This work started in the context of NSLS2 project at Brookhaven National Laboratory. The NSLS2 control system foresees a very high number of PV variables and has strict requirements in terms of archiving/retrieving rate: our goal was to store 10K PV/sec and retrieve 4K PV/sec for a group of 4 signals. The HyperArchiver is an EPICS Archiver implementation engined by Hypertable, an open source database whose internal architecture is derived from Google's Big Table. We discuss the performance of HyperArchiver and present the results of some comparative tests.

The beam diagnostics system currently in use at LNL in the superconducting Linac has been upgraded for the SPES project. The control software has been rewritten using EPICS tools and a new emittance meter has been developed. The beam detector is based on wire grids, the IOC is implemented in a VME system running under Vxworks and the graphic interface is based on CSS. The system is now in operation in the SPES Target Laboratory for the characterization of beams produced by the new ion source.

Experience in Using Linux Based Embedded Controllers with EPICS Environment for the Beam Transport in SPES Off–Line Target Prototype

EPICS [1] was chosen as general framework to develop the control system of SPES facility under construction at LNL [2]. We report some experience in using some commercial devices based on Debian Linux to control the electrostatic deflectors installed on the beam line at the output of target chamber. We discuss this solution and compare it to other IOC implementations in use in the Target control system.

The SPES off-line front-end apparatus involves a number of subsystems and procedures that are potentially dangerous both for human operators and for the equipments. The high voltage power supply, the ion source complex power supplies, the target chamber handling systems and the laser source are some example of these subsystems. For that reason, a safety control system has been developed. It is based on Schneider Electrics Preventa family safety modules that control the power supply of critical subsystems in combination with safety detectors that monitor critical variables. A Programmable Logic Controller (PLC), model BMXP342020 from the Schneider Electrics Modicon M340 family, is used for monitoring the status of the system as well as controlling the sequence of some operations in automatic way. A touch screen, model XBTGT5330 from the Schneider Electrics Magelis family, is used as Human Machine Interface (HMI) and communicates with the PLC using MODBUS-TCP. Additionally, an interface to the EPICS control network was developed using a home-made MODBUS-TCP EPICS driver in order to integrate it to the control system of the Front End as well as present the status of the system to the users on the main control panel.
