Abstract
The paper discusses the method and principle of bunch length measured by HP54121T 20 GHz digital sampling oscilloscope in Hefei Light Source (HLS) ring. The measurement results of the bunch length and the energy spread are given. The r.m.s. bunch length is about 3.8-10.33 cm. A new theory on the bunch lengthening is used to explain the experimental results. It is proved that the beam-cavity interaction is the most important factor to the multi-bunch lengthening of HLS
