Description

Source-like component that reads neutron state parameters from a binary mcpl-file.

MCPL is short for Monte Carlo Particle List, and is a new format for sharing events
between e.g. MCNP(X), Geant4 and McStas.

When used with MPI, the --ncount given on the commandline is overwritten by
#MPI nodes x #events in the file.

Input parameters

Parameters in boldface are required; the others are optional.

Name	Unit	Description	Default
filename	str	Name of neutron mcpl file to read.	0
polarisationuse		If !=0 read polarisation vectors from file.	1
verbose		Print debugging information for first 10 particles read.	1
Emin	meV	Lower energy bound. Particles found in the MCPL-file below the limit are skipped.	0
Emax	meV	Upper energy bound. Particles found in the MCPL-file above the limit are skipped.	FLT_MAX
repeat_count	1	Repeat contents of the MCPL file this number of times. NB: When running MPI, repeating is implicit and is taken into account by integer division. Should be combined sith the _smear options!	1
E_smear	1	When repeating events, make a Gaussian MC choice within E_smear*E around particle energy E	0
pos_smear	m	When repeating events, make a flat MC choice of position within pos_smear around particle starting position	0
dir_smear	deg	When repeating events, make a Gaussian MC choice of direction within dir_smear around particle direction	0
preload		Load particles during INITIALIZE. On GPU preload is forced.	0

AT (	,	,		) RELATIVE		Generate
ROTATED (	,	,		) RELATIVE
