What is a unit of time listed in MCNP6 PTRAC output file?

AI Thread Summary
The unit of time in the MCNP6 PTRAC output file is the shake, which equals 10 nanoseconds. This unit is commonly used in nuclear physics due to its relevance in the timescales of nuclear events and chain reactions. The discussion highlights the difficulty in finding this information in the MCNP manual. The user initially speculated that the time might be in milliseconds or microseconds, but the shake is the correct unit. Understanding this unit is essential for accurately analyzing PTRAC output data.

Time unit in MCNP6 PTRAC
Hi everyone,

I've been trying to analyze PTRAC output file from MCNP6

here we can see the location , cell, particle, time, and so on...

My question is, I have trouble finding the unit of time listed in PTRAC, (ex, 0.30113E-02), which is hard to find in MCNP manual

My intuition is that the time unit is in milisecond, or microsecond

Does anyone know the answer of this simple question?

The natural unit of time in MCNP is the shake. 1 shake is 10ns. It's a convenient scale for nuclear events and it's the right order for one generation in a chain reaction so there is a lot of history attached to it. Could that be the right for the parameter you are looking at?
 

Thread 'Energy Spectrum Attenuation'

Hello, I'm currently trying to compare theoretical results with an MCNP simulation. I'm using two discrete sets of data, intensity (probability) and linear attenuation coefficient, both functions of energy, to produce an attenuated energy spectrum after x-rays have passed through a thin layer of lead. I've been running through the calculations and I'm getting a higher average attenuated energy (~74 keV) than initial average energy (~33 keV). My guess is I'm doing something wrong somewhere...
