October 1997: Progress Report
The leak testing of the east tube has been finished. Five leaks have been detected. After sealing them the vacuum meets the requirements.
A small leak at a flange now determines the pressure (p(N2) ~ 5•10-9 Torr in the middle of the tube). This will be mended soon.
The residual gas is dominated mainly by water. The tube will be encapsulated by rockwool in order to make it possible to heat it up.
