| WEPGW073 | Control System for Lasers at Hilase | 2641 |
|
||
| We present the current state of the HiLASE Centre control system developed in cooperation with Cosylab. The aim of the development is to build a control system which would be in charge of the operation of kW-class in-house-developed laser beamlines. These beamlines deliver picosecond pulses with repetition rates between 1 kHz and 1 MHz and high-energy nanosecond pulses at 10 Hz. A generic control system architecture is presented, which can either support full-size development lasers or compact industrial versions. The EPICS control system work focuses on image acquisition and processing, vacuum control, provision of timing, archiving and user interfaces. HiLASE provides high-level requirements, Cosylab complements them, provides the design of the solution and implementation. Delivery is performed during on-site visits where a test plan is executed for acceptance. This approach relieves HiLASE of the need to hire and manage their own team while retaining full control over the functionality through requirements and acceptance approval. Cosylab complements HiLASE with self-managed teams that deliver to specification. | ||

| WEPGW074 | MYRRHA DAQ Development | 2645 |
|
||
| An approach to a generic Data Acquisition (DAQ) solution for the MYRRHA test stand at Louvain-la-Neuve (Belgium) will be described in this paper. Need for better sampling performance, signal quality, arbitrary processing and storage of measurements was a motivation for this work. A full integration of the DAQ system in the global EPICS control environment was a strong requirement. An intermediate DAQ platform was put in place to satisfy the control and experiment needs. The NI PXI platform is selected to minimize integration and development effort. NI LabVIEW is used to create a generic DAQ application. CALab library supported by BESSY is used to connect LabVIEW and EPICS. CSS GUI provides the user with the necessary control, visualization and configuration capability. The technical and organizational approach to the collaboration will be detailed in the paper. Necessary customizations of CSS and CALab and experience on using NI PXI for DAQ platform will be explained. | ||

| THPTS054 | A Novel Approach to Triggering and Beam Synchronous Data Acquisition | 4224 |
|
||
|
SwissFEL, the new Free-Electron Laser facility is a 740 m long accelerator with the goal of providing pulses of light between 6 and 30 fs long at a wavelength of 1 to 7 Å at 100 Hz*. To support shot-to-shot photon diagnostic* and link the measurements to other measurements along the machine that belong to the same machine pulse, a new triggering and data acquisition system was developed. A new protocol was introduced which allows deterministic triggering, configuration and data transfer via one full-duplex optical connection. The measurement data is stamped with an unique pulse identifier, delivered from the SwisFEL Timing System**. A readout and control interface was developed to support data delivery to the Data Acquisition Dispatching Layer* and for controlling the system.

| WEPGW007 | Progress of the Machine Control Upgrade at COSY/JüLICH | 2473 |
|
||
| The Cooler Synchrotron COSY operated at the Research Center Jülich is undergoing staged machine control upgrades driven by the requirements of the JEDI (Jülich Electric Dipole moment Investigations) collaboration. The upgrades aim towards better beam control e.g. beam orbit, tune, and chromaticity control improvements. A better orbit control was achieved through the upgrade of BPM electronics and migration from initial Tcl/Tk based control system to Control System Studio (CSS) utilizing EPICS. Currently, a design for improved beam tune control is in development. The main part of work is the transition towards a faster and less restrictive magnet control. It further includes improved tune measurement tools as well as the migration of control for quadrupole magnets to EPICS. Ultimately the control of all systems should be centralized around EPICS to enable ease of operation, automation, setup of services, etc. The decision path, technical details of the upgrade and performance of the upgraded sub-systems are presented. We also showcase how the COSY team’s physics and research goals are complemented by Cosylab’s technical design and implementation to form a synergetic collaboration. | ||
