yields

Yields vs. heep offsets 02/06/06

The yields were calculated for hydrogen and carbon production runs for the following cases:

dth_ss = 0.5
dp_ss = 0.5
dth_hs = 0.5
dp_hs = 0.5
dE = 0.5

The change in the yields is shown below.

diff(%) = 100*(normalized_yield_new - normalized_yield_old) /normalized_yield_old

Where normalized_yield_old is the normalized yield without any shifts.

The numbers below are for the missing mass cut mmx<1.020.

From these results, it can be seen that dE is the most important offset resulting in a 0.8% shift in the carbon yield, followed by dp_hs with resulted in a 0.6% shift in the carbon yield. The yield is least sensitive to dth_hs, which resulted in a 0.1% shift in the carbon yield.
