... approximately¹

The well-known integral formula assuming flat beams and nonrelativstic transverse motion agrees on a 10 % level with detailed Monte Carlo simulations [8].

... TRELMA²

The Touschek relevant effective lattice momentum acceptance is the MA value, where the RF alone (i.e. infinite lattice MA), set to the corresponding voltage, and the lattice alone (i.e. infinite RF MA) give equal Touschek lifetimes (normalized to bunchlength) [12]
