Sorry, I mean the number for showing both material name and cell number at once, because with gshow=2 we only get material name and gshow=3 only for the region number. 21:31:52 発信元: 125 maheraj khan : Replying to "Dr.@*Tutor* Yusuke M..." Thank you @*Tutor* Yusuke Matsuya Sensei. Obviously I'll do. 21:32:16 発信元: 096 Assen Kirov : Does the order of parameters in the source matter ? 21:32:31 発信元: 125 maheraj khan : Reacted to "Of course. OK! Pleas..." with ❤️ 21:32:35 発信元: 155 Ahadi Damar Prasetya : Reacted to "gshow=2 will be with..." with 👍 21:32:49 発信元: *Tutor* Tatsuhiko Ogawa : Replying to "Are these photons ?" projectile is carbon-12 ion 21:32:57 発信元: *Tutor* Takuya Furuta : Replying to "Is there any option ..." There is no option to show both. It will be messy. So please create two tallies with same setting but different gshow. 21:33:09 発信元: *Tutor* Seiki Ohnishi : Replying to "Does the order of pa..." That dose not matter. 21:33:32 発信元: 183 Bayu Ahmad Fauzan : Reacted to "Of course. OK! Pleas..." with ❤️ 21:33:33 発信元: 183 Bayu Ahmad Fauzan : Removed a ❤️ reaction from "Of course. OK! Pleas..." 21:35:27 発信元: 183 Bayu Ahmad Fauzan : Replying to "how do we define a c..." thank you. 21:35:41 発信元: 119 A.F.Jundi Main : Does increasing the number of particle or adding another batch can reduce the error in error file? 21:36:19 発信元: *Tutor* Takuya Furuta : Replying to "Does increasing the ..." Yes. You will come to that in the following this lecture. 21:36:24 発信元: 178 A.J.Puspitasari : Replying to "can we get the 3D ou..." Ok I'll wait for it. Thank you! 21:36:47 発信元: *Tutor* Takuya Furuta : I was wrong.

The resolution is controlled by the nx, ny, and nz. But be careful that the statistics get worse when you choose smaller box because the number of particles come to that box reduces by finer resolution. 21:47:37 発信元: 096 Assen Kirov : Replying to "Does the order of pa..." So these are all trajectories scored in 1 Y bin ? 21:48:21 発信元: *Tutor* Takuya Furuta : Replying to "Does the order of pa..." Yes, for this example. 21:48:31 発信元: 119 A.F.Jundi Main : Reacted to "Yes. The resolution ..." with 👍 21:55:21 発信元: 096 Assen Kirov : if more than 1 y bin, what will be displayed ? 21:55:45 発信元: *Tutor* Takuya Furuta : It will come with more than 1 pages. 21:56:48 発信元: 096 Assen Kirov : 2x5 time points =10 pages ? 21:57:40 発信元: *Tutor* Takuya Furuta : If ny=2 and nt=5, yes. 22:04:28 発信元: 003M.Tzivaki : for the management of time is it assumed that all particles are emmitted at the same time? 22:05:43 発信元: *Tutor* Takuya Furuta : Replying to "for the management o..." Yes, The time start is the incidents of the radiation starts. 22:07:18 発信元: 003M.Tzivaki : Antworten an "for the management..." does this mean there is an option to have a continuous source that has a time dependency? 22:07:25 発信元: 003M.Tzivaki : Hat auf "Yes, The time star..." mit 👍 reagiert 22:09:15 発信元: 097 Evan Lambert : Hello, I have gotten stuck on the step where we increase the mesh points in x and z. I cannot seem to get the expanded mesh points on the EPS file although my computational time has increased. I 22:09:44 発信元: *Tutor* Seiki Ohnishi : Replying to "for the management o..." Yes it does. t-type subsection is used to describe time dependency. 22:10:49 発信元: *Tutor* Tatsuhiko Ogawa : Replying to "Hello, I have gotten..." Shall we talk in a breakout session? 22:11:03 発信元: 097 Evan Lambert : Replying to "Hello, I have gotten..." Yes please! 22:12:01 発信元: 003M.Tzivaki : Antworten an "for the management..." oh this is very cool! Can this be coupled with a source that changes its geometry and/or intensity? (I am thinking radiation therapy machines) 22:12:16 発信元: 003M.Tzivaki : Hat auf "Yes it does. t-typ..." mit 👍 reagiert 22:13:02 発信元: *Tutor* Takuya Furuta : Replying to "for the management o..." Unfortunately change of the geometry in time is not possible in simple way in PHITS. 22:13:41 発信元: *Tutor* Takuya Furuta : Replying to "for the management o..." So you just need to calculate in snap shot base and take a weighted average. 22:13:42 発信元: Khelifi Rachid : how we can defind an ions particle 22:14:46 発信元: *Tutor* Takuya Furuta : Replying to "how we can defind an..." For carbon-12, part = 12C. 22:14:49 発信元: *Tutor* Yuho Hirata : Replying to "how we can defind an..." Mass number+symbol 22:15:09 発信元: 003M.Tzivaki : Antworten an "for the management..." ah that would have been too good to be true, still continuous sources are already quite interesting. Can the spectrum be changed with time? 22:15:40 発信元: 003M.Tzivaki : Hat auf "So you just need t..." mit 👍 reagiert 22:15:47 発信元: Khelifi Rachid : Reacted to "Mass number+symbol" with 👍 22:15:57 発信元: Khelifi Rachid : thanks 22:18:27 発信元: Khelifi Rachid : If we are interested in energy loss in different kinds of targets, how can we get an output file with MeV/cm unit 22:18:32 発信元: *Tutor* Seiki Ohnishi : Replying to "for the management o..." I'm sorryt the energy and time cannot be dependent. 22:18:37 発信元: 096 Assen Kirov : for t-type=2, nt=1, tmin,max do not matter ? 22:19:09 発信元: 003M.Tzivaki : Hat auf "I'm sorryt the ene..." mit 👍 reagiert 22:20:06 発信元: *Tutor* Yusuke Matsuya : Replying to "If we are interested..." If you would like to calculate LET (stopping power), you can use [t-LET] tally. 22:20:54 発信元: *Tutor* Takuya Furuta : Replying to "for t-type=2, nt=1, ..." It matters. The results for that time interval will be shown. 22:20:57 発信元: 226 D.Posthuma de Boer Main : If I set part = electron I get no tracks at all. 22:20:58 発信元: *Tutor* Tatsuhiko Ogawa : Replying to "If we are interested..." Alternatively, if you just want to know stopping power, another code SRIM http://www.srim.org/ is much easier and simpler. 22:21:19 発信元: 003M.Tzivaki : Antworten an "for the management..." ah thank you for the answers. So one has to be careful when having a time dependent source, to make sure that the tallies extend far enough into time to capture all the incoming particles, right? 22:21:51 発信元: *Tutor* Tatsuhiko Ogawa : Replying to "If I set part = elec..." please put "negs = 1" in [parameters] section. This is one of the contents of basic lecture 3. 22:21:58 発信元: Khelifi Rachid : Reacted to "If you would like ..." with 👍 22:22:14 発信元: *Tutor* Tatsuhiko Ogawa : Reacted to "If you would like to..." with 👍 22:22:41 発信元: 003M.Tzivaki : Antworten an "for the management..." what would be an example application for this functionality? 22:23:19 発信元: *Tutor* Takuya Furuta : Replying to "If I set part = elec..." The electrons are not transported in the default setting. To activate electron transport you need to specify negs=1 as Ogawa-san said. 22:25:26 発信元: *Tutor* Tatsuhiko Ogawa : Reacted to "The electrons are no..." with 👍 22:25:48 発信元: 100-Le Huu Loi-Main : Reacted to "The electrons are no..." with 👍 22:25:52 発信元: 100-Le Huu Loi-Main : Reacted to "please put "negs = ..." with 👍 22:29:02 発信元: *Tutor* Takuya Furuta : Replying to "for the management o..." For example, someone wants to know the time profile of delayed neutrons for source with time profile. 22:29:12 発信元: *Tutor* Seiki Ohnishi : Replying to "for the management o..." Yes it is. But if you don't make time-bin (time-group defined by t-type in t-cross) t=0 to infinity is scored. 22:29:19 発信元: 003M.Tzivaki : Hat auf "Yes it is. But if ..." mit 👍 reagiert 22:29:33 発信元: 003M.Tzivaki : Hat auf "For example, someo..." mit 👍 reagiert 22:29:56 発信元: 003M.Tzivaki : Antworten an "for the management..." ah excellent, makes total sense, thank you again 22:30:27 発信元: 132_K.Skerratt-Love_Main : my eps file is blank, figure does not have plotted flux of particles 22:31:09 発信元: *Tutor* Tatsuhiko Ogawa : Replying to "my eps file is blank..." Shall we discuss in a break out session? 22:31:15 発信元: 132_K.Skerratt-Love_Main : yes please 22:31:24 発信元: 068 ahid nurmanjaya : Replying to "my eps file is blank..." I got blank too 22:34:12 発信元: *Tutor* Takuya Furuta : Replying to "for the management o..." By the way, the setting for the time profile source is given in Sec. 5.3.21 of the PHITS manual (phits/manual/manualE-phits.pdf) . 22:34:33 発信元: *Tutor* SHIGYO Nobuhiro : Replying to "my eps file is blank..." @068 ahid nurmanjaya Would you like to have a breakout room? 22:34:45 発信元: 180 M Septyawan Aulia : mine was blank also but my sloppy hand just wrote ne = 1. I changed to 100 and it OK now 22:34:45 発信元: *Tutor* Takuya Furuta : Replying to "for the management o..." Please have a look later. 22:35:39 発信元: 155 Ahadi Damar Prasetya : Reacted to "mine was blank but m..." with 👍 22:36:43 発信元: 068 ahid nurmanjaya : Replying to "my eps file is blank..." I found the culprit, thank you all, I changed the ne from 1 to 5 then 100 22:37:12 発信元: 180 M Septyawan Aulia : Reacted to "I found the culprit,..." with 👍 22:37:17 発信元: *Tutor* Tatsuhiko Ogawa : Reacted to "I found the culprit,..." with 👍 22:37:33 発信元: *Tutor* SHIGYO Nobuhiro : Reacted to "I found the culprit,..." with 👍 22:40:20 発信元: 003M.Tzivaki : how are bin boundaries handled in phits? Both for energy bins and for location bins 22:40:24 発信元: 079 Sujoy Chatterjee : Is the default y axis in logarithmscale ? 22:40:26 発信元: 131 A.HUGUES : why unit = 12 ? Could we have guess before running the exercice ? 22:42:04 発信元: 185.W Asztalos : Replying to "why unit = 12 ? Coul..." I'm not an instructor, but I think it's because it's carbon 12 and in the case described it would be MeV/u 22:42:27 発信元: *Tutor* Tatsuhiko Ogawa : Reacted to "I'm not an instructo..." with 👏 22:42:30 発信元: *Tutor* Takuya Furuta : Yes, it is. You can change by setting a parameter (angel=ylin) to make it linear. You will come to that later in this lecture. 22:42:33 発信元: *Tutor* Yuho Hirata : Reacted to "I'm not an instructo..." with 👍 22:42:40 発信元: 131 A.HUGUES : Replying to "why unit = 12 ? Coul..." Thanks I was not sure 22:43:46 発信元: 096 Assen Kirov : e0 = [MeV/u] by default per lec02.inp ? 22:45:00 発信元: 096 Assen Kirov : oh, yes, the iMeVperU is for emax emin only ? 22:45:45 発信元: 079 Sujoy Chatterjee : Replying to "Is the default y axi..." Thank you 22:45:46 発信元: *Tutor* Takuya Furuta : Replying to "Is the default y axi..." I was not correct. There is some explanation how to use "angel" parameter but not angel=ylin to make the y-axis to be linear. 22:46:14 発信元: 079 Sujoy Chatterjee : Replying to "Is the default y axi..." Okay 22:46:36 発信元: 205 Zahidul Islam Apu Main : What's the advantage of histogram plot compare to line plot? 22:46:46 発信元: *Tutor* Seiki Ohnishi : Replying to "oh, yes, the iMeVper..." e0 is also MeV/u. 22:47:03 発信元: *Tutor* Takuya Furuta : Replying to "oh, yes, the iMeVper..." Yes. The source energy is always given by MeV/u. 22:48:59 発信元: *Tutor* Seiki Ohnishi : Replying to "What's the advantage..." The histgram is more precise expression because the dsitribution inside a group is unkonw or integrated over a group. Moreover histgram is easy to understand the group structure, the group boundaries and widths. 22:50:01 発信元: 205 Zahidul Islam Apu Main : Replying to "What's the advantage..." @*Tutor* Seiki Ohnishi okay I get it, thank you 22:51:58 発信元: 003M.Tzivaki : Antworten an "oh, yes, the iMeVp..." just to clarify, this is the case only when using ions right? 22:52:10 発信元: *Tutor* Takuya Furuta : Replying to "oh, yes, the iMeVper..." Yes. 22:52:22 発信元: 003M.Tzivaki : Hat auf "Yes." mit 👍 reagiert 23:01:23 発信元: 220 Yusuf Efe Zorlu : See you later 23:01:29 発信元: 003M.Tzivaki : how are bin boundaries handled in phits?

The bin boundaries are created by x-type submesh. The eneryg group structures are defined by e-type submesh, and location is [xyz]-type. 23:03:42 発信元: 165 Rafah Alotaibi : thank you 23:03:45 発信元: *Tutor* Takuya Furuta : It only becomes a problem for the exact incidence, energy and location. But the values are continuous "real number" so there is no problem in practice. 23:03:49 発信元: 066 Serge Takoukam : Thank you very much, see you tomorrow 23:03:50 発信元: 068 ahid nurmanjaya : Good night sensei it is 11.00 p.m
