Description

Generic TAS instrument for test of samples with dispersions. Modeled over the RITA-2 instrument at PSI (one analyzer only). The instrument is able to position in q-space at q=(h 0 0) and fixed Ei and Ef. This can be used to longitudinal constant-E scans or constant-q scans. In addition, transverse constant-E scans can be made by scanning the sample orientation A3.

Example: Test_Magnon_bcc_TAS.instr hw=0,1 -N21

Input parameters

Parameters in boldface are required; the others are optional.

Name	Unit	Description	Default
hw	meV	Neutron energy transfer	0.5
Ef	meV	Final neutron energy	5
A3offset			0
A3auto	0=manual; 1=auto	[1] Flag for selecting automatic setting of A3 to have q-vector along [h 0 0]	1
aa	passed on to the sample component	[Å] lattice parameter for cubic system	4.5
qh	1	Length of the q-vector in r.l.u., sets the value of scattering angle A4. If A3auto=1, then A3 is set to q=[qh 0 0]	1.1
highres	0=standard TAS / RITA2; 1=high resolution TAS	[1] Flag for setting unrealistic high resolution (used for fine testing)	0
sample_J	meV	Nearest Neighbor magnetic interaction in sample	0.2
TT	K	temperature	300
FerroMagnet	-	Flag: 1 if ferromagnet, 0 if AFM	0
Verbose	0=silent, 1=print	[1] Flag for printing of test statements from magnon component	0
