<div dir="ltr">Gate users,<div><br></div><div>After much experimentation I believe I believe I have managed to solve the issue of having scintillation with an alpha source. I needed to include the proper physics needed for alpha particle interactions. I used the physics included in the hadrontherapyStandardPhys.mac in addition to Rayleigh scattering, Scintillation, and the optical physics processes. <br>
<br>Thank you very much to all who helped solve this problem.</div><div><br></div><div>-Amy</div></div><div class="gmail_extra"><br><br><div class="gmail_quote">On Mon, Jan 20, 2014 at 1:53 PM, Amy Meldrum <span dir="ltr"><<a href="mailto:ameldru@g.clemson.edu" target="_blank">ameldru@g.clemson.edu</a>></span> wrote:<br>

<div dir="ltr">Gate Users,<div><br></div><div>In an attempt to simplify my simulation to identify the problems, I am using VGate to model an alpha source, a plastic scintillator, and a PMT. However, when I run my simulation nothing happens; no optical photons are generated.</div>
<div><br></div><div>I use the OpticalSystem, and set my scintillator material to be a crystalSD. I have defined my surfaces and have the surface going from my scintillator to PMT set as perfect_apd (dielectric-metal). My alpha source is placed just above the scintillator. </div>
