Canada

This tube used in Grimsby, Ontario.

Function

To generate x-rays by passing high voltage current through a coolidge tube.

Technical

The ring type attachment to the anti-cathode is inspired from an old tube design "The Penetrator Tube" illustrated in Practical Radiography, 1898, (A.W. Isenthal and H. Snowden Ward, p.63, Fig.32). Ring type attachments to the anti-cathode are equally seen in a catalog of early tubes by C.H.F.Müller (tubes No. 8, 9 and 14 in the illustration below from Medica Mundi, p.18, vol 35, 1990). Presumably this attachment improves the efficiency of the electron beam hitting the target. 1
