These preliminary observations seem to exclude a Touschek-effect explanation since bunch length was independent (within the experimental accuracy of about 10 %) of transverse beam size. Also apparently excluded is a beam-cavity interaction since with one intense bunch and one weak bunch the intense one is long and the weak short—while theQ of the cavity would seem to preclude this effect. Wall resistivity effects also seem to be excluded because of their smallness.

H. Hereward has pointed out (private communication) that (18) can be interpreted as a reduction in the inductive contribution toE n0, of order (H/πR)2; which is quite a reasonable result, from a simple circuit theory point of view.
