Thank you. As my version is mcnp4c2, error occurred when I typed tmesh code. I think the code should be fine. I have to ask for more updated version. Which version should I use? mcnp6 or mcnpx?Thank you again.
I would like to calculate the dose rate like the above graph.
So, I have to define the every small cell inside the room?
Any other method to do this?
Thank you.
Thanks PSRB191921
I have tried nps 10000000
The results were ok.
Just one more question
How to perform mesh tally inside the room?
I wanted the dose rate result inside the room F6:P 1 could be visualized in MCNP VE. Thanks a lot!
I tried
wwp: p 4j 1
wwg 6 5
wwge:p .01 0.1 0.14
mesh GEOM=cyl...
Sorry for the late response.
I have updated the code, but still the F4 and F6 tally in cell 15 was zero.
The source came out from the X-ray tube could not reach the tally box and even the plastic phantom behind.
Is there anything wrong about the geometry? Thanks a lot!
Dear all,
I would like to simulate X-ray tube and check the dose rate in the room.
My problem is when I simulate 80kV electrons bombard to the tungsten target, there is just a few photons coming out from the tube window. And the dose rate at 1m from the tube is nearly zero which is impossible...
