Design and implementation of data acquisition system for THz-FEL facility based on EPICS

This paper describes the Experimental Physics and Industrial Control System (EPICS) with the Channel Archiver. We build the data acquisition system for THz-FEL facility to access the experimental data efficiently through the study of Channel Archiver data archiving and retrieval models, and manage the historical data retrieval with the data recovery tool Archive Viewer. Thus a convenient storage and retrieval method is established for large amounts of data generated by the facility.
