Analysis techniques and performance of the Domino Ring Sampler version 4 based readout for the MAGIC telescopes

TL;DR

This paper evaluates the performance and analysis methods of the Domino Ring Sampler v4 readout system used in MAGIC telescopes, focusing on baseline, noise, cross-talk, linearity, and timing accuracy improvements.

Contribution

It introduces new analysis techniques and performance assessments for the upgraded Domino Ring Sampler v4 system, comparing it with the previous v2 version used in MAGIC II.

Findings

Improved signal extraction performance with the new system

Detailed characterization of baseline, noise, and cross-talk behavior

Enhanced time resolution for better event reconstruction

Abstract

Recently the readout of the MAGIC telescopes has been upgraded to a new system based on the Domino Ring Sampler version 4 chip. We present the analysis techniques and the signal extraction performance studies of this system. We study the behaviour of the baseline, the noise, the cross-talk, the linearity and the time resolution. We investigate also the optimal signal extraction. In addition we show some of the analysis techniques specific to the readout based on the Domino Ring Sampler version 2 chip, previously used in the MAGIC II telescope.
