Construction detail: anode line

The anode line is a sandwich construction, as can be seen in the construction drawing.
The inner part is a aluminum pipe 70mm wide (ext.) 5mm wall. The top part is
machined so that the GI46B anode cooler fits in. Some cooling paste is used to
assure good thermal contact. Teflon sheet (0.5mm) is mounted on the inner part,
to form an isolation for the High Voltage (2.2kV) on the anode. The outer part
of the sandwich is made of brass sheet (0.3mm) which is rolled thightly over the
teflon isolation layer. The sheet is soldered with silver-solder-alloy.
