Hi Alex, Thank you very much for your suggestions. I have modified the code according to your recommendations. The previous error has now been resolved, but a new error has appeared. I am attaching txt format of the code and a screenshot of the fatal error for your reference. I am unsure...

Hi Alex, Thank you for your kind reply. I have taken the si sp data from ISO_8529_1(2001) Report. Here from the Source strength, i have taken the values as source probability. I didn't normalized the whole probability to one. I thought MCNP will do it itself. My MCNP Version is 5, I need to...

To calculate the angular momentum of the remaining rod, I think to substract the angular momentum of the dropped part from primary angular momentum. But I am confused about to calculate the angular momentum of the dropped part. How can I calculate that?

In figure AO = OB = 4m. C is the midpoint of AO. The rod rotates with a velocity of 5 rad/s about the axis PQ. What will be the rotational velocity of the remaining rod if AC part is suddenly dropped from the rod? Assume that the mass of this uniform rod is M.

I have corrected this fatal error, but still no photon is being recorded. i am attaching the input and output file.

Hi @Alex A and @PSRB191921. I am sorry, i uploaded the incomplete output file. In the mean time, i have changed the geometry. I have changed the par and tally too. But when the electron is emitted, it doesn't collide with the tungsten target. I am not sure why this is happening. Can you help me...

Here is my output.

I don't know where is the problem. My supervisor couldn't provide me the actual specification of my X-ray tube. I was asked to simulate the X-ray narrow spectrum beam. I run that code, but it produces nothing. Can anyone help me?

Can I input the X-Ray tube voltage in MCNP source specification?

Here, SP stands for source probability. But probability needs to be normalized. Here values in SP3, SP4 are larger than 1, It means that SP is not ordinary probability here. But what actually SP represent here?

What is meant by SP1,SI1 and SB here? I actually can't get the physical significance. And What is the physical significance of WGT here? Sorry for my this kind of questions. I am novice in MCNP.

Thank you so much!

What is meant by 2M and 20R here?
