Data acquisition and slow control interface for the Mu 2 e 5 experiment 6

The Mu2e experiment at the Fermilab Muon Campus will search for the coherent 23 neutrinoless conversion of a muon into an electron in the field of an aluminum nucleus with a 24 sensitivity improvement by a factor of 10,000 over existing limits. The Mu2e Trigger and Data 25 Acquisition System (TDAQ) uses otsdaq as the online Data Acquisition System (DAQ) solution. 26 Developed at Fermilab, otsdaq integrates both the artdaq DAQ and the art analysis frameworks for 27 event transfer, filtering, and processing. otsdaq is an online DAQ software suite with a focus on 28 flexibility and scalability and provides a multi-user, web-based, interface accessible through a web 29 browser. The data stream from the detector subsystems is read by a software filter algorithm that 30 selects events which are combined with the data flux coming from a Cosmic Ray Veto System. The 31 Detector Control System (DCS) has been developed using the Experimental Physics and Industrial 32 Control System (EPICS) open source platform for monitoring, controlling, alarming, and archiving. 33 The DCS System has been integrated into otsdaq. A prototype of the TDAQ and the DCS systems 34 has been built at Fermilab’s Feynman Computing Center. In this paper, we report on the progress 35 of the integration of this prototype in the online otsdaq software. 36
