The lifetime of electron beam is an important parameter, which is directly relative to the operation of HLS. In this paper, the influence of the RF cavity voltage, the coupling factor, and the bunch length on the HLS electron lifetime is studied. It shows that the electron beam vacuum lifetime is comparable to the Touscheck lifetime in HLS. With the Beam Loss Monitor system, the relative change of the beam lifetime is measured, due to the change of the Touscheck lifetime. To increase the coupling factor, the vertical emmitance of beam is increased, and the beam lifetime is improved effectively. The operation of HLS is ensured.
