“…Electron gun: A 300 kV thermionic gun produces bunches at 650 MHz and delivers up to 10mA average beam current in CW mode [1]. Linac: This consists of three 9-cell 1.3 GHz niobium cavities working at 2 K in two different cryomodules [2,3,4,5]. The injector cryomodule contains one cavity and the second cryomodule contains two.…”

Now 30 MeV stage of the ARIEL (The Advanced Rare Isotope Laboratory) e-Linac is under commissioning which includes an injector cryomodule (ICM) and the first accelerator cryomodule (ACM1). The two ACM1 cavities are driven by a single klystron with vector-sum control and running in CW mode. During the commissioning, the ACM1 cavities gradient and stability were limited by a ponderomotive effect [1-4]. Acoustic noise from the environment including vibration sources from water- and air-cooling systems, cryogenic system and vacuum system have been identified. In this paper, the progress of the microphonics suppression of ACM1 is presented.
