LINAC parameters used in calculations
1) pulse width 50 ps
2) pulse current 50 A
3) repetition rate 300 Hz
4) energy 44 MeV
Number of electrons/sec on radiator
Number of photons/sec out of radiator
Alex factor is 6.85 %
Pair production rate
out of Al converter
(by varying width we can vary the yield)
through 1 m of air
