Dear experts Good afternoon. Can you explain to me what went wrong? I want to generate a SOBP, set by their own energy and weight, here is a screenshot of the error SOBP.dat (598 Bytes) sourceSpectrum.f (8.6 KB) [问题一] I sincerely look forward to your early answer, I wish you a happy work, happ…

Hi, Your request is a bit unclear. Nevertheless, I tried to understand what you needed. I assume you want to sample from a discrete spectrum some protons to study the spread-out Bragg peak. Your code is not compiling, there are several syntax errors. Then you want to calculate the cumulative distr…

Dear Daniele Calzolari Good evening! Thank you very much for taking time out of your busy schedule to help me answer my questions. I have successfully compiled and run your file! Your files produced SOBP perfectly today, just as I set multiple SPOTBEAM effects! However, I have a very confused prob…

Hello Zhuhuaiyu, The source routine I provided you manages just the particles energy spectrum. If you want to add the beam size, you need to sample it, and add it to the particle coordinates (see also this discussion: Beam sizes when using source.f ). If you want to proceed with this source routin…

Dear Daniele Calzolari Good evening. In these three days, I have rewritten the document according to your methods, and after many attempts to get the results (for protons only), now I would like to ask you about the following three questions: First, I am not sure if I wrote it right, and I always …

You are not sampling correctly. When you’re doing the sampling, you are doing this: XLOW = -3.5D0 * SQRT( FLRNDM(XDUMMY) ) XHIGH = 3.5D0 * SQRT( FLRNDM(XDUMMY) ) YLOW = -3.5D0 * SQRT( FLRNDM(XDUMMY) ) YHIGH = 3.5D0 * SQRT( FLRNDM(XDUMMY) ) The x and y limits should not be …
