  Ultimate storage ring (USR) with natural emittance comparable to diffractive limit is becoming a compatible candidate for next generation hard X-ray light source. When FEL technique is employed, it can deliver a high quality beam with very high brightness compared to 3rd generation light sources and transverse coherence which facilitates the power growth. In this paper, we propose a design of a 5GeV USR with emittance at 10pm for both planes. A lattice of nBA type is used and combined function magnet is employed to make a compact storage ring.

  In this report, we present our electron beam measurements with a wall gap monitor (WGM) in ALPHA injection and extraction beam lines. The WGM is first bench mark tested, and then installed in the ALPHA injection line to measure both the macro andμpulse of the injected beam and calibrate the beam current. By scanning the bending magnet before the WGM, and applying a demodulation signal processing scheme, we measured the tomography of the longitudinal phase space of the injected beam. We moved the WGM to extraction beam line and measured the properties of the extracted beam. By comparing the frequency spectrum of injected and extracted beam, we have confirmed the debunching performance of ALPHA.
