Xmpl2d23, 23rd 'example' data file for CPO2D

Conventional plate deflector


The following data were obtained when the memory and speed of PC's was much more limited than at present, so the available number of segments was small and the requested inaccuracies were fairly high to give a quick demonstration.

 

Two plates of length 2 are separated by the distance d = 1.

 

A beam of 7 rays that initially converge to the point (0,12) is set up.

After deflection the rays converge to the point (0.9992,11.48). The deflection voltage of 0.0274 is chosen to give a deflection of approximately d. The spread in the x direction is approximately 0.00028.
