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.

Hi, I found out that I have the possibility to compare the flux (binned into 15 energy bins) in the small measuring voxel with calculations performed with MCNP (results were used to calculate the ambient dose equivalent published in the ICRU 57 report).
Unfortunately, my flux is totally wrong! There seem to be no prozesses that make the neutrons loose energy and appear in a bin with less energy. That means, that there was only flux in the highest possible energy bin. What does this mean? How can I test and make sure that the program uses the hp-crosssections that I defined? I found the place in the code where the crosssection are that are used when there are no others defined. Unfortunately they are totally uncomrehensible. It seems to me that this part was direktly taken from the GHEISHA part of geant3 (which was not very well dokumentet in itself), leaving all description out: what is cnlwat,cnlwel,NCNLW,NELAB and all those cryptic numbers at the side?
Thanks a lot, Sylvia
