Dear <span>Loïc</span>,
</p>
<p>
Thanks for your advice! It really helps to enhance my understanding about the TPS Pencil Beam Source from the link you provided. My confusion is that how to set the parameters in Source-Properties.txt file of TPS Pencil Beam Source, if I want to make the dose distributions in water consistent with the results from Pencil Beam Source setting.
</p>
<p>
In Pencil Beam Source simulation, the source position was located before the vacuum window and a water box was located at isocenter. The<span style="font-family:SimSun;"><span style="font-family:SimSun;" lang="de-DE"><span style="font-family:SimSun;" lang="en-US"> energy spread, spot size (x and y), divergence (theta and
phi), beam emittance(x-theta,y-phi) were set to 0.1% of the respective energy,3 mm,4 mrad and 15 mm·mrad. All beams are converging.</span></span></span>
</p>
<p>
<span style="font-family:SimSun;"><span style="font-family:SimSun;" lang="de-DE"><span style="font-family:SimSun;" lang="en-US">In TPS Pencil Beam Source simulation, "Nozzle exit to Isocenter distance" was set to the position of the vacuum window.</span></span></span>
</p>
<p>
<span style="font-family:SimSun;"><span style="font-family:SimSun;" lang="de-DE"><span style="font-family:SimSun;" lang="en-US">However, I find that the dose distributions with these two sources in water box were different, such as percentage depth dose (PDD).</span></span></span>
</p>
<p>
<span style="font-family:SimSun;"><span style="font-family:SimSun;" lang="de-DE"><span style="font-family:SimSun;" lang="en-US">Now, I doubt that my parameter settings in <span style="font-family:SimSun;"><span style="font-family:SimSun;" lang="de-DE"><span style="font-family:SimSun;" lang="en-US">TPS Pencil Beam Source simulation</span></span></span> might be wrong. How can I do?</span></span></span>
