Description

At the Fritz-Haber-Institute PVAccess is used for new experiments to realize high data rates (streaming).

Using RTEMS as the real-time operating system, a custom PVData structure captures data deterministically from a newly constructed fast scanning tunnelling microscope. The recorded data is sent with PVAccess to a python server.
The python server stores the data in a special file format for online analysis. The metadata is stored as a Normative Type structure in an instance of the Archiver Appliance.
