    Prototype Lead Tungstate Calorimeter Test for TPEX

    Full text link
    Tests of a prototype lead tungstate calorimeter were made over two weeks at the end of September, 2019, at the DESY II Test Beam Facility in Hamburg, Germany. The purpose of these tests was to gain experience with the construction, operation, and performance of a simple lead tungstate calorimeter, and also to compare a traditional triggered readout scheme with a streaming readout approach. These tests are important for the proposed Two-Photon Exchange experiment at the DESY test beam facility and for work towards a future electromagnetic calorimeter that could be used in an Electron-Ion Collider detector. Details on all aspects of the test, the subsequent analysis, and the results are presented.Comment: 7 pages, 15 figure
