Detector outputs

Hi, my problem is due to the interpretation of the detector's output. Actually into the manual there is written that the detector's output shoul have 13 colums which the last (13') is the total number of scores. In my case the output shows just 12 colums. In my case I should plot "scores vs Etot/Ei"...

problem: Unable to initiate self-sustaining chain reaction

Hi, using the external source mode I get this error when I tried to lunch the program. Which could be the problem: Here below the code. surf earth inf surf hole cyl 0.000 0.000 5.0 cell 1 0 rock -earth hole cell 2 0 outside earth cell 3 0 fill 3 -hole mat rock 2.71 rgb 200 200 200 20000.06c -0.4 801...

Re: Paraffin as moderator

thank you very much, I will try to find those libreries otherwise I think I will use Graphite instead paraffin!

Thank you again!

Paraffin as moderator

Hi, I have a dubt, if I want to define paraffin as moderator What should I consider as moderator? Just Hydrogen or also Carbon? And so Will I do like here? %material paraffin, with density equal to 0.875 mat paraffin 0.875 moder MyThermLib 1001 1001.03c -0.15 6000.03c -0.85 therm MyThermLib lwj3.00t...

Re: Neutro log detector

Sorry for my delay in answering, yes I need to calculate the reaction all over the entire geometry (the goal is to see the amount of hydrogen into the rocks). So neutrons are emitted by AmBe (from the tool), they travel in the rock and then those which make elastic collisions with hydrogen return ba...

Neutro log detector

I would like to simulate a He3 detector, centered into a steel cylinder surrounded by a fluid. My energy section in between 0 and 4,5 MeV. Is this syntax correct? ene energy 3 500 1e-11 4.5e1 det 1 de energy du 0 dt -2 He3 where universe 0 is where there are the fluid, the steel cylinder, the source...

Re: Unable to sample initial fission source

Jaakko thank you, ok but what do you think obout the detector? Shoul I define a volume with inside He3 within the steel tool and than put that volume into the parameters of the detector or something else?

Re: Unable to sample initial fission source

Jaakko, thank you, yes is not a reactor is just a steel probe of 2 meters and 2 cm of diameter with a He3 chamber as detector in the top (40 cm from the top) and a neutron source in the bottom (40cm from the bottom) which is done with AmBe. The probe is inside a hole fill with a certain mud, the hol...

Neutron log simulation

Hi, my probelam is how to simulate a detector in my geometry. In real word the detector is inside a steel probe (a steel cylinder of 2 cm diameter and 2 m length), in the top part and is a cell of He3. So I approximate the entire geometry like here: %geometry of the rock surf earth inf %geometry of ...
