# LATTES: a new gamma-ray detector concept for South America

## TL;DR

LATTES is a novel hybrid gamma-ray detector concept designed for high-altitude deployment in South America, aiming to improve sensitivity to lower-energy gamma rays and complement existing Cherenkov telescope observations.

## Contribution

It introduces a new hybrid EAS array design with enhanced sensitivity at around 100 GeV, filling a gap in current gamma-ray detection methods.

## Key findings

- Preliminary performance estimates show improved sensitivity at ~100 GeV.
- The detector's wide field of view enables effective transient and variable source detection.
- Expected to complement Cherenkov telescopes in South America.

## Abstract

Currently the detection of Very High Energy gamma-rays for astrophysics rely on the measurement of the Extensive Air Showers (EAS) either using Cherenkov detectors or EAS arrays with larger field of views but also larger energy thresholds. In this talk we present a novel hybrid detector concept for a EAS array with an improved sensitivity in the lower energies ($\sim 100\,$GeV). We discuss its main features, capabilities and present preliminary results on its expected perfomances and sensitivities.This wide field of view experiment is planned to be installed at high altitude in South America making it a complementary project to the planned Cherenkov telescope experiments and a powerful tool to trigger further observations of variable sources and to detect transients phenomena.
