Application notes

Special features and applications using pyBAR are listed here. The corresponding code is in the [example folder](https://github.com/SiLab-Bonn/pyBAR/tree/development/examples).

Charge reconstruction: Threshold-Method
Content:

  • Shows a charge reconstruction method to get single pixel charge spectra
  • Shifts the threshold while measuring the particle rate to record the integrated charge spectrum
  • Noise < 200 e
  • statistical method, no single hit charge
  • Paper

Use
 

 

Charge reconstruction: TDC-Method
 

 

Primlist: Measure Signal-to-Noise for the TOT-Signal using the TDC-Method
Content:

  • Shows how to use write a prim list
  • Chip parameters are changed within a loop
  • Results are analyzed and plotted within the same script

A prim list ([prim_list_tdc_sn.py](https://github.com/SiLab-Bonn/pyBAR/wiki/) is used to change the parameters that change the signal-to-noise of the TOT-Signal: discriminator bias, feedback current and threshold (DisVbn, PrmpVbpf, Vthin_AF). One can see that low threshold / low feedback / high discriminator bias tunings give a better S/N.
