Description
Ultra-low emittance is one of the primary directions for the development of synchrotron radiation facilities. To manage coupled-bunch instabilities and achieve beam lifetime expectations, higher-harmonic cavities have become a common requirement for diffraction-limited storage rings. bimodal cavities are considered a multifunctional and compact accelerating structure capable of integrating the functions of a fundamental RF cavity and a higher-harmonic cavity. To meet the demands of low-energy storage ring light sources development, we propose an active bimodal RF cavity operating at low frequencies of 166 MHz and 498 MHz, and coaxial couplers is designed.
