TUAPL04 | Em# Electrometer Comes to Light | 137 |
|
||
Em# project is a collaboration project between MAX IV Laboratory and ALBA Synchrotron to obtain a high performant four-channel electrometer. Besides the objective of accurate current measurements down to the pico-ampere range, the project pursues to establish a reusable instrumentation platform with time stamped data collection able to perform real time calculations for flexible feedback implementations. The platform is based on a FPGA responsible of acquisition and synchronization where a real-time protocol between the modules has been implemented (Harmony) [*]. The data acquired is transmitted via PCIe to a Single Board Computer with an embedded Linux distribution where high level processing and synchronization with upper levels of Control System is executed. In this proceeding, the reasons that lead to start a complex instrument development instead of using a Commercial On the Shelf (COTS) solution will be discussed. The results of the produced units will be analyzed in terms of accuracy and processing capabilities. Finally, different Em# applications in particle accelerators will be described, further widening the functionality of the current state-of-the-art instrumentation.

TUDPL01 | Reproduce Anything, Anywhere: A Generic Simulation Suite for Tango Control Systems | 280 |
|
||
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.

TUPHA173 | A Web-Based Report Tool for Tango Control Systems via Websockets | 826 |
|
||
Beamlines at Synchrotron Light sources operate 24 hours/day requiring Beamline scientists to have tools to monitor the current state of the Beamline without interfering with the measurements being carried out. The previous web report system developed at ALBA was based on cron tasks querying the Tango Control system and generating html files. The new system integrates all those automatic tasks in a Tornado Tango Device letting the users create their own reports without requiring the intervention of the software support groups. This device runs a Tornado web server providing an html5 web interface to create, customize and visualize its reports in real time (via websockets). Originally designed for the vacuum engineers to monitor the vacuum, is actually used by the scientists and engineers involved in the experiment and the different on-call services to remotely check the beamline overall status. | ||

WEAPL01 | Present and Future of Harmony Bus, a Real-Time High Speed Bus for Data Transfer Between FPGA Cores | 1012 |
|
||
When feedback loops latencies shall be lower than milliseconds range the performance of FPGA-based solutions are unrivaled. One of the main difficulties in these solutions is how to make compatible a full custom digital design with a generic interface and the high-level control software. ALBA simplified the development process of electronic instrumentation with the use of Harmony Bus (HB)*. Based on the Self-Describing Bus, developed at CERN/GSI, it creates a bus framework where different modules share timestamped data and generate events. This solution enables the high-level control software in a Single Board Computer or PC, to easily configure the expected functionally in the FPGA and manage the real-time data acquired. This framework has been already used in the new Em# electrometer**, produced within a collaboration between ALBA and MAXIV, that is currently working in both synchrotrons. Future plans include extending the FPGA cores library, high-level functions and the development of a new auto-generation tool able to dynamically create the FPGA configuration file simplifying the development process of new functionalities.

THPHA169 | Building S.C.A.D.A. Systems in Scientific Installations with Sardana and Taurus | 1820 |
|
||
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. | ||
