	Funding: Brazilian Ministry of Science, Technology, Innovation and Communication The monochromator is known to be one of the most critical optical elements of a synchrotron beamline. It directly affects the beam quality with respect to energy and position, demanding high stability performance and fine position control. The new high-dynamics DCM (Double-Crystal Monochromator) [1] prototyped at the Brazilian Synchrotron Light Laboratory (LNLS), was designed for the future X-ray undulator and superbend beamlines of Sirius, the new Brazilian 4th generation synchrotron [2]. At this kind of machine, the demand for stability is even higher, and conflicts with factors such as high power loads, power load variation, and vibration sources. This paper describes the system identification work carried out for enabling the motion control and thermal control design of the mechatronic parts composing the DCM prototype. The tests were performed in MATLAB/Simulink Real-Time environment, using a Speedgoat Real-Time Performance Machine as a real-time target. Sub-nanometric resolution and nanometric stability at 300 Hz closed loop bandwidth in a MIMO system were targets to achieve. Frequency domain identification tools and control techniques are presented in this paper.

THPHA182	Common Standards for JavaFX GUI Development and its Application to the Renovation of the CERN Beam Instrumentation Software Portal and Delivery Mechanism	ion, GUI, software, controls	1861
	I. D. Rodis, A. Topaloudis CERN, Geneva, Switzerland
	Until recently, Java GUI development in the CERN Beam Instrumentation Group has followed an ad-hoc approach despite several attempts to provide frameworks and coding standards. Triggered by the deprecation of Java's Swing toolkit, the JavaFX toolkit has been adopted for the creation of new GUIs, and is foreseen for future migration of Swing-based GUIs. To increase homogenisation and encourage modular coding of JavaFX GUIs, libraries have been developed to standardise accelerator context selection, provide inter-component GUI communication and optimise data streaming between the control system and modules that make up an expert GUI. This paper describes how this has allowed the use of model-view-controller techniques and naming conventions via Maven archetypes. It also details the modernisation of the software delivery process and subsequent renovation of the software portal. Finally, the paper outlines a vision to extend the principles applied to this Java GUI development for future Python-based developments.

	A new 60kW thermosiphon fluorocarbon cooling plant has been commissioned to cool the silicon tracker of the ATLAS experiment at the CERN LHC. The thermosiphon operates over a height of 90 metres and is integrated into the CERN UNICOS system and the ATLAS detector control system (DCS). The cooling system uses custom ultrasonic instrumentaton to measure very high coolant vapour flow (up to 1.2 kg/second), to analyse binary gas mixtures and detect leaks. In these instruments ultrasound pulses are transmitted in opposite directions in flowing gas streams. Pulse transit time measurements are used to calculate the flow rate and the sound velocity, which - at a given temperature and pressure - is a function of the molar concentration of the two gases. Gas composition is computed from comparisons of real-time sound velocity measurements with a database of predictions, using algorithms running in the Siemens SIMATIC WinCC SCADA environment. A highly-distributed network of five instruments is currently integrated into the ATLAS DCS. Details of the thermosiphon, its recent operation and the performance of the key ultrasonic instrumentation will be presented.
