Water Cherenkov detector optimization for space weather studies in Antarctic.

During the last two Peruvian summer campaigns in the Antarctica (2018 and 2019), two separate prototype water Cherenkov detectors of the LAGO project have been tested. As at high latitudes the lower geomagnetic shielding allows for the observation of cosmic rays lower than those at middle latitudes, the installation of a detector in the Antarctica is important for the development of the LAGO space weather program.
The objectives fulfilled in the second summer campaign were: a general improvement of the design of the detectors, wi-fi data transmission, autonomous operation, the elimination of light leaking and the optimization of the geometry for better separation of the electromagnetic/muonic components measured in the detector.
A comparison between the data obtained in the two Antarctic campaigns is shown, making emphasis in the measured flows and the strategy of using a second trigger level in the acquisition stage in order to perform a pre-processing of the data.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
