A. Range of achievable spot sizes at target of a Pierce Electron gun running between 100W to 6KW 150KV ? ( given cathode is 1.6m from target max deflection 7 degrees )
B. Possible pit falls of running an SEM at 100W in four-source photometric stereo Ruderford back scatter mode ? ( typical SEM power is 0.1W )
C. Target metal surface temperature measurement would be a big advantage, Do you know of a electron bombardment based remote temperature measurement approach?
