Description
We report a measurement of the all-particle cosmic-ray energy spectrum with the ALPAQUITA array, the prototype of the ALPACA experiment, located at an altitude of 4,740 m on Mount Chacaltaya in Bolivia. The array consists of 97 scintillation detectors deployed on a 15 m grid. Using approximately 240 days of data, we measure the cosmic-ray flux in the energy range from 10 TeV to 300 TeV. This energy range overlaps with space-based measurements and indirect measurements by ground-based air-shower arrays. In this contribution, we present the event reconstruction, the energy estimation, and the detector performance evaluation, and show the resulting all-particle spectrum. We also compare our results with previous direct and indirect measurements.
