Description

In the past few years a ten channel video diagnostics system was developed, built and installed for Wendestein 7-X stellarator (W7-X). The system is based on EDICAM (Event Detection and Intelligent Camera) CMOS cameras (400 fps @ 1.3 Mpixel).  In the first W7-X experimental campaigh (OP1.1) the video diagnostic  system is not integrated into the central control and data acquisition system of W7-X, therefore the developlment of a user friendly interface became necessary which had to fulfill several requirements.  The system has to manage the setup all cameras (each with four indenpendent region of interests),  the measurement cyclus and the real time storage of the collected data to SSD discs and has to provide live video stream of ten EDICAM camerasin the W7-X control room. The  full bandwidth  stream of the cameras  results in a data rate of approximately 1GB/s for a single camera, and a huge amount of data when W7-X will operate for up-to 30 minutes. These requirementsinvolves the developement of a complex software package able to fulfill all the above mentoined tasks. The software package is organized into two stand-alone pieces: VIDACS (Video Diagnostics Data Acquisition and Control Software) which controls all cameras and EDIDAQ (EDICAM Data Acquistion Software) controlling the individual EDICAMs. This paper will present the detailed design, implementation, testing and the first operation experiences of this software package.
