beam loss monitor

My parts:

• test bench setup
• automatic test program (python)
• post-data processing (python)
• softioc program (C++)

• Test bench for beam loss monitor

   

• 6ch waveform retrieve (keysight oscilloscope control, qt5+python+qcodes)

  

• frequency sweeping (tek function generator control, qt5+python+qcodes)

  

• softioc (running on zynq7015, C++ version)

  - publish PVs (counts, interlock, ADC raw data...) - calibration (ADC readout) - autosave (save key parameters)

• diagrams showcase (jupyter notebook)

cfc test equipment (128ch)

we need an equipment for 128 Channel Charge Integrator which can route our current (pA) signal to it one by one.


My parts:

• test equipment develop
  • fpga program (verilog)
  • softioc program (python)
  • hardware design (designed with kicad, manufactured by JLC PCB)
• keithley current source control (python)
• automatic test program (jupyter notbook)
• data processing (python data retrieve, diagram plotting)

• test equipment

  • first version (not my hardware design but I developed its FPGA program. There're so many HW bugs, even relays are all flipped, fixed by hand...🙄)

  

  • second version (basically the same with first version with HW issues fixed but still inconvenient, can only switch channels in order)
  
  • third version (use raspberry pi SBC with a 128ch io-expander hat, python+softioc inside, easy to use, fully designed by myself)

  

• keithley current source control (softioc based on pcaspy with phoebus opi)

  

• diagrams showcase (jupyter notebook)

Magnet Test

My parts:

• data processing (python data retrieve, render to html)
