Performance
| @~300 kHz revolution frequency | |
|---|---|
| Turn-by-turn resolution | 0.35 µm |
| Fast data resolution (10 kHz rate) | 0.07 µm |
| Beam current dependence | 0.5 µm |
| Crosstalk between channels | better than -50 dB |
Beam Current Dependence Comparison
Typical position variation: around 1 μm down to -80 dBm input signal
level at centered beam and down to -60 dBm input signal level at
off-centered beam position (~600 μm).
Machine Physics Studies
The raw wideband Analog to Digital Converter (ADC) data buffer allows detailed analysis of fast phenomena that last up to several milliseconds. The newly introduced turn-by-turn calculation method, called Time Domain Processing (TDP), is intended for short fill or single bunch fill patterns. The RMS on the turn-by-turn data is improved by factor of 4-5 compared to classic Digital Down Converter (DDC) calculation method.
