This SNAPIN section reads the power and energy of each beam source and time-averages them over the interval You can also model a different beam mix from the one in the actual shot, e.g., you can specify tritium rather than deuterium beams.
\* Options are: 1) 1A [ 96.11 +/- 1.5%, 2.36 +/- 1.5%] T 2 -1.74 V(keV) P(MW) On a# Rtan 2) 1B [ 99.66 +/- 1.9%, 2.52 +/- 1.8%] T 2 -2.00 3) 1C [ 97.75 +/- 1.5%, 2.53 +/- 1.5%] T 2 -2.23 4) 2A [ 97.73 +/- 1.6%, 2.52 +/- 1.6%] T 2 -1.74 5) 2B [ 96.16 +/- 1.6%, 2.35 +/- 1.6%] T 2 -1.99 6) 2C [ 91.78 +/- 1.7%, 2.02 +/- 1.7%] T 2 -2.23 7) 4A [ 0.00 +/- 0.0%, 0.00 +/- 0.0%] F 2 2.29 8) 4B [ 90.05 +/- 1.5%, 1.94 +/- 1.5%] T 2 2.05 9) 4C [ 91.76 +/- 1.4%, 2.09 +/- 1.4%] T 2 1.80 10) 5A [ 93.94 +/- 1.7%, 2.23 +/- 1.7%] T 2 2.23 11) 5B [ 88.20 +/- 1.5%, 2.08 +/- 1.5%] T 2 1.99 12) 5C [ 96.35 +/- 1.4%, 2.34 +/- 1.4%] T 2 1.73 13) No No beams 14) Hy Hydrogen beams 15) De Deuterium beams 16) Tr Tritium beams 17) Mixed Species 18) READ beam data, source is WAVEFORMS 19) Shape and fractions 20) Thermal T conc = Beam conc <F>You can also specify the beam shape and energy fractions--setting these numbers will change these values for all the beams.

A large collection of SNAP analysis used values for the beam footprint that are now considered to be too narrow; SNAPIN will warn you if you are not using the new standard values.
