| WPO016 | Magnet Power Supply Control Mockup for the SPES Project | 66 |
|
||
|
The Legnaro National Laboratories employs about 100 Magnet Power Supplies (MPSs). The existing control infrastructure is a star architecture with a central coordinator and ethernet/serial multiplexers. In the context of the ongoing SPES project, a new magnet control system is being designed with EPICS [1, 2] based software and low cost embedded hardware. A mockup has been setup as a test stand for validation. The paper reports a description of the prototype, together with first results.

| WPO017 | IFMIF EVEDA RFQ Local Control System to Power Tests | 69 |

In the IFMIF EVEDA project, normal conducting Radio Frequency Quadrupole (RFQ) is used to bunch and accelerate a 130 mA steady beam to 5 MeV. RFQ cavity is divided into three structures, named super-modules. Each super-module is divided into 6 modules for a total of 18 modules for the overall structure. The final three modules have to be tested at high power to test and validate the most critical RF components of RFQ cavity and, the control system itself. The choice of the last three modules is due to the fact that they will operate in the most demanding conditions in terms of power density (100 kW/m) and surface electric field (1.8*Ekp). The Experimental Physics and Industrial Control System (EPICS) environment [1] provides the framework to control any equipment connected to it. This paper report the usage of this framework to the RFQ power tests at Legnaro National Laboratories [2].

| WPO018 | Upgrade of Beam Diagnostics System of ALPI-PIAVE Accelerator's Complex at LNL | 72 |
|
||
| The beam diagnostics system of ALPI-PIAVE accelerators has been recently upgraded by migrating the control software to EPICS. The system is based on 40 modules each one including a Faraday cup and a beam profiler made of a couple of wire grids. The device's insertion is controlled by stepper motors in ALPI and by pnematic valves in PIAVE. To reduce the upgrade costs the existing VME hardware used for data acquisition has been left unchanged, while the motor controllers only have been replaced by new units developed in house. The control software has been rebuilt from scratch using EPICS tools. The operator interface is based on CSS; a Channel Archiver based on .. has been installed to support the analysis of transport setup during tests of new beams. The ALPI-PIAVE control system is also a bench test for the new beam diagnostics under development for the SPES facility, whose installation is foreseen in mid 2015. | ||
| FPO014 | New Data Archive System for SPES Project Based on EPICS RDB Archiver with PostgreSQL Backend | 191 |
|

|
SPES project [1] is a ISOL facility under construction at INFN, Laboratori Nazionali di Legnaro, which requires the integration between the accelerator systems actually used and the new line composed by the primary beam and the ISOL target. As consequence, a migration from the actual control system to a new one based on EPICS [2] is mandatory to realize a distributed control network for the new facility. One of the first implementation realized for this purpose is the Archiver System, an important service required for experiments. Comparing information and experiences provided by other Laboratories, an EPICS Archive System [3] based on PostgreSQL is implemented to provide this service. Preliminary tests are done with a dedicated hardware and following the project requirements. After these tests used to determinate a good configuration for Database and EPICS Application, the system is going to be moved in production, where it will be integrated with the first subsystem upgraded to EPICS. Dedicated customizations are made to the application for providing a simple user experience in managing and interact with the archiver system.
