Description
KOALA will be an independent experiment at HESR (Darmstadt) to measure
antiproton-proton elastic scattering in order to gain the differential
cross section which is a crucial input for the PANDA luminosity determination.
The KOALA experiment will measure the elastically scattered beam particles
in forward area and recoil protons from the target near 90 degress.
One of the recoil detectors has been designed and built. It was installed
and commissioned by measuring proton-proton elastic scattering at COSY in
Juelich.
The data aquisition system is currently running with a small amount of
channels (240 ADC, TDC and scaler channels, plus trigger and synchronisation
logic) with some interesting features. The hardware and the
software concept will be shown. Especially some problems with the
synchronisation and their solutions will be discussed.
