<div dir="ltr">Hello GATE Users,<div><br></div><div>I am building my first simulation while reading through the User's Guide but am confused about source definitions when it comes to simulating a scintillator.</div><div>
<br></div><div>Basically I am trying to model the propagation of optical photons as a result of a plastic scintillator being irradiated with an alpha or beta source. When reading through 'Users Guide V6.2: Generating and Tracking Optical Photons,' it says to add the source as an optical photon source as:</div>
<div><br></div><div>/gate/source/addSource OPsource gps</div><div>/gate/source/OPsource/gps/particle optical photon</div><div>(and so on...)</div><div><br></div><div>Does this mean that the only way for optical photons to be generated is by simply starting them inside my scintillator? Is it possible for me to define my other (alpha or beta) source, and then have the optical photons be generated once the alpha/beta partcile interacts with the scintillator? </div>
<div><br></div><div>I appreciate all the help while I am getting acquainted with GATE.</div><div><br></div><div><br></div><div>-Amy</div></div>
