Toshiba Diffraction Tube
Ref. E7
The Toshiba oil-immersed diffraction tube has metal shielding on the middle part of the tube, with a “W” and a “T” etchings which mean the target is Tungsten (Wolfram in German).
It has a heavy ten-layered metal heat-sink and two symmetrically-opposite X-ray ports with Beryllium filters.
Other specifications remain unavailable.
