EPICS Collaboration Meeting / BNL Kazuro Furukawa, KEK, 1

MicroTCA LLRF Controller w/ EPICS LLRF Controlers at KEK RF Group J-PARC CompactPCI-based DSP/FPGA system Communication to PLC-based Power supply controllers Since 2003 ILC and STF development Started with CompactPCI-based controller Based on J-PARC experiences Ten 16bit ADC, two 14bit DAC, Virtex2pro ATCA-based controller (being developed) For ILC “baseline” design Large card (14bit ADC x “32”, 16bit DAC x4, FPGA, etc) Reliability for large number of components Choice of bus was difficult VME was old No good standard was available for cPCI with PCIe EPICS Collaboration Meeting / BNL Kazuro Furukawa, KEK, 2

MicroTCA LLRF Controller w/ EPICS LLRF Controlers at KEK RF Group ATCA development in ILC collaboration DESY chose AMC cards on ATCA AMC Advanced Mezzanine Card cERL CW, under construction, for ERL nearer future AMC or MicroTCA-based LLRF Controller Future stability of 0.01% in amplitude, 0.01degree in phase For now, 0.1% in amplitude, 0.1degree in phase, 1 s loop delay SuperKEKB CW, under designing, starting part of construction Synergy between projects - MicroTCA STF/ILC for S1 global New RF system configuration , “DRFS” design ATCA MicroTCA EPICS Collaboration Meeting / BNL Kazuro Furukawa, KEK, 4

MicroTCA LLRF Controller w/ EPICS MicroTCA ( TCA) ATCA (2003) New computing standard for telecommunication and industry After CompactPCI (1993), for reliability with higher performance Many serial interconnects on backplane 2.5Gbps each (10Gbps in the future) »One card covers all phones in a small city with a certain implementation IPMI surveillance/remote-management for reliability AMC (Advanced Mezzanine Card for ATCA) Serial interconnects, IPMI, good part of ATCA Like IP-module to VME, PMC to cPCI MicroTCA (2008) AMC card itself is powerful Direct slot-in AMC cards in a Box Commercial I/O cards for industry are available EPICS Collaboration Meeting / BNL Kazuro Furukawa, KEK, 5

MicroTCA LLRF Controller w/ EPICS Accelerator Controls VME Unix (1990 ) Standard EPICS configuration With many third layer field networks Every controller on network (1993 ) Single layer in physical, two layer in logical Every controller with EPICS IOC (2005 ) Channel Access everywhere For longer term maintenance EPICS Collaboration Meeting / BNL Kazuro Furukawa, KEK, 6

MicroTCA LLRF Controller w/ EPICS Let’s employ Channel Access on TCA Backplane ! Let’s embed EPICS IOC on to Each TCA/AMC Card ! Miura and Furukawa EPICS Collaboration Meeting / BNL Kazuro Furukawa, KEK, 9

MicroTCA LLRF Controller w/ EPICS IOC on MicroTCA Natural to put IOC on TCA LLRF Controller And on ATCA LLRF Controller Chose GbEthernet as a main media on the backplane interconnect Somewhat unique Some other institutes chose PCIe as the media Chose PowerPC core on Virtex5 ML507 of Xilinx as a good reference Linux on PowerPC No realtime processing is necessary In the future, we may use realtime ( 100 s) feature of Linux EPICS Collaboration Meeting / BNL Kazuro Furukawa, KEK, 10

MicroTCA LLRF Controller w/ EPICS RF Group MicroTCA based LLRF Controller Single-width full-height module Without physics experiment extension (we started earlier) Front-panel connectors (rather busy) Digital part and Analog part are separate ADC 16bit, 130Msps, x4 DAC 16bit, 500Msps, x4 Virtex5 with PPC440 RAM 640MB, Flash 64MB Also monitor card with the same digital part ADC 14bit, 400Msps, 1.4GHz, x2 Fabrication subcontracted Mitsubishi Electric Tokki System Windriver Linux (ML507 is supported) EPICS Collaboration Meeting / BNL Kazuro Furukawa, KEK, 11

MicroTCA LLRF Controller w/ EPICS EPICS IOC on MicroTCA LLRF Controller Linux 2.6 on Virtex5 Boot from Flash EPICS from NFS, or from Flash Slight difficulties because Lack or experiences Difference (memory size etc.) between ML507 and the real card Relatively straight forward EPICS 3.14.9 for now Driver to FPGA (with mmap) Scalar values directly, and waveforms through ringbuffer Channel access on backplane interconnect Directly connected to outside at first Possible to install gateway at local CPU if necessary EPICS Collaboration Meeting / BNL Kazuro Furukawa, KEK, 13

MicroTCA LLRF Controller w/ EPICS Slow control with PLC Embedded IOC MPS with FPGA/PPC Embedded IOC EPICS Collaboration Meeting / BNL Kazuro Furukawa, KEK,

MicroTCA LLRF Controller w/ EPICS RF Group Under Evaluation Preliminary I/Q control stability results Much better than the specification 0.022% in amplitude, 0.016degree in phase EPICS Collaboration Meeting / BNL Kazuro Furukawa, KEK, 15

MicroTCA LLRF Controller w/ EPICS More development FPGA controller is ready (Sep.2010) EPICS IOC and local display application With EDM under development TCA management capabilities over IPMI Commissioning in 2011 for STF and cERL Slightly later for SuperKEKB Future Comparison to ATCA Move out of Windriver Linux (?) Redundant System (?) EPICS Collaboration Meeting / BNL Kazuro Furukawa, KEK, 16

MicroTCA LLRF Controller w/ EPICS Conclusion Collaboration between RF group, Mitsubishi Elec. Tokki System, and Control group went well All components embed EPICS IOC TCA FPGA controller, PLC controller, MPS controller Performance test was acceptable Showed TCA capability Controls Have Interface to Every System We can Enjoy Accelerators With Phronesis (Ability to understand the Universal Truth) EPICS Collaboration Meeting / BNL Kazuro Furukawa, KEK, 17
