double GCOMInstChars::multi_scatter ( const double &  energy,
const double &  phigeo 
) const

Return multi-scatter correction.

Parameters
[in]energyInput photon energy (MeV).
[in]phigeoGeometrical scatter angle (deg).
Returns
Correction factor due to multi-scatter.

Returns the fraction of photons that have undergone a single scatter and which leave the D1 module unattenuated (no second interaction when traversing the remaining path inside the same module).

RES already calculates the fraction of photons which undergo a single scatter for VERTICALLY indicent photons, based on the Klein-Nishina cross-section and the composition of NE213A. Therefore the above mentioned transmission can be applied as a multiplicative correction per phigeo. However, in order to calculate that correction, an integral over the module must be performed, which properly takes into account the radiative transfer inside the module at all R and z. We again use the assumption of vertical photon incidence, which simplifies the calculation. The integral is done over the location of the first interaction.

Note that the transmission calculated is conservative : in reality it will be a bit higher because of a fraction of the photons which undergo a second scatter have a final scatter angle after escaping the module within the phigeo-range of the PSF. These events will, however, mainly be located at large phibar (large D1E deposit).

The code implementation is based on the COMPASS RESPSIT2 function MULTIS.F (release ?, 27-NOV-92).
