LoadIsawDetCal v1

Enable screenshots using DOCS_SCREENSHOTS in CMake

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.

Properties

Name	Direction	Type	Default	Description
InputWorkspace	InOut	Workspace	Mandatory	The workspace containing the geometry to be calibrated.
Filename	Input	list of str lists	Mandatory	The input filename of the ISAW DetCal file (Two files allowed for SNAP) . Allowed extensions: [‘.detcal’, ‘.peaks’, ‘.integrate’]
Filename2	Input	string		The input filename of the second ISAW DetCal file (West banks for SNAP) . Allowed extensions: [‘.detcal’, ‘.peaks’, ‘.integrate’]
TimeOffset	Output	number		Time Offset

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]
