Charge Breeder Control
ECR Control System Architecture The control system is being developed using a prototype of the new LNL EPICS IOC Full replacement of the existing This control system will be easy adapted to the SPES Charge Breeder Plan for CB operation on Q1 2016 RJ45 SIEMENS PLC Vacuum devices EPICS CLIENT (GUI) F.O. Ethernet Switch RJ45 RJ45 Optic fiber F.O. Ethernet Switch EPICS IOC H.V. Platform Beam production & transport devices
The ECR EPICS IOC The new standard IOC developed at LNL has been adapted for this application A prototype is being used, which has: 32 analog inputs (16bits, 250ksps) 16 analog outputs (16 bits) 48 digital inputs 48 digital outputs 8 UART RS232 Later, the prototype will be replaced with the final version of the IOC; the software will remain unchanged Expansion boards Carrier board COM
The ECR Vacuum Control System Adapted to the new standard controller developed at LNL A prototype will be used initially for this application The IOC will communicate with the PLC using the PROFINET protocol for reading the status and sending commands Control Cabinet IOC Profinet Siemens PLC Vacuum system
ECR IOC Implementation Many instruments are controlled using analog signals with PID algorithms implemented on the IOC Other instruments are controlled through serial communication port using stream commands EPICS IOC 2AI, 2A0, 2DI, 2DO 2AI, 2A0, 2DI, 2DO 2AI, 2A0, 2DI, 2DO 2AI, 2A0, 1DI, 1DO 2AI, 2A0, 1DI, 1DO 1AI, 1A0, 1DO 1AI, 1A0, 1DO 1AI, 2DI, 1DO 1AI, RS232 RS232 RS232 RS232 2AI, 2A0, 1DI, 1DO 2AI, 2A0, 1DI, 1DO RS2 32 DIs RS232/RS485 F.O.

Beam Diagnostics New Control SW EPICS based Installation on the whole ALPI/PIAVE/Tandem complex completed. Reuse of legacy VME HW and new IOC s Ready for SPES HW
Magnets & Lenses PS Control EPICS based Prototype in commissioning since Nov. 2013 Daisy chain of six Danfysik PS + one steerer Deployment on new transfer line
New EPICS based magnet control SW on recently installed beam transfer Line for : Quadrupoles Dipoles Steerers Teslameters
Summary LLRF is progressing but still ~1 year of developments before mass production CB is far from being addressed, ECR control is a pale surrogate IT support for control is on track, we expect a benefit in a short time Concern about building infrastructure for controls on SPES, CB and new transfer lines
