  Since 2016 DESY has been pursuing R&D towards upgrading its PETRA synchrotron light source to a fourth-generation machine, PETRA IV, which is expected to start operation in 2027. The conceptual design of a 6 GeV seven-bend-achromat-based lattice with an approx. 10pm emittance along with critically important technical systems has been completed. We will present the status of the project, the expected parameter space of the facility, and lattice design and beam dynamics issues for the main ring.

  As the machine with the smallest emittance among the planned fourth-generation hard x-ray synchrotron light sources, PETRA IV will have very demanding requirements on magnet alignment and stability. Several developments to address mechanical and beam-based stabilization have been started in connection to that. Here we summarize the alignment and field error tollerances resulting from startup and commissioning simulations of the main ring. Novel high level control tools will be required to assure smooth operation of the machine; progress in their development and beam test results at PETRA III will be reported.

  At DESY the Synchrotron Light Source PETRA III offers scientists outstanding opportunities for experiments with hard X-rays of exceptionally high brilliance since 2009. This paper describes the operational schedule, the operational statistics and the most important beam studies done at PETRA III in 2018.

  PETRA IV project is to upgrade PETRA III to a synchrotron radiation source with an ultra-low emittance. Due to the small dynamic aperture of the PETRA IV storage ring, a horizontal on-axis injection is prepared. In this paper, the preliminary study of the injection scheme is described. To meet the requirements of the on-axis injection, a plan of a new injector complex, including the Gun, the LINAC and the accumulator is shown in this paper. Several options are discussed in this paper, too.
