are the - - ANSWER- Laminae

- ANSWER-

Where do the electrons that travel across the tube come from? -
ANSWER- Thermionic Emission

How are the electrons accelerated across the tube? - ANSWER- High
Voltage

In what direction do electrons flow across the tube? - ANSWER-
Cathode to Anode (Spinning)

How are electrons focused in the tube? - ANSWER- With focusing Cups

What happens when electrons are decelerated? - ANSWER- They give
off Photons

,How are electrons slowed down in the tube prior to emission of
photons? - ANSWER- The curve a tungsten nucleus. Bremsstrahlung
