    Construction and Testing of Novel Designs of Resistive Plate Chambers
    (Institute of Electrical and Electronics Engineers Inc., 2018) Bilki B.; Onel Y.; Repond J.; Xia L.
    Resistive Plate Chambers (RPCs) exhibit a significant loss of efficiency for the detection of particles, when subjected to high particle fluxes. This rate limitation is related to the usually high resistivity of the resistive plates used in their construction. Here we report on the measurements of the performance of various different glass RPC designs featuring a different total resistance of the resistive plates.In parallel, a novel design of RPC, using only a single resistive plate, was developed and tested. Based on this design, large size prototype chambers were constructed and were tested with cosmic rays and in particle beams. The tests confirmed the viability of this new approach. © 2018 IEEE.

    Digital Hadron Calorimetry
    (Institute of Electrical and Electronics Engineers Inc., 2021) Bilki B.; Guler Y.; Onel Y.; Repond J.; Xia L.; On behalf of the CALICE Collaboration
    Calorimeters that can fully exploit the power of Particle Flow Algorithms, which attempt to measure each particle in a hadronic jet individually, emphasize spatial granularity over single particle energy resolution. In this context, the CALICE collaboration developed the Digital Hadron Calorimeter. The Digital Hadron Calorimeter uses Resistive Plate Chambers as active media and is read out with 1 x 1 cm2 pads and digital (1-bit) resolution. The Digital Hadron Calorimeter went through a broad beam test program over several years to yield a unique dataset of electromagnetic and hadronic interactions with unprecedented spatial resolution. In addition to conventional calorimetry, the Digital Hadron Calorimeter offers detailed measurements of event shapes, rigorous tests of simulation models and various analytical tools to improve calorimetric performance. Here we report on the results from the analysis of DHCAL data and comparisons with the Monte Carlo simulations across various test campaigns. © 2021 IEEE.

    Hadron Calorimetry With Extremely Fine Spatial Segmentation
    (Institute of Electrical and Electronics Engineers Inc., 2022) Bilki B.; Onel Y.; Repond J.; Xia L.
    Particle Flow Algorithms attempt to measure each particle in a hadronic jet individually, where the major task for the hadron calorimeters is to measure the neutral hadrons. The calorimeters that can fully exploit the power of Particle Flow Algorithms emphasize spatial granularity over single particle energy resolution. In this context, the CALICE collaboration developed the Digital Hadron Calorimeter (DHCAL). The active media of the DHCAL are the Resistive Plate Chambers which are read out with 1 x 1 cm2 pads with 1-bit (digital) resolution. The DHCAL went through a broad beam test program over several years to yield a unique dataset of electromagnetic and hadronic interactions with unprecedented spatial resolution. In addition to conventional calorimetry, the DHCAL offers detailed measurements of event shapes, rigorous tests of simulation models and various analytical tools to improve calorimetric performance. The simulation of the DHCAL response is also a particularly challenging task. Here we report on the results from the analysis of DHCAL data and recent advances on the simulations, and discuss the near future plans including further tests of the hadronic interaction models. © 2022 IEEE.
