Contribution
It presents the performance assessment of the LST-1 camera calibration system (CaliBox) during early commissioning, including preliminary flat field measurements.
Findings
Calibration system achieves uniformity over large dynamic range
Preliminary flat field measurements indicate effective calibration
System performance supports accurate energy reconstruction
Abstract
On October 2018 started the commissioning of the first Large Size Telescope (LST) prototype at the Cherenkov Telescope Array (CTA) northern site at the Observatorio del Roque de los Muchachos, Canary Island of La Palma (Spain). For a precise event energy reconstruction, an LST camera requires a uniform and constant calibration over a large dynamic range, up to photo-electrons (p.e.), for each camera photomultiplier tube (PMT). This paper describes the performance of the LST-1 camera calibration system (named CaliBox) in the first commissioning period and provides preliminary results of measurements of the light flat field
