Subject: new chamber almost ready 

the new chamber is almost ready. I've attached three of four heaters, the fourth one has a fabrication error and has to be replaced. The chamber is currently pumped using the old varian ion pump. Current is already down to 100uA and one can watch it further decreasing. So my guess is that it will be clean beginning next week. I turned on two of the heaters to "bake" it a little bit. I baked the ion pump this afternoon while pumping with the turbo at 250C. The new insulated feet are ready and fit now to the chamber. Next task will be cutting the remaining holes into the foam and putting the temp sensors on the chamber.

Here a picture of the current status:
