Since the vGATE-base is a unix operating system you</div> <div>should be able to type xclock and a small window with a clock</div> <div>should show up. It might also depend on the viewer, which </div> <div>you have to specify. I briefly checked the eMails concerning</div> <div>vGATE3.0 at it seems, that this is an issue. However, I have</div> <div>no own experience with vGATE3.0.</div> <div><br> </div> <div>Kind regards,</div> <div><br> </div> <div>Uwe<br> <div> <div style="color: rgb(0, 0, 0); letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;"> <div><span style="orphans: 2; widows: 2;">/----------------------------------------------------------------------</span></div> <div style="orphans: 2; widows: 2;">Prof. Dr. Uwe Pietrzyk<br> Diplom-Physiker<br> Institut für Neurowissenschaften und Medizin / INM-4<br> Forschungszentrum Jülich GmbH<br> 52425 Jülich<br> Tel: +49-2461-61 4763<br> Fax: +49-2461-61 2820<br> Mobil: +49-162-103-4871<br> eMail: <a href="mailto:U.Pietrzyk@fz-juelich.de">U.Pietrzyk@fz-juelich.de</a><br> <a href="http://www.fz-juelich.de/inm/inm-4/DE/Home/home_node.html">http://www.fz-juelich.de/inm/inm-4/DE/Home/home_node.html</a><br> &<br> Bergische Universität Wuppertal<br> Fakultät für Mathematik und Naturwissenschaften</div> <div style="orphans: 2; widows: 2;">Büro: D.08.01<br> Gaußstr. 20<br> 42097 Wuppertal<br> Tel: +49-(0)202-439-3523<br> Fax: +49-(0)202-439-2811<br> eMail: <a href="mailto:Uwe.Pietrzyk@physik.uni-wuppertal.de">Uwe.Pietrzyk@uni-wuppertal.de</a><br> <a href="http://www.medizinphysik.uni-wuppertal.de/">http://www.medizinphysik.uni-wuppertal.de</a><br> ----------------------------------------------------------------------/</div> </div> </div> <br> <div> <div>On 17 Nov 2015, at 14:58, Andrea González <<a href="mailto:andreita_5_92@hotmail.com">andreita_5_92@hotmail.com</a>> wrote:</div> <br class="Apple-interchange-newline"> <blockquote type="cite"><style></style> <div class="hmmessage"> <div dir="ltr">But when I run the simulation in my PC, I don't see the lines... <div>I will try with the EduGATE example.</div> <div><br> </div> <div>Thank you very much, I really appreciate your help.</div> <div>Very useful comments.</div> <div><br> </div> <div>Andrea.</div> <div><br> <br> <div> <hr id="stopSpelling"> From: <a href="mailto:u.pietrzyk@fz-juelich.de">u.pietrzyk@fz-juelich.de</a><br> To: <a href="mailto:andreita_5_92@hotmail.com">andreita_5_92@hotmail.com</a><br> CC: <a href="mailto:gate-users@lists.opengatecollaboration.org">gate-users@lists.opengatecollaboration.org</a><br> Subject: Re: [Gate-users] Best physics list for positron annihilation.<br> Date: Tue, 17 Nov 2015 13:39:05 +0000<br> <br> <div><br> </div> Dear Andrea, <div><br> </div> <div>there is nothing wrong with your macros and the findings can be</div> <div>explained by basic physics:</div> <div><br> </div> <div>you have placed a Na-22 source in the middle of a small cylinder</div> <div>with Rmax= 12mm and height of 6mm and PMMA as material.</div> <div>The cylinder is defined as detector.</div> <div><br> </div> <div>Starting the visualisation I can see:</div> <div>- blue lines, i.e. positively charged particles, obviously positrons whose</div> <div>energy was too high to be stopped in the PMMA.</div> <div><br> </div> <div>- green lines are the annihilation photons since only some of them are</div> <div>stopped in the very small cylinder but most of them can escape.</div> <div><br> </div> <div>Using ROOT to read the root-file, there is a simple means to check</div> <div>for all processes that happened (processName).</div> <div><br> </div> <div>To study the effect of the positron range and SEE the distribution of the</div> <div>emitted positrons before annihilation, we have prepared a special</div> <div>Module for EduGATE (all for free and found on the GATE homepage),</div> <div>called MR_PET, which besides showing the effect of charged particles</div> <div>in the magnetic field, can also be used (with the B-field being set to 0.0T)</div> <div>to study their spatial distribution.
