  The Elettra control system has been running since 1993. The controllers of the storage ring power supplies, still the original ones, have become obsolete and are no more under service. A renewal to overcome these limitations is foreseen. A prototype of the new controllers based on the BeagleBone embedded board and an in-house designed ADC/DAC carrier board, has been installed and tested in Elettra. A Tango device server running in the BeagleBone is in charge of controlling the power supply. In order to transparently integrate the new Tango controlled power supplies with the existing Remote Procedure Call (RPC) based control system, a number of software tools have been developed, mostly in the form of Tango devices and protocol bridges. This approach allows us to keep using legacy machine physics programs when integrating the new Tango based controllers and to carry out the upgrade gradually with less impact on the machine operation schedule.

WPO008 An Extensible Equipment Control Library for Hardware Interfacing in the FAIR Control System controls, software, hardware, framework 49

  In the FAIR control system the SCU (Scalable Control Unit, an industry PC with a bus system for interfacing electronics) is the standard front-end controller for power supplies. The FESA-framework is used to implement front-end software in a standardized way, to give the user a unified look on the installed equipment. As we were dealing with different power converters and thus with different SCU slave card configurations, we had two main things in mind: First, we wanted to be able to use common FESA classes for different types of power supplies, regardless of how they are operated or which interfacing hardware they use. Second, code dealing with the equipment specifics should not be buried in the FESA-classes but instead be reusable for the implementation of other programs. To achieve this we built up a set of libraries which interface the whole SCU functionality as well as the different types of power supplies in the field. Thus it is now possible to easily integrate new power converters and the SCU slave cards controlling them in the existing equipment software and to build up test programs quickly.

  Control system for the Taiwan Photon Source (TPS) project has been implemented. The accelerator system began to be commissioning from third quarter of 2014. Final integration test of each subsystem will be done. The EPICS was chosen as the TPS control system framework. The subsystems control interfaces include event based timing system, Ethernet based power supply control, corrector power supply control, PLC-based pulse magnet power supply control and machine protection system, insertion devices motion control system, various diagnostics, and etc. The standard hardware components had been installed and integrated, and the various IOCs (Input Output Controller) had been implemented as various subsystems control platforms. Development and test of the high level and low level software systems are in final phase. The efforts will be summarized at this report.

  The Hefei Light Source (HLS) is a VUV synchrotron radiation light source. It is upgraded recently to improve its performance. The power supply control system is a part of the HLS upgrade project. Five soft IOC applications running on the virtual machine are used to control 190 power supplies via MOXA's serial-to-Ethernet device servers. The power supply control system has been under operation since November 2013, and the operation results show the power supply control system is reliable and can satisfy the demands of slow orbit feedback with the frequency of 1Hz.

  The magnetic system of Novosibirsk Free electron laser containing large amount of magnetic elements, feed by power supplies of different types. The time stability of output current of these power supplies is directly influence on coherent radiation parameters, and operation of whole FEL facility. Therefore, system for diagnostics of power supplies state, integrated to common FEL control system, was developed. The main task of this system is to analyze output current of power supply, determinate its time stability value. Also this system is able to determinate the amplitude and frequency of output current ripples, if they have a place for particular power supply, and display obtained results. The main architecture, some other capabilities, and results of usage of this system, are described in this paper.

FPO031 Power Supplies Transient Recorders for Post-Mortem Analysis of BPM Orbit Dumps at Petra-III controls, synchrotron, emittance, operation 225

  PETRA-III is a 3rd generation synchrotron light source dedicated to users at 14 beam lines with 30 instruments. The storage ring is presently modified to add 12 beam lines. PETRA III was operated with several filling modes such as 40, 60, 480 and 960 bunches with a total current of 100mA at electron beam energy of 6 GeV. The horizontal beam emittance is 1 nmrad while a coupling of 1% amounts to a vertical emittance of 10 pmrad. During a user run Machine Protection System (MPS) may trigger an unscheduled beam dump if transients in the current of magnet power supplies are detected which are above permissible limits. The trigger of MPS stops the ring buffers of the 226 BPM electronics where the last 16384 turns just before the dump are stored. These data and transient recorder data of Magnet Power Supply Controllers are available for a post-mortem analysis. Here we discuss in detail the functionality of a Java GUI used to investigate the transient behavior of the differences between set and readout values of different power supplies to find out the responsible power supply that might have led to emittance growth, fluctuations in orbits or beam dumps seen in a post-mortem analysis.
