DUO 008 B

The eduards pump started to make vary scary sounds.
Got a really cool (ehh, getting quite hot actually) second hand Pfeiffer & Balzers DUO 008 B.
Still don't have 5E-8 mbar, which is what I need, mass spectro meter shows about 60% H2O, and some junk at higher masses (35...45, probably hydrocarbon), N2 was at 1E-8, so no leaks.
Conclusion: I should do better cleaning, and bake out.
In the rack you can see the second hand water pump (from a central heating system) and the car radiator (Toyota), seems a bit of an overkill for cooling the turbo pump, but the cooling system is going to pump water though a heat exchanger for the oil cooling of the electromagnets.
It can handle about 2kW if the fan is turned on.
