German "Super Iconoscope" (1936)
This camera tube was used to televise the
1936 Berlin Olympic Games. It was developed by Dr. Heimann of
the Post Office Ministry in Berlin. The cathode had a life of
only a few hours. Every night after use, the electron gun (in
diagonal tube) was removed and a new one inserted. The tube was
then evacuated for use the next day.
