Test beam campaigns are an essential part of modern detector R&D to study performance parameters in an environment closest to the final experiment. The DESY II test beam provides EUDET-style pixel telescopes based on MIMOSA-26 sensors for more than 10 years, which provide an unprecedented pointing resolution but no timing information. As the time resolution becomes more and more important, several upgrades are planned to adapt the telescope to the increasing requirements of the next decade. The novel trigger logic unit is used to synchronize several detector systems has opened the path to more flexible setups: First prototype timing planes based on LGADs as well as a fast region-of-interest trigger and timing plane based on an HV-CMOS process are proposed short term upgrades of the facility. A new telescope, based on a thin CMOS sensor is foreseen as a mid-term replacement of the current telescope, which reaches its end of life soon. A long-term upgrade of the telescope is envisioned to be based on a 65nm imaging sensor
The presentation will briefly introduce the facility and sketch the requirements on the telescopes, as well as the current status. The integration of additional timing layers will be discussed in detail and results from test beam campaigns will be shown to highlight the improvements.
