Am LHC haben sie tatsächlich eine Waschmaschine für Platinen.
It’s a professional machine (mainly used in the pharmaceutical industry) designed to clean everything that can be washed with a water-based chemical soap. This type of treatment increases the lifetime of the electronic boards and therefore the LHC's reliability by preventing corrosion problems in the severe radiation and ozone environment of the LHC tunnel in the presence of beams. “We use an alkaline cleaning agent specifically designed for electronics,” explains Sylvain Kaufmann, of the Machine Protection and Electrical Integrity group (TE-MPE-EM). “The cleaning agent removes soldering residuals, contamination particles and manipulation traces like fingerprints.”
