I have to try several times to make the electron source to hit the anode(tungsten) to get photons but the electrons are not hitting the anode for me to get photons. I do not know if what am doing is wrong or am missing something. Please find attached script on the beam description and the source description. Please, I need help and is there any script on such type of simulation to adopt and modify. Thanks in advance.</p> <p>Best regards,</p> <p>Emmanuel Marfo</p> <p>(STUDENT)</p> <p>University of Otago</p> <p>Christchurch-New Zealand</p> </div> </body> </html>
