Nb-Gun doesn't ignite immediatly (~86µm of material already sputtered)

Copper parts for Bluefors dc-wiring:
only very slow cooldown with all copper parts installed
remove copper parts again: are the cooldowns faster again?
Which kind of copper was used? (Standard,OF,...?)
How were the copper parts treated?
Copper parts should not be cleaned with hydrochloric acid (Salzsäure) (creats chorides/cools down very slowly). Use nitric acid (Salpetersäure) instead.
The improvised dc-wiring can be uninstalled.
Trash containers for clean up are now available. Everyone should take a look through the labs and their offices for stuff that should/could be thrown away.
