	A new beam diagnostics method to reconstruct the full 5-dimensional phase space (x, x’, y, y’, t) of bunches has recently been proposed. This method combines a quadrupole-based transverse phase-space tomography with the variable streaking angle of a polarizable X-band transverse deflecting structure (PolariX TDS). Two of these novel structures have recently been installed at the ARES beamline at DESY, which is a linear accelerator dedicated to accelerator research and development, including advanced diagnostics methods and novel accelerating techniques. In this paper, realistic simulation studies in preparation for planned experimental measurements are presented using the beamline setup at ARES. The reconstruction quality of the method for three beam distributions is studied and discussed, and it is shown how this method will allow the visualization of detailed features in the phase-space distribution.

THPOJO01	The ARES Linac at DESY	691

	The generation and acceleration of ultra-short, high quality electron beams has attracted more and more interest in accelerator science. Electron bunches with these properties are necessary to operate and test novel diagnostics and advanced high gradient accelerating schemes. Furthermore, several medical and industrial applications require high-brightness electron beams. The dedicated R&D linac ARES at DESY (Deutsches Elektronen-Synchrotron) is now fully operational and able to produce these electron beams at the nominal energy of 155 MeV and deliver it to users. This paper gives an overview of the ARES linac and summarizes the beam parameter measurements. The possibilities for user operation will be described in detail.
