<p>Hi everyone, <br>
</p>
<p><br>
</p>
<p>I am facing a problem concerning the physics settings. I would like to use the physics list
<span>QGSP_BIC_EMZ but change the step function for electron <span>ionisation <span>
(dRoverRange and finalRange)</span></span>. <span>Is there anyone who has done this before or knows how I can do this in Gate?
</span><br>
</span></p>
<p><span><br>
</span></p>
<p><span>I tried to do this via the commands: <br>
</span></p>
<p><span><span>/gate/physics/addPhysicsList QGSP_BIC_EMZ</span></span></p>
<p><span><span>/gate/physics/processes/ElectronIonisation/setStepFunction e- 0.05 0.1 mm</span></span></p>
<p><span><span></span></span><br>
</p>
<p>Unfortunately this did not work<span></span>, since my simulation output was: <br>
</p>
<p></p>
<div>eIoni: for e- SubType= 2<br>
dE/dx and range tables from 100 eV to 10 TeV in 220 bins<br>
Lambda tables from threshold to 10 TeV, 20 bins per decade, spline: 1<br>
<b>finalRange(mm)= 0.01, dRoverRange= 0.2</b>, integral: 1, fluct: 1, linLossLimit= 0.01<br>
===== EM models for the G4Region DefaultRegionForTheWorld ======<br>
PenIoni : Emin= 0 eV Emax= 1 MeV<br>
MollerBhabha : Emin= 1 MeV Emax= 10 TeV deltaVI</div>
<br>
<p></p>
<p>I also tried to build my own physics list by adding all processes used in <span>
QGSP_BIC_EMZ</span> and then setting the step function but I was not able to specify the physics models<span><span> needed</span></span>.</p>
<p><br>
</p>
<p>Best regards, <br>
