Detailed Description

Interface to BBNBI5.

BBNBI5 models neutral beam injectors and is used to evaluate shine-through and beam birth-profile. Neutral markers are generated from injector geometry and traced until they ionize or hit the wall. Several injectors can be modelled simultaneously keeping in mind that in this case the output the injector from which a particle originated is lost.

Function Documentation

bbnbi_trace_markers()

void bbnbi_trace_markers	(	particle_queue *	pq,
		sim_data *	sim )

Trace a neutral marker until it has ionized or hit wall.

This function is for the most part identical to simulate_fo with few exceptions relevant for BBNBI.

Parameters

pq	pointer to the marker queue containing the initial neutrals
sim	pointer to the simu struct with initialized data

Definition at line 227 of file bbnbi5.c.

bbnbi_inject_markers()

void bbnbi_inject_markers	(	particle_state *	p,
		int	nprt,
		int	ngenerated,
		real	t0,
		real	t1,
		nbi_injector *	inj,
		sim_data *	sim )

Inject neutrals from an injector.

This function initializes neutral markers at the beamlet positions and launches them in a (random) direction based on the injector specs. The marker is traced until it enters the magnetic field, at which point the particle struct is filled with only the particle data, and the struct is returned.

Parameters

p	pointer where generated markers are stored
nprt	number of markers to be injected or generated
ngenerated	number of markers that have already been generated
t0	time when the injector is turned on
t1	time when the injector is turned off
inj	pointer to injector data
sim	pointer to the sim struct with initialized data

bbnbi_simulate()

void bbnbi_simulate	(	sim_offload_data *	sim,
		int	nprt,
		real	t1,
		real	t2,
		real *	B_offload_array,
		real *	plasma_offload_array,
		real *	neutral_offload_array,
		real *	wall_offload_array,
		int *	wall_int_offload_array,
		real *	asigma_offload_array,
		real *	nbi_offload_array,
		particle_state **	p,
		real *	diag_offload_array )

Simulate NBI injection.

This function initializes neutrals and traces them until they have ionized or hit the wall.

Parameters

sim	pointer to the simulation offload data structure
nprt	number of markers to be injected
t1	time instant when the injector is turned on
t2	time instant when the injector is turned off
B_offload_array	pointer to the magnetic field data
plasma_offload_array	pointer to the plasma data
neutral_offload_array	pointer to the neutral data
wall_offload_array	pointer to the wall data
wall_int_offload_array	pointer to the wall int data
asigma_offload_array	pointer to the atomic sigma data
nbi_offload_array	pointer to the nbi data
p	pointer to the marker array which is allocated here
diag_offload_array	pointer to the diagnostics data
