Die Kathodenstrahlröhre

von

Manfred von Ardenne

This book once issued in 1933 has been copied integrally

Why copying such an out of date book?

Because, in my perception, it is worth it

ad it shows you unique photos of the early days of cathode-ray tubes

Some of which are really nice.

Two examples:

An example of explanation of the so-called Wehnelt-cylinder application

This latter Wehnelt-cylinder were regularly used in Manfred von Ardenne's early cathode-ray tubes

In my perception intriguing photos
