UTU SEP Products: Proton fluence

Plot data will appear here. Use the inputs on the right!

SEP fluence probability calculator

Given a specified mission length and proton energy channel, this tool generates a fluence-probability graph (and table).
Data can be created as either cumulative or worst-case.

Model to use:
Mission length [a]:
Energy channel:
Cumulative / Worst case:

SEP fluence energy spectrum calculator

Given a specified mission length and confidence level, this tool generates a graph (and table) listing the fluence energy spectrum that will not be exceeded.
Data can be created for either differential or integral fluence.

Model to use:
Mission length [a]:
Confidence level:
Differential / Integral:
