Compatibility of trigger and timing between the non-upgraded and the upgraded electronics of the Pierre Auger Observatory. — •Fabio Convenga for the Pierre Auger collaboration — Karlsruher Institut für Technologie (IAP), Karlsruhe, Germany

The surface detectors of the Pierre Auger Observatory are being upgraded by adding new detectors and replacing electronics.

The upgraded electronics, dubbed Upgraded Unified Board (UUB), is able to acquire data from the new detectors. It includes an improved GPS receiver, a higher sampling rate, and a more powerful logic capacity.

The new features of UUB made it possible to introduce new types of triggers. Despite this, to ensure backward compatibility, pre-upgrade triggers are implemented using digitally filtered and downsampled waveforms to simulate the triggering behavior in the non-upgraded stations.

The logic functionality of the UUB also includes a module for event timing. The fundamental architecture of this module is parallel to that used in non-upgraded electronics. The on-board software that manages the module is similar to that of the non-upgraded electronics, with minor modifications required for the new UUB hardware.

In this talk, we will present the first analysis on the compatibility of the triggering efficiency and timing focusing on two neighboring stations one with the non-upgraded electronics and the other with the UUB.
