# Trigger performance verification of the FlashCam prototype camera

## TL;DR

This paper verifies the trigger performance of the FlashCam prototype for CTA by comparing laboratory measurements with Monte-Carlo simulations across various trigger parameters and background light conditions.

## Contribution

It introduces a comprehensive comparison method to validate the FlashCam trigger logic using both experimental data and simulations.

## Key findings

- Measured trigger rates match simulations well
- Trigger logic is verified for different background light levels
- Performance expectations are confirmed for on-site operation

## Abstract

FlashCam is a camera proposed for the medium-sized telescopes of the Cherenkov Telescope Array (CTA). We compare camera trigger rates obtained from measurements with the camera prototype in the laboratory and Monte-Carlo simulations, when scanning the parameter space of the fully-digital trigger logic and the intensity of a continuous light source mimicking the night sky background (NSB) during on-site operation. The comparisons of the measured data results to the Monte-Carlo simulations are used to verify the FlashCam trigger logic and the expected trigger performance.
