Early Kesselring Cold Cathode Tube (1898-1910) |
|
|
An early and simple design from this small manufacturer located in
Chicago. The small mass of the target (anticathode) made this tube
susceptible to overheating and unsuitable for prolonged use. As is true of
most early designs, the anode (on right) is opposite the cathode while the
anticathode comes in at an angle.
