Description
The Cherenkov Telescope Array (CTA) is one of the major ground-based
astronomy projects being pursued and will be the largest facility for
ground-based gamma-ray observations ever built. CTA will consist of
two arrays: one in the Northern hemisphere composed of about 20
telescopes, and the other one in the Southern hemisphere composed of
about 100 telescopes, both arrays containing telescopes of several
sizes. A prototype for the Mid-Size Telescope (MST) with a diameter of
12 m has been installed in Berlin and is currently being
commissioned. This prototype is composed of a mechanical structure, a
drive system and mirror facets mounted with powered actuators to
enable active control. Five Charge-Coupled Device (CCD) cameras, and a
wide set of sensors allow the evaluation of the performance of the
instrument.
The design of the control software is following concepts and tools
under evaluation within the CTA consortium in order to provide a
realistic test-bed for the middleware: 1) The readout and control
system for the MST prototype is implemented with the Atacama Large
Millimeter/submillimeter Array (ALMA) Common Software (ACS)
distributed control middleware; 2) the OPen Connectivity-Unified
Architecture (OPC UA) is used for hardware access; 3) MySQL
databases are used for archiving the slow control monitoring data and
operation configuration parameters storage; and 4) the document
oriented MongoDB database is used for an efficient storage of CCD
images, logging and alarm information. In this contribution, the
details on the implementation of the control system for this MST
prototype telescope are described.
