ADENIUM — A demonstrator for a next-generation beam telescope at DESY

Abstract

Abstract High-resolution beam telescopes for charged particle tracking are one of the most important and equally demanding infrastructure items at test beam facilities. The main purpose of beam telescopes is to provide precise reference track information of beam particles to measure the performance of a device under test (DUT). In this report the development of the ADENIUM beam telescope (ALPIDE sensor based DESY Next test beam  Instrument) as a demonstrator and prototype for a next-generation beam telescope is presented. The ADENIUM beam telescope features up to six pixelated reference planes framed by plastic scintillators for triggering. ADENIUM is capable of replacing the currently used EUDET-type beam telescopes without impacting existing DUT implementations due to the integration of the telescope DAQ into EUDAQ2. In this report the concept and design of the ADENIUM telescope as well as its performance are discussed. The telescope's pointing resolution is determined in different configurations. For an optimal setup at a momentum of 5.6 GeV with an ALPIDE as DUT, a resolution better than 3 μm has been extracted. No rate limitations have been observed at the DESY II test beam.
