LPPFusion team members connected the new tungsten cathode to a steel connector plate in a number of steps First, Ivy Karamitsos rolled indium, a soft metal on top of the microcracks in the tungsten. This provided an alternate path for the current. Then Eric Lerner and Ivy measured the resistance with a micro-ohmmeter, confirming that it was low enough. Next Ivy, Eric and Mark Klepheke rolled indium onto the entire rim of the tungsten and to a groove in the steel plate. When the two pieces were bolted together, the indium squashed together into a low-resistance contact. Again, micro-ohmmeter measurements showed where resistance was still too high and the bolts had to be tightened. In the end, low resistance was secured everywhere.
