package FluxSvc

Authors:

Toby Burnett, Sean Robinson, Theodore Hierath, and others.

Introduction

This package implements a Gaudi service, encapsulating the flux package. Its only function is to return an IFlux object, whose methods are implemented by the flux package.

The FluxSvc package is designed to hold information on : the orbital characteristics of GLAST, the Emissive characteristics of various sources, and the 'Current' time and a model for particle emission from desired sources.

Through implementing a Gaudi Service (FluxSvc.h), it: Takes user specifications on desired source/sources, Provides a user interface to produce additional incoming particles, and Provides the current time, particle energy, direction, and type of particle.

the file /src/test/jobOptions.txt holds information used for the implementation of FluxSvc. it also holds the standard set of strings representing xml filenames, thus allowing multiple xml files to be used. See here for an explanation of how Gaudi was introduced to flux to make FluxSvc, and further documentation:

Defining an external source

See the interface definition IRegisterSource.

jobOptions

Parameters:

FluxAlg.source_name	This is the source name (defined in the XML) that is to be used as a source in the simulation.
FluxSvc.source_lib	this is a list of the XML files that will make their declared sources available to the simulation. Basic_XML_Sources
default	0.1 GeV gamma-rays coming from the vertical local direction. Used for default tests.
albedo_gamma	Source that represents the Earth horizon albedo with Glast zenith pointing
chime	The CHIME spectrum. angular dependence and rate are from the CHIME spectrum object
He	The Helium spectrum. angular dependence and rate come from the HeSpectrum object.
albedo_electronpositron	Source that represents the spalsh and re-entrant albedo electrons and positrons
diffuse	diffuse extraglactic from 10 MeV: from APJ 494:523
diffuse-100mev	Diffuse extraglactic from 100 MeV
crab-galactic	the Crab, pulsed portion, with pointed observation, for photons above 100 MeV, based on Nolan APJ 409:697
electron	galactic electron spectrum
normal_gamma	E^-1 spectrum from 18 MeV to 18 GeV and normal incidence
muons	special source that mimics non-interacting cosmics
