In all likelihood, we’ll go with a resistive measurement, (to detect the superconducting state or lack thereof), using a small lead wire. The following setup is from an Alfred Leitner video. We’ll use something even simpler, probably just a lead wire with a four point probe attached. By the way, if you're new to the game, scroll to the bottom for background information. We could sputter a line of lead onto a glass slide, but I don’t see the benefit yet. Working on finding out what it is. Check this out later in the day per shaping samples: https://plus.google.com/116395125136223897621/posts/9c7dFfZ7ijT I’m performing the check on the resistance of the primary coil as its cooled by liquid nitrogen. The idea is that yesterday’s increase in output ignal with the superconductor ooled may have noly been do to the primary pulling more current as its resistance ramped down. Here are a few pictures of the assembly being taken apart for the present...
