Objective

Evaluate the performance of two nested HTS coils (inner: 2m, outer: 3m) in different configurations and compare results to a single 5m coil.

Steps

• Coil Fabrication ✅ 2025-02-18
  • Wind inner coil (2m) on small mandrel Mgn_010 ✅ 2025-02-18
  • Wind outer coil (3m) on large mandrel Mgn_011 ✅ 2025-02-18
  • 3D print hall sensor adapter for large madrel size ✅ 2025-02-18
• Individual Coil Testing
  • Test Coil 1 (Inner, 2m)
  • Test Coil 2 (Outer, 3m)
• Parallel Configuration Testing
  • Power both coils in parallel
  • Measure combined field strength
  • Evaluate efficiency
  • Assess thermal behavior
• Comparison with Single 5m Coil
  • Test 5m coil as benchmark
  • Compare performance: field strength, efficiency, losses, stability
• Analysis & Conclusions
  • Evaluate nested coil benefits vs. single coil
  • Identify optimizations and applications

Remarks

• Coils Mgn_010 too wide to fit inside mandrel for Mgn_011, so remake with outer mandrel to fit. Use 8mm inner mandrel size.
• Make Mgn_012 with narrower inner bore and an outer mandrel, but outer mandrel sadly a bit too large to fit into Mgn_011
