Forums, postings and threads

Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.

Layout of the posting thread(s)

The posting threads can be shown with/without the text of the postings ("Inline depth"). In addition the depth of the thread can be controlled ("Outline depth"). For both cases several values are provided, which can be toggled. Note that the displayed values are those, which can be chosen, they do not correspond to the actual display status of the thread(s).

The authors of any ancestor posting (if they have not unsubscribed)

Some browsers display old pages from the cache

Some browsers (e.g. Firefox) display a page from the cache even though the page has been updated. As a result, one may not get the latest messages in the forum's outline or the logon ID of the previous session appears on the upper right corner. If one suspects that he or she does not get the latest content of a page, try clearing up the personal data from the browser's cache as the following:

Tools -> Clear Private Data -> Clear Private Data (from browser Firefox)

Tools -> Delete Private Data (from browser Opera)

then reflesh the current page to get the latest content.

Details on "Inline depth" and "Outline depth"

Threads and the follow-up messages are numbered. There is one line per posting, normally starting with the posting number. The URLs of a posting and its responses reflect the depth of the follow-up postings. Watch the URLs to see how this is done. Depending on the chosen display options, the thread-display may be incomplete; the number of messages at the next level is, however, displayed, e.g. "…3 message(s)". You may not see all contributors unless you choose "All".

Messages are "chained" if there are only replies at the first level, i.e. 1/1.html, 1/1/1.html etc. In case of "chained" messages the message number is replaced by the icon and there is no indentation.

Inline: Display the subject line only or also the text of the posting(s); for the choice "All" the "Outline" choices are switched off.

about inelastic models in Geant4

Hello,

I know that Binary Light Ion Cascade Model for inelastic scattering can't be applied to generic ions with A>12, unless the material in which they travel has A<13. And also G4wilsonAbrasionModel can't be applied to generic İon if they have energies < 70MeV/n.

I use Ar ions (A=40 for Ar) with energy 20MeV/n as a projectile, and silicon material (A=28 for silicon) as a target in simulation. I can't use both Binary Light Ion Cascade Model and G4wilsonAbrasionModelthese in such a case.

Could you tell me what can i do, please?

any comments are appreciated,

best regards,

adnan.

Re: Re: about inelastic models in Geant4 (Vladimir Ivanchenko)

First i want to thank you for your answer.
As you said, i used BinaryLightIon model for inelastic interactions in simulation. if i use thicknes of 1.5mm silicon material , never interaction occur for Ar ions with energy 20 MeV/n. However, if i use thicknes of 5 cm silicon material,some fragmentations appear.
for 1.5mm Si thicknes and 20 MeV/n Ar ions
