uTCA / Stand-alone BPM
Beam Position Monitoring system
Our digital beam position monitoring system (BPM) based on uTCA technology provides an accurate measure of the beam position in the XY plane defined by the section of the accelerating cavities. It plays a crucial role in the commissioning and operation of the cavities that compose any particle accelerator. In addition to position, thanks to the BPM system it can be measured the spread and the current of the beam as well as the time of flight (TOF). Our solution is tailored to customer needs and takes full advantage of our previous expertise on PCIe-S BPM equipment now working with the most advance crate technologies.
Main performance highlights
- Dynamic range: [-75, 5] dBm
- Position precision < 15um RMS
- Phase precision < 0.1° RMS
- Position, phase and current alarms with response time < 1.9us.
- Position precision < 150um RMS.
- Phase precision < 0.8° RMS
Note: these performances are in worst case when receiving signals at -75dBm. Measured performed at 175MHz and 350MHz.
