Ref: http://www.aesj.or.jp/publication/pnst002/data/866-871.pdfIn MCNP the term fission energy deposition is used as the neutron flux is not sampled in physical units of cm-2s-1 but in cm-2 per source neutron. Because of the missing time unit the term energy deposition is more correct. Nonetheless, we will often use the term power as it is normally used in nuclear reactor nomenclature.
F7 tally is a method used in science to measure the frequency of a specific event or outcome. It differs from power distribution, which is a statistical technique used to analyze the distribution of power in a system or group.
F7 tally can be used in various fields such as biology, psychology, and sociology to measure the frequency of behaviors, events, or outcomes. It is commonly used in experiments to collect quantitative data and analyze the results.
F7 tally involves counting the number of times a specific event occurs and recording it in a tally chart. For example, if you are recording the frequency of a certain behavior, you would mark a tally for each occurrence of that behavior. After a set period of time, the tallies are counted and converted into numerical data for analysis.
F7 tally allows for more precise and accurate data collection compared to other tallying methods. It also allows for easy comparison and analysis of data, making it a useful tool in scientific research.
One limitation of F7 tally is that it can only measure discrete events and may not be suitable for measuring continuous variables. It also requires manual counting and recording, which can be time-consuming and prone to human error. Additionally, F7 tally may not be appropriate for all types of research and may need to be supplemented with other methods for more comprehensive data collection.
