Superconducting coils for damage studies

This page was created as source of information about small racetrack superconducting coils created for damage study foreseen in October 2022.

1. Measuring the gap size

The gap, where wire will be placed was designed to have a width of 4.9 mm (0.1 mm). To check this, twelve different pieces were measured with micrometer (precision 0.0001 mm).

It could be seen from the attached table that, the actual size of the gap is in fact more than 0.02 mm bigger.

2. Labeling the coils

To distinguish between coils, they were labeled with numbers between 0-29. The label is always on side where the winding is started. Following table specifies the coils.
