/**
|
|
* @brief Accumulable of RBE-related data (that must be thread-local).
|
|
*
|
|
* It keeps the sum of alpha and beta numerators/denominator, as well as energy deposits.
|
|
* The class is closely tied with the singleton HadrontherapyRBE that is used both
|
|
* to calculate alphas and betas, and also to store results.
|
|
*
|
|
* This is implemented as a customized G4VAccumulable with non-scalar data.
|
|
*
|
|
* @note There are two levels of merging (accumulation):
|
|
* 1) From more threads in one run (G4VAccumulable merging is applied)
|
|
* 2) (Optional) inter-run merging of data (implemented in HadrontherapyRBE).
|
|
*
|
|
* @note std::valarray is used (instead of C arrays or std::vectors)
|
|
* to accumulate data for its logical simplicity.
