The Story So Far
Used HTS tape to make a punch
Selected radius of solenoid based on
measurements
Designed and built apparatus
Wrapped HTS tape
Attempted to Connect Leads
Apparatus Dimensions
3” high with ¾” thick base
5” O.D. with ½” thick walls
< 1 ¼” Inner diameter to slide PVC over
15/16” Through hole for punch

HTS Tape Wrapping
For a 2.5” diameter
1.5 m tape
2” length
60 m tape should
be 80”
Our solenoid is 6”
tall -> 13 layers

Tests
Inner magnetic field with Magnetometer
Critical Current
Self-Field limitations (voltmeter and
Magnetometer)
Force
Compare to results from copper solenoid
Immediate Goals
Use propane torch to solder power leads
Experiment with aspect ratio
Insulate with Kapton tape
Heat conduction calculations for Helium
Build final sized apparatus
Connecting Power Leads
Final Design
Flat disk of Al from
original ingot
Two large diameter
tubes attached to
bottom disk
