MIDAS is a data acquisition package developed at the Paul Scherrer Institute, Switzerland, and TRIUMF, Canada.

MIDAS (Maximum Integration Data Acquisition System) has been developed as a general purpose data acquisition system for small and medium scale experiments originally by Stefan Ritt in 1993, followed by Pierre-André Amaudruz in 1996.

Drivers exist for CAMAC, VME, Fastbus, High Voltage Crates, GBIB and several PC plug-in DAQ boards.

The online data can be presented by PAW as histograms and N-tuples as well as by ROOT.

A dedicated HTTP server gives fast Web access for experiment control and to access the slow control system including a graphical representation of variable trends (history display).
