Prometheus Fusion Perfection

Got the first bubble detector today:

Unfortunately without the pumps it’s all dressed up and nowhere to go. These have a shelf life of 90 days, and must be stored in their airtight cigar case:

I had to purchase 3 of these. Each will ship as the last expires, so I’ll have 270 days of coverage.

Also got two IGBTs today:

These can switch 200A 600V.

Marking:

Fuji A50L-0001-0260/A

2MBI200KB-060.

Pretty heavy duty! I expect to use these on the next run with the superconducting magnet to quickly disconnect the power supply from the magnet.
