That (cathode decay) is indeed a large problem. This sounds nice.
The Helmholtz institute is known for doing research that has direct practical relevance

Their funding is only partially from the government, the rest they have to get companies to pony up - a nice way to force public-private partnership in use-inspired research. It has been demonstrably successful.
