WebHillas (1984) extended the CR energy limit argument to sev-eral classes of astrophysical sources. He equated the time to dif-fusively escape across the source radius with the characteristic time for diﬀusive shock acceleration and found the correspond-ing, limiting Larmor radius which he had taken as a measure of the scattering mean free path.
