ERL model, in which the accelerating beam (10 mA)
is turned on at 5.1 ms at 7 degrees off crest,
and the decelerating beam is turned on at 10.1 ms,
also at 10 mA, but at 173 degrees out of phase.
The top two plots show the RESULTANT beam amplitude
and phase. Note the resultant beam current is
about 2.44 mA [10mA*(sin7 + sin173)], and its phase
is 90 deg.
Also note the non-zero imaginary part of the generator
current (6-th plot) that starts when the accelerating
enters the cavity off crest, thereby generating an
imaginary component of the beam current.
