This presentation will cover the latest developments in the Sardana project and its community, including the new Sardana 3.7 release.
Current work is focused on improving Continuous Scans with support for multiple synchronization descriptions and trigger hierarchies, together with developments related to trajectory integration and shutter control. Additional improvements include...
The TANGO control system is widely used at SOLEIL, yet its administration and operational tooling remain limited, leading to increased complexity in deployment, maintenance, and incident response. This work presents practical developments carried out at Synchrotron SOLEIL to address these challenges.
First, we will introduce Castor, a deployment and orchestration tool designed to...
At MAX IV, we have developed an internal command-line tool, tango-takeoff, to manage the lifecycle of Tango Device Servers via Starter. This tool, now publicly available, is designed to simplify starting, stopping, and restarting device servers in an automated way.
tango-takeoff is integrated into our Ansible roles, enabling automatic deployment and reliable service management across...
There are several ways to store and access configuration in Tango Controls:
- Device and Сlass properties, which are the standard interface for Tango devices;
- Local files for secrets that should not be stored in properties;
- Sardana’s own file format for storing environment variables, e.g., ScanID or Measurement Groups, in addition to device properties for elements;
- Free...
We present HIJ-pyVision, a modular Tango Controls-based software stack developed at HI-Jena in cooperation with S2Innovation for real-time GenTL Vision camera integration in high-power laser experiments.

- Controls cams by GenICam interfase
- HDF5 image storage with metadata like:
- ROI masks, background image, calibrations
- automatic reconnection on camera...
Control systems are inherently asynchronous: devices emit events, commands propagate across networks, and system state evolves continuously. Yet application code interacting with these systems is often written in imperative styles that make complex asynchronous flows difficult to express and maintain.
This talk explores a different approach: applying ReactiveX principles to the Tango...
At SKAO we have a large group of developers building a control system that relies heavily on the Tango event system. Our tests succeed or fail on the delivery of a single event and when that event doesn't come the immediate response is often "Tango events don't work". However, after debugging many the "Tango event system is broken" issues with tools such as ska-tango-event-monitor we have...
At the 39th Tango Community Meeting, I showed that Multiclasses can be a valid approach for complex device servers: one executable, one Jive entry, and a single home for cooperating and inspectable Tango classes. In this talk, I will present the production pattern I use — a single server combining transport classes, protocol classes, device-specific classes, and a generic interface class —...
Voltumna Linux is a custom, layered and immutable Yocto/OpenEmbedded-based distribution developed by the Controls group at Elettra Sincrotrone Trieste for Tango-based accelerator control systems. Now in production on the Elettra storage ring and the FERMI free-electron laser, it supports a heterogeneous fleet of front-ends ranging from VME PowerPC boards to x86 servers, ARM controllers and FPGA SoCs.
Instrumentation Technologies develops and maintains a Tango device
server that integrates the majority of Libera instrumentation (regardless
of their hardware platform) with TANGO-based control systems at accelerator
facilities worldwide.
During years 2024 and 2025, the Libera TANGO adapter has been upgraded
to use TANGO framework 9.5.0. This paper reports the upgrade process...
Modern synchrotron facilities expose thousands of TANGO devices, requiring coordinated control of complex operations from simple queries to fast feedback loops. Elettra 2.0, the upcoming fourth-generation storage ring at Elettra-Sincrotrone Trieste, significantly increases this complexity with orders-of-magnitude higher brilliance, MHz-scale feedback rates, and greatly expanded network...
The Centre for Advanced Laser Applications (CALA) operates the petawatt laser system ATLAS-3000, primarily for applications in particle acceleration. These experiments rely on stable and reproducible laser beam properties to ensure control over the resulting particle beams. At the same time, the system is used by a large number of experimentalists, posing a challenge for maintaining consistent...
At the Centre for Advanced Laser Applications (CALA), the high-power laser system ATLAS 3000 is used for research in laser-driven ion acceleration. In our setup, the laser is focused onto a micrometer-thin liquid water leaf, generating proton bunches with energies of up to 42 MeV at a repetition rate of 1 Hz. However, motion of the liquid leaf target system during operation currently...
It is common to find multiple PLCs controlling and protecting large scientific facilities. Through PLCs, process variables from a wide range of equipment flow across the infrastructure into the control system. Efficiently managing this data becomes increasingly challenging as system complexity grows.
At ALBA, the Modbus protocol has been used to communicate with PLC devices since the...
IC@MS — Integrated Critical Alarms Management Software — is a web-based alarm-management platform for Tango-based scientific facilities. It provides a browser-based operator console for alarm monitoring, acknowledgement, configuration, filtering, history browsing, role-based access and API integration. IC@MS builds on the existing Tango alarm ecosystem rather than replacing it: it can work...
Operating a facility or running an experiment is simple and easy when things are working exactly as expected. But usually they do not. There is always something broken. And there is always something that does something entirely surprising, be it hardware or software.
Would it not be nice to be able to stay on top of such developments? If an operator, remotely or on site, could assess the...
