Principles of Application
Bragg-Peak• Well defined point at which
beam deposits energy• Carbon-Ions have direct
physical effect on tumor cell
PR-111003-a-JGU, October 9th, 2011
Pencil Beam Scanning• Precise deposition of dose• Reduce irradiation time• Improve dose homogeneity• Treat problematic tumors
J. Gutleber6
MedAustron / CERN
• CERN designs accelerator and the accelerator control system• MedAustron employees stay at CERN since October 2009• A framework agreement with Cosylab was established in April 2010• Department BE hosts the project (BE/OP-MED section)
• Agreements with departments• Various agreements with EN and BE for support on technologies used
has been established with BE-OP
• MedAustron PXI users at CERN• 1 person in control system project (Cesar Torcato de Matos)• 1 person in beam diagnostics project (Anton Kerschbaum)• 2 more possibly to come throughout the year for the injector test
stand in building 184.

Developments
• Front End Controller Operating System (FECOS)• Main timing system• Power Converter Controller• Beam Diagnostics and Instrumentation• Injector LLRF integration (TINE protocol)• Ion Source integration
PR-111003-a-JGU, October 9th, 2011

FECOS• Object oriented LabView (Real-Time) framework• Uniform and transparent network communication
• WinCC OA integration through OPC/SV server• MedAustron Publisher/Subscriber (MAPS) for high rate data exchange
based on NI Simple TCP Messaging (STM)
• Uniform operation (state machine)• Configuration• Real-time tasks, error handling, remote logging• Runs in tier 3 (equipment tier)

Main Timing System (REDNet)
• Real-Time Event Distribution Network (REDNet)• Based on Micro Research Finland (MRF) hardware layer
• PXI running, PXIe event receiver cards under development• Drivers and libraries for LV and LV-RT developed
• Event broadcast sequencer• General-purpose “cycle sequence-player” system
• Symmetricom S350 GPS integrated for 100 ns timestamps,1 µsec event granularity10 nsec granularity for synchronizing 2 injection devices
• 50 receivers needed (but scales to several hundreds)• Implemented by Cosylab• In-device response via RT bus or Universal IO modules

Power Converter Controller
PR-111003-a-JGU, October 9th, 2011
FlexRIO adapters (6 optical SFPs)
RT link(100 kHz)
FPGA-based FED
• All 262 power convertersoperated via NI-FlexRIO based distributed system• High density 8-16 FlexRIOs in 1 chassis (around 70 PCOs per chassis)
• Power converters are • RS-422 serial devices for slow controls
(uniformed interface design for all power converters)• Voltage sources driven via in-house built regulation board (DSP)• Special magnets with optical trigger for setpoints via RS-422

Transition from PXI to PXIe
• Currently evaluating with NI best configurations• MRF develops with Cosylab a PXIe event receiver card
• Prototype in december, final product in May 2012
• Evaluation before EoY Windows (8 GB) vs. LV-RT (4 GB)• For all applications except beam diagnostics

Wish List - Brainstorm
• Shared variable engine performance evaluations and tuning• Maybe common project on publisher/subscriber?
• DIM usage failed due to problems on LV-RT
• Hypervisor evaluation• Tuning of application’s memory tuning• Are you interested in REDNet?• Are you interested in FECOS?
