In the aim of detecting or classifying the resonant and trapped dipole modes of TESLA cavities and in order to measure their quality factors, two di erent beam experiments have been already proposed 1, 2 . Presently, the latter cannot be carried out since both require a beam the characteristics of which are the ones of the future TTF injector, Injector II 8 nC bunches, repetition frequency of 1 MHz. The aim of this paper is then to introduce the idea of a new beam experiment consisting in
