Dear all,

Please see the attached the corrected PPT.
and following are the papers and MAGBOLITZ simu data.
Don't hesitate to ask me if any more questions.
Best,

Code about the MAGBOLITZ sim: 

 double E_eff = E/1000*2/6/(gapWidth/10); //kV/cm
  alpha = getAlpha(E_eff); //mm^-1
  eta = getEta(E_eff); //mm^-1
  v_drift = getV(E_eff); //mm/ns
