Abstract
We present the preliminary results obtained in the development of the new data acquisition system
(DAQ) that will be used by the LAGO Collaboration. According to the requirements of the water
Cherenkov detectors (WCD) used in LAGO, the new system must be capable of recording fast
pulses (∼ ns) from a photomultiplier (PMT), control the high voltage level applied to it, in addition
to monitoring the atmospheric conditions in which the data were taken. We show some of the
figures of merit indicating the performance of the new system working with a WCD. The DAQ
system is based on a commercial board plus a custom made interface board. The implementation
includes scalers, sub-scalers, an automatic baseline correction algorithm, pressure & temperature
sensing, geolocalization, an external trigger and the capability to set and monitor the high voltage
applied to the PMT. The flexibility in the design of the system allows to adapt it to different
particle detector technologies, such as silicon photomultipliers (SiPMs), resistive plate chambers
(RPC) and scintillators. Preliminary results prove the validity, reliability and high performance of
the system.
