Data Acquisition system and Link and Data Aggregator for the CALICE Analogue Hadron Calorimeter — •Julien Caudron, Lennart Adam, Bruno Bauss, Volker Büscher, Phi Chau, Reinhold Degele, Karl-Heinrich Geib, Sascha Krause, Yong Liu, Lucia Masetti, Ulrich Schäfer, Rouven Spreckels, Stephan Tapprogge, and Rainer Wanke for the CALICE-D collaboration — Johannes-Gutenberg Universität, Mainz
The Analogue Hadron Calorimeter (AHCAL) is one of the several calorimeter designs developped by the CALICE collaboration for future linear colliders. It is a high granularity sampling calorimeter with plastic scintillator tiles of 3 × 3 cm2, adding up to ∼ 8’000’000 sensors. This large amount of channels requires a powerful data acquisition system (DAQ). In this DAQ system, the Link and Data Aggregator module (LDA) acts as an intermediate component to group together several layers units, dispatching control signals and merging data. A first LDA design (mini-LDA), intended to be flexible but limited to a small number of layers, has been successfully used during the end-of-the-year 2014 CERN Test Beam program. A second prototype (wing-LDA), compatible with a complete detector design, is operating during the Test Beam program of 2015. This talk will present the current status of the DAQ and the LDA, with recent results from Test Beam and future plans.
