Abstract
An advanced prototype of a digital pixel calorimeter, EPICAL-2, has been constructed using ALPIDE MAPS sensors. It has been successfully tested with cosmic muons and with test beams at DESY and the CERN SPS. We will report on recent updates of performance results, with good linearity and resolution. Comparisons to detailed MC simulations are made and show good understanding of the technology. The spatial precision of event-by-event measurements of the showers allows unprecedented studies of the shower shape. The detector features two-shower separation capabilities at extremely small distances. We will also discuss the limitations of the currently used sensor technology and perspectives for future development of digital calorimetry.
