Integrated asymmetry calculation

[math] Asymm = \frac {\sum \left[\left(\frac{up(ii)}{Wup}-\frac{upbg(ii)}{Wupbg}\right) - \left(\frac{sd(ii)}{Wsd}-\frac{sdbg(ii)}{Wsdbg}\right)\right]} {\sum \left[\left(\frac{up(ii)}{Wup}-\frac{upbg(ii)}{Wupbg}\right) + \left(\frac{sd(ii)}{Wsd}-\frac{sdbg(ii)}{Wsdbg}\right)\right]} [/math]

where

up(ii)   - D2O, detector Up,   Wup - weighted coefficient for up(ii)
upbg(ii) - H2O, detector Up, Wup - weighted coefficient for upbg(ii)
sd(ii) - D2O, detector Side, Wup - weighted coefficient for sd(ii)
sdbg(ii) - N2O, detector Side, Wup - weighted coefficient for sdbg(ii)

For detector A summation is over [1000:1600] bin numbers
For detector C summation is over [900:1600] bin numbers

Cases was analysed

Det A:

D2O Up,   files# [40,56,102,108,134,205,210,230];
H2O Up, files# [44];
D2O Side, files# [48,74,78,82,86,90,94,146,180,190,225,235];
H2O Side, files# [52];

Det C:

D2O Up,   files# [49,75,79,83,87,91,95,147,181,191,226,236];
H2O Up, files# [53];
D2O Side, files# [41,57,103,107,135,206,211,231];
H2O Side, files# [45];

The results are (File:Asymm table.pdf):

  • Table 1: Det A, weighted with NaI detector
  • Table 2: Det C, weighted with NaI detector
  • Table 3: Det A, weighted with Ref detector
  • Table 4: Det C, weighted with Ref detector


Change the X-axis to nanosecond or neutron energy (TF)
Only one "s" in Asymmetry
