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.
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.
