The recent demonstration of sub-GV/m accelerating fields at X-band frequencies* offers an alternative pathway to designing a compact light source. The high fields were enabled by powering the accelerating structures using short (<10 ns) X-band RF pulses produced via a two-beam-accelerator (TBA) scheme. In this contribution, we present a conceptual design to scale the concept to a ~0.5 GeV accelerator. We present the optimization of the photoinjector and preliminary beam-dynamics modeling of the accelerator. Finally, we will discuss ongoing and planned experiments toward developing an integrated proof-of-principle experiment at Argonne National Laboratory combining the 0.5 GeV linac with a free-electron laser. * W.H. Tan, et al. DOI: 10.1103/PhysRevAccelBeams.25.083402 (2022).

	A high-average-current VHF electron gun operating in the CW mode is under construction at Shanghai Advanced Research Institute, which is the key component of a kW-power-order free electron laser facility. The average current and the frequency of this electron gun is 1-10 mA and 217 MHz, respectively. To validate the performance of this instrument, a test platform has been designed. The R&D of its vacuum and diagnostics are presented in this work.
