In the A2 experiment at the Mainz microtron (MAMI) electron accelerator, the production of nucleon resonances and light mesons off protons and nuclei using energy-tagged bremsstrahlung photons is studied. Decay products are measured with two electromagnetic calorimeters: Crystal Ball (CB), whose 672 NaI crystals cover almost the entire solid angle, and TAPS, which consists of 366 BaF2 and 72 PbWO 4 crystals in the forward direction. Here, we report on the current performance and status of both detectors after 10 years of operation in Mainz. In addition, we present the new CB high-voltage system, a new fast readout scheme for TAPS, and the planned upgrade of the CB data-acquisition system.
