2nd example
This is a measuring on a HZG 4 from the firm Seifert-FPM. Polymers commonly
show reflections at very low angles. Therefore, primary and secondary soller
slits are both in use. Please, remark the 1.6mm thick sample with
a mu=3.3/cm! The detector is a semiconductor one for Kbeta separation.
It's window (size of 8mm) was chosen instead of the monochromator crystal's
hight and position. The command file is as follows:
VERZERR=vjeh03 R=250 FocusH=10 FocusW=0.1 HSlitR=85 HSlitW=0.44 VSlitR=75 VSlitH=4 PColl=0.5/25 SamplD=12 DetW=0.22 DetH=8 MonR=R+8 zweiTheta[1]=3 zweiTheta[2]=4 zweiTheta[3]=5 zweiTheta[4]=6.5 zweiTheta[5]=8 zweiTheta[6]=10 zweiTheta[7]=14 zweiTheta[8]=20 zweiTheta[9]=28 zweiTheta[10]=40 zweiTheta[11]=60 zweiTheta[12]=80 T=1.6 D=T/0.53012 WMIN=3 WMAX=80 pi=2*acos(0) WSTEP=2*sin(zweiTheta*pi/180) GSUM=Y
3th example
This was a measuring at an 3000TT diffractometer in transmission. The
thickness of the specimen was estimated to 0.2mm. Because of the high
linear attenuation coefficient of 250/cm the intensity is lowered for more
than a magnitude. And there is a strong lowering of intensity for larger
2 theta angles. For compensation, this measuring was done without secondary
soller slits. The command file is as follows:
VERZERR=tran0205.ger GEOMETRY=TRANSMISSION R=250 D=0.08 T=0.2 HSlitR=R-150 HSlitW=0.2 VSlitR=R-80 VSlitH=17 FocusH=12 FocusW=0.04 DetH=14 MonR=R+50 DetW=0.5 SamplD=20 PColl=0.54/25 zweiTheta[1]=6 zweiTheta[2]=10 zweiTheta[3]=16 zweiTheta[4]=24 zweiTheta[5]=34 zweiTheta[6]=48 zweiTheta[7]=60 zweiTheta[8]=90 zweiTheta[9]=120 WMIN=6 WMAX=120 pi=2*acos(0) WSTEP=3*sin(pi*zweiTheta/180)
4th example
This example shows the possibility of computation of capillary (or wire)
geometry. The parameters capillary diameter and linear attenuation
coefficient represent a realistic case for mineralic samples. Until now,
we have not really used this capillary geometry. Please remark the double-peak
at low angles, well known in Debye-Scherrer-films from high absorbing
specimens. You also can see the common fact of increasing intensity with
2 theta angle. The command file is as follows:
VERZERR=capillar GEQ=capillar GEOMETRY=CAPILLARY R=250 FocusH=10 FocusW=0.1 HSlitR=85 HSlitW=0.44 VSlitR=75 VSlitH=4 PColl=0.5/25 SColl=0.5/25 DetW=0.22 DetH=8 MonR=R+8 zweiTheta[1]=3 zweiTheta[2]=4 zweiTheta[3]=5 zweiTheta[4]=6.5 zweiTheta[5]=8 zweiTheta[6]=10 zweiTheta[7]=14 zweiTheta[8]=20 zweiTheta[9]=28 zweiTheta[10]=40 zweiTheta[11]=60 zweiTheta[12]=80 WMIN=3 WMAX=80 pi=2*acos(0) WSTEP=5*sin(zweiTheta*pi/180) D=0.08 T=0.5
