Description

BL 11-2 beamline description here: https://www-ssrl.slac.stanford.edu/mes/11-2/manual.php
https://www-ssrl.slac.stanford.edu/mes/Glitch_Curves/ , the instrument is the BL in the unfocussed and uncollimated mode
SSRL glitch database found here: https://www-ssrl.slac.stanford.edu/smbin/dataextractnew.pl
Documentation and results of the .instr here: https://gitlab.synchrotron-soleil.fr/grades/beamlines/-/tree/main/glitches
A jupyter notebook will soon be available regrouping everything.
You may scan like so for example:

Examples

(Test cases in bold)

• TestScan: mxrun SSRL_bl_11_2_white_src.instr -N31 Etohit=6900,7500 detuning_percentage=40 -n1e7 Detector: EnergyMonitor_first_I={31 values}
• Test: Etohit=6900 Detector: EnergyMonitor_first_I=3.74674e+09

Input parameters

Parameters in boldface are required; the others are optional.

Name	Unit	Description	Default
Etohit	eV.	Energy used to calculate the bragg angle the monochromator is put at. This is the energy we select.	6900
h	1	Miller indices.	2
k	1	Miller indices.	2
l	1	Miller indices.	0
fwhm	deg.	Full width half maximum of the second crystals's rocking curve.	0.1
detuning_percentage	%.	Percentage of the rocking curve fwhm to detune the second crystal by.	0
detuning_rockingcurve	deg.	Degrees to detune the second crystal by. Used to find the 2nd xtal's rocking curve. Leave at 0 otherwise.	0
