Abstract :
Although the linear theory of stable and unstable synchrotron oscillations has long been understood, there is no such satisfactory description of the large amplitude highly non-linear synchrotron motion. With an appropriate tuning of RF cavity impedance, large amplitude, low frequency, self-sustained relaxation oscillations of this synchrotron motion can be observed. This paper presents experimental data and computer simulations that give insights into the details of the mechanism involved
