The TANGO Controls Framework continues to improve. This paper will describe how TANGO kernel development has evolved since the last ICALEPCS conference. TANGO kernel projects source code repositories have been transferred from subversion on to git on Continuous integration with Travis CI and the GitHub pull request mechanism should foster external contributions. Thanks to the TANGO collaboration contract, parts of the kernel development and documentation have been sub-contracted to companies specialized in TANGO. The involvement of the TANGO community helped to define the roadmap which will be presented in this paper and also led to the introduction of Long Term Support versions. The paper will present how the kernel is evolving to support pluggable protocols - the main new feature of the next major version of TANGO.

  Synchrotron Light Sources are required to operate on 24/7 schedules, while at the same time must be continuously upgraded to cover scientists needs of improving its efficiency and performance. These operation conditions impose rigid calendars to control system engineers, reducing to few hours per month the maintenance and testing time available. The SimulatorDS project has been developed to cope with these restrictions and enable test-driven development, replicating in a virtual environment the conditions in which a piece of software has to be developed or debugged. This software provides devices and scripts to easily duplicate or prototype the structure and behavior of any Tango Control System, using the Fandango python library* to export the control system status and create simulated devices dynamically. This paper will also present first large scale tests using multiple SimulatorDS instances running on a commercial cloud.

WEBPL06 Sardana Based Continuous Scans at ALBA - Current Status 1067

  A significant part of the experiments run at Alba Synchrotron* involve scans. The continuous scans were developed first ad hoc and latter the controls group dedicated important efforts to standardize them across the Alba instruments, enhancing the overall performance and allowing the users to better exploit the beamtime**. Sardana***, the experiment control software used at Alba, among other features, aims to provide a generic way of programming and executing continuous scans. This development just achieved a major milestone - an official version with a stable API. Recently the Alba instruments were successfully upgraded to profit from this release. In this paper we describe the evolution of these setups as well as the new continuous scan applications run at Alba. On the one hand, the most relevant hardware solutions are presented and assessed. On the other hand the Sardana software is evaluated in terms of its utility in building the continuous scans setups. Finally we discuss the future improvements plan designed to satisfy the ever-increasing requirements of the scientists.

THPHA084 Synchrotron Master Frequency Reconstruction for Sub-Nanosecond Time-Resolved XMCD-PEEM Experiments 1577

  The timing and synchronization system at the ALBA synchrotron facility is based on the well-established event-based model broadly used in the particle accelerator facilities built in the last decade. In previous systems, based on signal model architecture, the master frequency was distributed using a direct analog signal and delayed at each target where the triggers were required. However, such strategy has proven to be extremely expensive and non-scalable. In the event-based model, the data stream is generated at a continuous rate, synchronously with the master clock oscillator of the accelerator. This strategy improves the flexibility for tuning the trigger parameters remotely and reduces the costs related to maintenance tasks. On the other hand, the absence of the pure RF signal distributed in the experimental stations implies much more complexity in the performance of time-resolved experiments. Abstract here explain how these difficulties have been overcome in the ALBA timing system in order to allow the signal reconstruction of the RF master frequency at the CIRCE beamline.

  Sardana and Taurus form a python software suite for Supervision, Control and Data Acquisition (SCADA) optimized for scientific installations. Sardana and Taurus are open source and deliver a substantial reduction in both time and cost associated to the design, development and support of control and data acquisition systems. The project was initially developed at ALBA and later evolved to an international collaboration driven by a community of users and developers from ALBA, DESY, MAXIV and Solaris as well as other institutes and private companies. The advantages of Sardana for its adoption by other institutes are: free and open source code, comprehensive workflow for enhancement proposals, a powerful environment for building and executing macros, optimized access to the hardware and a generic Graphical User Interface (Taurus) that can be customized for every application. Sardana and Taurus are currently based on the Tango Control System framework but also capable to inter-operate to some extend with other control systems like EPICS. The software suite scales from small laboratories to large scientific institutions, allowing users to use only some parts or employ it as a whole.
