LoadIsawDetCal v1¶
Summary¶
Since ISAW already has the capability to calibrate the instrument using single crystal peaks, this algorithm leverages this in mantid. It loads in a detcal file from ISAW and moves all of the detector panels accordingly. The target instruments for this feature are SNAP and TOPAZ.

Description¶
Moves the detectors in an instrument using the origin and 2 vectors of the rotated plane from an ISAW DetCal file.
Usage¶
#Write a ISAW DetCal file
import mantid
filename=mantid.config.getString("defaultsave.directory")+"loadIsawDetCalTest.DetCal"
f=open(filename,'w')
f.write("5 1 256 256 50.1000 49.9000 0.2000 55.33 50.0000 16.7548 -16.7548 0.00011 -0.00002 1.00000 0.00000 1.00000 0.00000\n")
f.close()
iw = LoadEmptyInstrument(Filename="unit_testing/MINITOPAZ_Definition.xml",)
LoadIsawDetCal(InputWorkspace=iw,FileName=filename)
bank = iw.getInstrument().getComponentByName("bank1")
print("Position after LoadDetCal : {}".format(bank.getPos()))
Output:
Position after LoadDetCal : [0.5,0.167548,-0.167548]
