Here instructions how to disconnect the detector support and the elliptical head.

RF Box

The box is made by the method of "Foil hot pressure forming". Research concerning the optimal temperature during forming has been done at Groningen University. A study of the effect of welding of the foil was made for the innerside and outerside vs. neutral, moreover a microanalysis of the welding process has been performed.
The effect of  NEG coating on the RF Box has been measured in 2005.
Drawings of the box can be found here.

Milling

An effort to create a foil by milling instead of by deformation is pursued. Here some pictures of the first result:
