1 Synchronization

After fixing the SPIDR configurations, the system started to work as expected.

2 First "Phase scan"

increased the delay in steps of 50ps.
Pulses: 40kHz, width: 60ns, acquisition time 10s.
~400 000 measurements per datapoint

Very sensitive for laser position and vibrations.

3 Same measurement three neighbouring pixels

Column 182 goes from count 2 to count 1 as expected
Column 181 goes from 0 to 15, gets assigned to next cycle
Column 183 goes from 1 to 15, it skips 0.

4 Next steps

• Make a code to automatise the phase scan.

• plan: create two sets of code one(PhaseScan) like SourceScan to record data store to one folder and another (PhaseAnalyser)
  ** PhaseScan: (experiment_name, delay, acquisition time) creates folder, acquires data,
  spot, evaluates the spot
  PhaseAnalyser: (experiment_name,col, row,) runs through all measurements in a folder and creates phase scan plots.
