1. Some quick news about X-Box1 data processing for BD location

2. Only “slow” data have yet been used (4 ns) Advantages: – good dynamic (log detector) – Previous pulses available for comparison Problem – Signal jitter (solved by cross correlation) – High requirement on edge detection time accuracy Calibration not yet applied

3. A hot cell around #4

4. But mainly due to clusters periods

5. Other days (4 March)

6. 5 March

7. RF signals and edge detection RF INC (blue) RF TRA resized (green) RF REF (red) Previous pulse (magenta) Zoom DC1 DC2

8. Signals BD precursor still exists on RF TRA

9. Signals with weak FCU

10. Jitter indicator Correlation with previous pulse (-1) (blue) Correlation with previous pulse (-2) (red)

11. Follow-up Use DC1 and DC2 times Use “fast” signals Use phase of “fast signals” Display others parameters (missing energy, time before BD…) Seek for correlations
