structure should yield well functioning magnet
Stranding machine is up and functioning with good quality prototype run
NEXT STEPS:
Validate draw die and caterpillar to attain CICC final diameter
Setup stranding machine with perforated center tube and SC strand material
Fabricate a 10m length of CICC for winding 3 turns
Fabricate a 125m length of CICC for full model dipole winding
Wind 3 turns onto FRP Structure (to be QA’d at JLAB)
Final Report
OPPORTUNITY(?):
See if there are enough funds available to perform full winding onto FRP Structure
