I mean if you didn't already know how to solder to Germanium crystals you would have had to spend months experimenting with the material before you could get leads to stick.

Google said (AI result):

  Soldering a lead to a germanium crystal typically involves using a gold-germanium solder alloy (like 88% gold, 12% germanium) due to its compatibility and good bonding properties
Also one of the search results implied etching first could help remove germanium oxide and used a different solder: https://www.researchgate.net/post/How-to-solder-germanium-wa...

Plus you'd need to decide how to get a good thermal connection to set the temperature of the crystal - maybe via one big lead?

Being in the future makes some things simpler?

The little experience I've had with lab physicists showed they needed a good ability to build, debug and maintain their own equipment. You can't always rely on technicians.
