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.
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.
|1||0||1||no text / full text of posting|
|2||1||All||text for level 1 only / text for All postings|
Outline: Choose the depth of the posting thread, successive toggle controls provide increasing detail.
|1||2||1||2 levels / 1 level (original posting)|
|2||3||2||3 levels / 2 levels|
|3||3||All||3 levels / all levels (all postings)|

Dear user, in order to calculate the let you can utilize the method ComputeTotalDEDX(...) (see the G4EmCalculator class). This give you directly the total (nuclear+electronic) stopping power at a given energy/particle/material. Starting from this data you can easily get the Let (clearly this depends by the many definitions of the linear energy transfer).
An Hadrontherapy version with the possibility to calculate LET for any particle will be soon published. Regards, Pablo Cirrone
