Description
The PANDA experiment at FAIR will in future provide outstanding
data to advance the field of hadron spectroscopy.
One of its essential detector components, the forward endcap
(FWEC) of the electromagnetic calorimeter was recently
tested at the COSY accelerator, equipped with 20% of its
crystals under final operation conditions.
The test beamtimes conducted in August and September 2023 with a
2.74 GeV/c proton beam and a plastic target, collected extensive
data via full waveform readout.
Key achievements included e.g. a stable operation of the FWEC
at -25°C and its first measurement of a $\pi^0$-signal
decaying into two photons, which will also be essential for
calibration of the detector system.
This poster presents the FWEC assembly process, data pre-processing,
and reconstruction using PandaRoot, leading to the observation of
the $\pi^0$ signal.
