• Simultaneous acquisition of ADC raw, Turn-by-Turn (TBT), Fast Acquisition (FA), and Slow Acquisition (SA) data

• Excellent beam current independence and channel isolation

• Support for pulsed, first-turn, turn-by-turn, and closed-orbit measurements

• Up to four BPM processing modules in a single 2U chassis

• Latest Xilinx Kintex UltraScale+ FPGA technology

• Open architecture supporting user-developed applications

• Native support for EPICS, TANGO, HTTP, MATLAB, and other control systems

• Scalable platform for machine diagnostics and feedback applications

Benefits

Accelerator Commissioning

Provides comprehensive beam diagnostics for rapid machine commissioning and optimization.

Machine Physics Studies

Enables detailed investigation of beam dynamics using raw ADC data, first-turn analysis, and turn-by-turn measurements.

High-Performance Orbit Measurement

Delivers highly stable orbit measurements with exceptional resolution across multiple acquisition rates.

Future-Proof Architecture

Modular MTCA.0 platform with expansion capability for Fast Orbit Feedback (FOFB) and additional processing modules.

Signal Processing Architecture

Input signals from four BPM electrodes are processed through a sophisticated signal chain consisting of:

1. Analog front-end conditioning

2. High-speed 16-bit ADC digitization

3. FPGA-based digital signal processing

4. Time-domain and frequency-domain analysis

Signals are sampled at PLL-controlled frequencies between 100 and 125 MHz. Raw ADC data is buffered and processed through:

• Time Domain Processing (TDP)

• Digital Down Conversion (DDC)

• I/Q Demodulation

• Turn-by-Turn Processing

• Fast Acquisition Processing

• Slow Acquisition Processing

The processing chain allows users to simultaneously access all major data streams, providing complete visibility into beam behavior.

Data Acquisition Modes

Raw ADC Data

Provides access to unprocessed beam signals for advanced diagnostics and machine studies.

Turn-by-Turn (TBT)

High-resolution beam position measurements synchronized to accelerator turns.

Fast Acquisition (FA)

Supports fast orbit monitoring and feedback systems.

Slow Acquisition (SA)

Provides highly stable orbit measurements for routine machine operation.
