Detailed Description

Tool class to calculate the non-ionising radiation damage on the STS silicon.

Author

Volker Friese v.fri.nosp@m.ese@.nosp@m.gsi.d.nosp@m.e

6 December 2011

This class provides some functionality to calculate the effects of non-ionising irradiation on Silicon.

While the calculation of the NIEL factor is independent of the type of silicon used, those of leakage current and full depletion voltage depend on the specific silicon properties (effective doping concentration 9 x 10^11 cm^-3).

GetNiel() [1/2]

Double_t CbmStsRadTool::GetNiel	(	Int_t	type,
		Double_t	energy
	)

Get NIEL factor

Parameters

type	Particle Id (PDG code)
energy	Energy in GeV

Returns

NIEL factor

Calculates the NIEL factor for a given particle type and energy from interpolation of the values tabulated in http://sesam.desy.de/members/gunnar/Si-dfuncs.htm

Will return 0 for particle types other than proton, neutron, pion or electron, or if the energy is below the lowest tabulated value. Will return an asymptotic value if the energy is above the highest tabulated value.
