Abstract

The authors of the original article, Valdivia Garcia and Zimmermann (2021), state that they "derive analytical formulae for the equilibrium beam parameters, considering the varying electromagnetic field during the collision". However, to calculate the bending radius in the field of the counter-propagating bunch, they employed an approximation that is completely unjustified. Consequently, a significant portion of the formulae derived in the article bears a very tenuous relationship to reality. For practical purposes, we propose a different solution -- one that is far simpler and more accurate.
