Point-charge wakefield calculations from finite length bunch wake potentials

Point-charge wakefield calculations from finite length bunch wake potentials

We present a new method to accurately calculate point-charge geometric wakefields and/or short-bunch wake potentials from wake potentials due to a much longer bunch, typically obtained with a time-domain electromagnetic (EM) field solver. By allowing a long bunch in the EM solver, this method can si...
