MIDAS is a data acquisition package developed at the Paul Scherrer Institute, Switzerland, and TRIUMF, Canada. It was designed for particle detectors using CAMAC and VMEbus hardware.

Description

MIDAS (Maximum Integration Data Acquisition System) has been developed as a general purpose data acquisition system for small and medium scale experiments originally by

GPL

.

The experiment complexity ranges from test systems, where a single PC is connected to CAMAC via a PC-CAMAC interface, to experiments with several front-end computers and analysis nodes. The system currently runs under

TCP/IP sockets

.

A speed-optimized RPC layer is used for data exchange, with which sustained data rates of 980 kB/s (

1000BASE-T). An integrated slow control system contains a fast online database and a history system. Drivers exist for CAMAC, VME, Fastbus, High Voltage Crates, GBIB and several PC plug-in DAQ boards. A framework is supplied which can be extended by user code for front-end readout on one side and data analysis on the other side. 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).
