  In modern scientific instruments like ALBA, ELETTRA or Synchrotron Soleil the monitoring and tuning of thousands of parameters is essential to drive high-performing accelerators and beamlines. To keep tracks of these parameters and to manage easily large volumes of technical data, an archiving service is a key component of a modern control system like Tango [1]. To do so, a high-availability archiving service is provided as a feature of the Tango control system. This archiving service stores data coming from the Tango control system into MySQL [2] or Oracle [3] databases. Tree sub-services are provided: An historical service with an archiving period up to 10 seconds; a short term service providing a few weeks retention with a period up to 100 milliseconds; a snapshot service which takes "pictures" of Tango parameters and can reapply them to the control system on user demand. This paper presents how to obtain a high-performance and scalable service based on our feedback after years of operation. Then, the deployment architecture in the different Tango institutes will be detailed. The paper conclusion is a description of the next steps and incoming features which will be available in the next future.

FERMI@Elettra is a single-pass Free Electron Laser (FEL) user-facility covering the wavelength range from 100 nm to 4 nm. The facility is located in Trieste, Italy, nearby the third-generation synchrotron light source Elettra. Three experimental stations, dedicated to different scientific areas, have been installed installed in 2011: Low Density Matter (LDM), Elastic and Inelastic Scattering (EIS) and Diffraction and Projection Imaging (DiProI). The experiment control and data acquisition system is the natural extension of the machine control system. It integrates a shot-by-shot data acquisition framework with a centralized data storage and analysis system. Low-level applications for data acquisition and online processing have been developed using the Tango framework on Linux platforms. High-level experimental applications can be developed on both Linux and Windows platforms using C/C++, Python, LabView, IDL or Matlab. The Elettra scientific computing portal allows remote access to the experiment and to the data storage system.

  Mango is an online tool based on QTango that allows easy development of graphical panels ready to run without need to be compiled. Developing with Mango is easy and fast because widgets are dragged from a widget catalogue and dropped into the Mango container. Widgets are then connected to the control system variables by choosing them from a Tango device list or by dragging them from any other running application built with the QTango library. Mango has also been successfully used during the FERMI@Elettra commissioning both by machine physicists and technicians.

FERMI@Elettra is a Free Electron Laser (FEL) based on a 1.5 GeV linac presently under commissioning in Trieste, Italy. Three PLC-based systems communicating to each other assure the protection of machine devices and equipment. The first is the interlock system for the linac radiofrequency plants; the second is dedicated to the protection of vacuum devices and magnets; the third is in charge of protecting various machine components from radiation damage. They all make use of a distributed architecture based on fieldbus technology and communicate with the control system via Ethernet interfaces and dedicated Tango device servers. A complete set of tools including graphical panels, logging and archiving systems are used to monitor the systems from the control room.

FERMI@Elettra is a new 4th-generation light source based on a single pass Free Electron Laser (FEL). In order to ensure the feasibility of the free electron lasing and the quality of the produced photon beam, a high degree of stability is required for the main parameters of the electron beam. For this reason a flexible real-time feedback framework integrated in the control system has been developed. The first implemented bunch-by-bunch feedback loop controls the beam trajectory. The measurements of the beam position and the corrector magnet settings are synchronized to the 50 Hz linac repetition rate by means of the real-time framework. The feedback system implementation, the control algorithms and preliminary close loop results are presented.

FERMI@Elettra is a new 4th-generation light source based on a seeded Free Electron Laser (FEL) presently under commissioning in Trieste, Italy. It is the first seeded FEL in the world designed to produce fundamental output wavelength down to 4 nm with High Gain Harmonic Generation (HGHG). Unlike storage ring based synchrotron light sources that are well known machines, the commissioning of a new-concept FEL is a complex and time consuming process consisting in thorough testing, understanding and optimization, in which a reliable and powerful control system is mandatory. In particular, integrated shot-by-shot beam manipulation capabilities and easy to use high level applications are crucial to allow an effective and smooth machine commissioning. The paper reports the status of the control system and the experience gained in two years of alternating construction and commissioning phases.
