Abstract :
A convenient definition of the multipole coefficients of the accelerating field produced by any resonator is given: the monopole term gives the transit time factor, the dipole gives a beam deflection, and the quadrupole perturbs the beam focusing; a notable relation holds for a quarter wave resonator. Improving both the spatial resolution and the sensitivity of the bead technique makes it possible to determine these coefficients reliably. Electronics stability is discussed.<>
