Description

Currently a new experiment is being built for the measurement of the neutron
electric dipole moment at PSI called n2EDM.
Compared to its predecessor, many improvements will be made not only to
the apparatus itself, but also to the supervisory control and data acquisition
system.
For nEDM it is essential to not only record, but also to influence the
experiment automatically which incorporates decisions that are based on
previous measurements.

The concept is completely modular, thus development can be done in
parallel, and new devices can be added easily - even while the
experiment is running.
The modules are connected via network using Standard Commands for
Programmable Instruments (SCPI) over TCP for messaging.
Data sampling and recording is done simultaneous. Synchronization is
achieved via Precision Time Protocol (PTP).
Multiple control stations are possible and any graphical user interface
is separated operation and recording.
A simple command language for arbitrary sequences, loops and conditional
execution is available.

While the framework is clearly optimised for an nEDM measurement, it may
be used for other experiments with similar scale and measurement procedure.
