SOLEIL II status report
Since 2008, SOLEIL is in operation providing users with access to a wide range of experimental techniques thanks to its 29 beamlines, covering a broad energy range from THz to hard X-ray. In response to new scientific and societal challenges, the construction phase of the SOLEIL II project is set to commence in 2025. This project aims to develop an ambitious Diffraction Limited Storage Ring (DLSR) that will enhance brilliance, coherence, and flux. Additionally, the upgrade will include the improvement of beamlines in a later phase. Throughout this upgrade, the TANGO control system will continue to serve as the main control system for managing the accelerator and beamlines. It will be seamlessly integrated into the ongoing digital transformation, which is aimed at addressing future scientific challenges.
As collaboration is always a valuable asset in projects as stimulating as SOLEIL II. We would be delighted to welcome you to join SOLEIL for the 38th TANGO collaboration meeting, where we actively encourage the development and exchange of ideas.

PALLAS control command a Tango case study for a laser-plasma accelerator test facility
Laser wakefield acceleration (LWFA) is a promising approach for generating accelerating fields three orders of magnitude larger than what is currently achieved in standard RF cavities. Spectacular progress has been made during the last 15 years in understanding the physics involved in laser-plasma accelerators. The transition from demonstration experiments to accelerator beamline is observed in many high-intensity laser labs [1]. In this context at IJClab, the PALLAS (Prototyping Accelerator based on Laser-Plasma technology) project [2] aims to build a demonstrator of laser-plasma injector operating at 10Hz delivering an electron beam of 200 MeV, >30 pC, 1 mm.mrad emittance, an energy spread < 5%, and a bunch length in the femtosecond range with stability and reliability comparable to conventional RF electron accelerator. To this end, we focus on three particular areas of accelerator development: control of the laser driver, plasma target and complete characterisation of the electron bunch phase space. We will report on the progress in developing a complete control and acquisition system under Tango for the accelerator [3], incorporating a 50TW Amplitude laser driver. We will discuss the challenges of implementing the Tango control system.

Tango v10 and IDLv6
A release candidate for Tango V10 (cppTango and PyTango) is expected to be made available during this community meeting. It is a release with new features that we announced at the previous community meeting. To implement the new features we had to modify the Tango IDL interface for the first time in 10 years. We believe that the demo that is embedded in this talk will show that it has been worth it to introduce a new major Tango version number.

Debugging devices in the cloud: Logs + Events
In the SKA software pipelines, artefacts from test execution contain logs (amongst others) from the pipeline which are very useful for debugging errors either from ongoing code changes or flaky tests. The success of finding the root cause for errors is typically a function of how good the logging is in the running device; however, more data points could also be beneficial. For this use case, there are four devices (at the moment) delivering a mid telescope element known as Dish LMC. The master device in Dish LMC needs to track and respond to events from the subservient devices to report the state of the dish. And having a "time machine" of events at any point enhances debugging greatly. In our integration environment, an archiver is deployed to store events from devices as they are exercised. Though helpful, it does not provide developers an immediate reference point to look when debugging issues on the staging environment. This talk demonstrates how to generate additional pipeline artefacts from device events to aid in debugging.

The evolution and roadmap of the Taranta project
The Taranta project, a collaboration between the MaxIV Institute and SKAO within the Tango Collaboration, presents a web-based, no-code approach for creating graphical interfaces dedicated to monitoring and controlling Tango-based systems. Through an active development phase and close collaboration with the community, the software has seen the introduction of advanced features and a code refactor to enhance functionality, user experience, performance, and testability.
Currently, the software has matured to a level enabling adoption in both the daily operations of MaxIV synchrotron beamlines and the developmental phases of the SKA project. To facilitate users in increasingly comprehensive utilization, new features have been implemented, such as the ability to access devices from different Tango databases within a single dashboard. Architectural improvements have also been made to seamlessly integrate applications like Synoptic into Taranta, allowing for the integration of third-party data sources. Additional developments and improvements have been introduced in response to user needs.
Beyond these aspects, the presentation will delve into one of the most significant challenges faced—meeting the demands from institutes with diverse scientific purposes and project stages. This encompasses considerations of architecture, component numbers, and operator skill sets. The presentation will then delve into lessons learned, emphasizing the importance of adaptability and continuous improvement in a dynamic collaborative environment. The strategy for defining the roadmap will be discussed, with a focus on producing increasingly comprehensive GUIs tailored to the specific requirements of the users.Speakers: Mr Helder Ribeiro (Atlar Innovation / SKAO), Matteo Canzari (INAF), Vincent Hardion (MAX IV Laboratory), Yimeng Li -

TANGO Controls: Exploring visual programming to Kubernetes deployments
This paper explores the feasibility of a web-based interface designed to streamline the creation and deployment of TANGO Controls device servers on Kubernetes clusters through visual programming. The proposed interface aims to minimize the need for extensive boilerplate coding, offering an intuitive method for constructing device functionalities using drag-and-drop code blocks. This exploratory study assesses the interface's ability to facilitate the rapid development and deployment of devices or entire projects. Additionally, the system accommodates the integration of custom code to extend the basic generated functionalities, providing flexibility in device behavior. By abstracting the complexities of Kubernetes and TANGO Controls, this platform proposes a potential reduction in development time and complexity, making sophisticated control systems more accessible to developers with varying levels of expertise. The ultimate goal is to evaluate the practicality and efficiency of this approach in a real-world setting, identifying areas for further refinement and potential integration into existing control system frameworks.

Tools for testing your beamline
As the MAX IV facility is maturing, expectations on beamlines are also rising, not least in terms of reliability. The controls team decided to build "checkup"; a simple, general toolset for implementing a test suite for a beamline, using pytest and pytango. Some use cases: "pre-flight" checks before a beamtime starts; when switching between experiments; after commissioning or starting up from shutdown. I'll present some background, the tool itself, and some initial results.
