Appendix A Using the Monochromator Control Software 41
A.4.2 Grating Control Commands
GRATING Places specified grating in position to the wavelength of the wavelength
on the present grating. Up to nine (9) gratings are allowed on three (3)
turrets. This command takes a grating number from 1 - 9.
IMPORTANT NOTE: This command assumes that the correct turret is specified
by the TURRET command. For example, using grating numbers 1, 4 and 7 will
place the first grating on the installed turret into that position and call up the
parameters for the grating number specified.
?GRATING Returns the number of gratings presently being used numbered 1 - 9.
?GRATINGS Returns the list of installed gratings with position groove density and
blaze. The present grating is specified with an arrow.
TURRET Specifies the presently installed turret or the turret to be installed.
e.g., if installing the second turret, issue the command 2 TURRET to
insure using the correct parameters.
?TURRET Returns the correctly installed turret numbered 1 - 3.
The following command is used for grating installation by Acton part number:
INSTALL Installs new grating parameters into the non-volatile memory of the
IsoPlane monochromator. Uses the part number of the grating to specify
the parameters.
e.g., 1-120-500 5 INSTALL places a 1200 g/mm grating blazed at 500 nm
into the second grating position on turret number 2.
The following commands are used for grating installation by grating parameters:
SELECT-GRATING Specifies the grating number to be installed 1 - 9.
G/MM Specifies groove density of grating to be installed in g/mm.
e.g., 1200 G/MM
BLAZE Specifies the blaze wavelength and units of the grating to be installed with
7 characters of the user’s choice. Unlike other commands, this command
is issued before the parameters. After the command is issued, the IsoPlane
responds with ““ . Seven characters are then entered (these may be
numbers, letters, spaces or special characters).
UNINSTALL Used to remove a grating and its parameters from the IsoPlane
non-volatile memory.
