Morgagni -100kV T12 - 120kV Tf20 - 200kV |
Acceleration voltage determines the speed and therefore the wavelength of the electrons generated.
The electrons generated by the Tf20 are travelling at about 208,440,000 meters per sec or 69.5% of the speed of light. This gives them a wavelength of 0.002 nm compare that to visible light which has a wavelength of 400-800 nm.
