Going for ATCAGoing for ATCA
ATCA platform is gaining traction in the physics community because of
• Advanced communication architecture supporting Ethernet, InfiniBand, StarFabric, PCI Express, Serial RapidIO …
• Scalable aggregated shelf capacity to 2.5Tb/s
• Scalable system availability to 99.999%
• Robust power infrastructure (distributed 48V power system) and large cooling capacity (200W per board)
• Reliable mechanics (serviceability, shock and vibration)
• Full redundancy support with hardware management interface
First commercial open standard designed for
– high throughput
– High availability
High interest to data acquisition for physics and attractive for
experiments requiring a very high up-time

Leveraging on modularityLeveraging on modularityChopped integrator for long duration pulsesChopped integrator for long duration pulses
Lower drift than normal analog integrators (suited for long pulse experiments)
Magnetics signals converted into AC signal by analog switch and numerical integration in PC or FPGA.
Conversion into AC signal cancels drift caused by operational amplifiers (present in normal integrators)
Since integration is numerical, module will additionally provide unintegrated signals (for fluctuation analysis)

ATCA key advantages have been successfully demonstrated:• real-time data processing, e.g. JET, COMPASS, TCA-Br
• MIMO fast control applications, e.g. JET
ATCA is being considered for critical fast plasma control systems, e.g. ITER, W7-X
• Modularity• High availability• Reliability• Channel density per board
IPFN is looking forward to work on an ATCA based system for update of RFX feedback control
