Abstract	A prototype of the ATLAS End-cap Muon Level 1 Trigger system has been constructed and mounted on thin gap chambers, which are used for muon trigger chambers for the ATLAS endcap region. We have tested the system with the chambers using 100 GeV muon beams at CERN SPS H8 beam line. The performance of both the trigger signal generation and the chamber data readout has been evaluated in this configuration. In the beam test, the system has been integrated with the muon central trigger processor interface as well as the ATLAS standard central data acquisition system and detector control system. We present the evaluation results of the system and discuss validity as a level 1 trigger generator system for ATLAS.
