A Large Scale Cosmic Muon Test Stand — Dmitry Eliseev, Thomas Hebbeker, Markus Merschmeyer, and •Lars Steffen Weinstock — III. Physikalisches Institut A, RWTH Aachen University, Aachen, Germany

The CMS Drift Tubes (DT) system is used to precisely measure the tracks of muons in the barrel region. In order to provide higher acquisition rates, that are required by the phase 2 upgrade, and to add more flexibility to the trigger logic the on-chamber electronics of the DT system are being upgraded. The verification of this new generation of readout electronics requires several test setups using actual DT chambers. For this purpose a large scale cosmic muon test stand is being equipped with new readout electronics and a scintillator based trigger system. The trigger system consists of three layers with plastic scintillator tiles that are read out by silicon photomultipliers (SiPMs) providing fast trigger signals and data for muon track reconstructions. Using this setup several functional tests can be performed on the new DT system.

This talk gives an overview of the cosmic muon test stand and focuses on the trigger system.
