FEE spectrometer
FEE Spectrometer = XRT Spectrometer = XRT HXSSS
How to insert XPP monochromator:
$ ssh -X username@psdev
$ ssh -X xpp-monitor
$ cd ~xppopr
$ source .bashrc
$ xpppython
$ lom.h1n.mv(0) (this is the “in” position. Watch the mono going in on XCS YAG1)
$ lom.EC(desired keV)
When you are done:
$ lom..h1n.mv(-10) (this is the out position)
For a past example: Using XPP mono to calibrate XRT spectrometer

Prefocusing and Transfocator
This was the setting at 9.5 keV for LY00
Event Sequencer
Switching between 120 Hz ePix and 10/20/30 Hz Rayonix:
In the DAQ window, click Edit, then EVR0
For 120Hz:
Set event code 198 to Command and enable global event code 40
For 10/20/30 Hz:
Uncheck global event code 40 and set event code 198 to Readout (make sure Event Sequencer is set up correctly and running).
To change the binning, change the number of delta beams for event code 213 in the Event Sequencer to match the desired frequency. Then, in the DAQ window, click Edit, then Rayonix Config.
OR you can use:
$ mfx3
$ rayonix.configure_sequencer(the desired frequency in Hz)
Event sequence used for LX55 (10Hz laser and 30Hz Rayonix):
Code snippet to sort out "laser on" from other events: https://github.com/apeck12/sfx_utils/blob/TTscripts/sfx_utils/laser_state.py
For more details, see: Sequencer and LCLS timing and DAQ Event Code Configuration (EVR)
Autorun
How to run autorun script:
$ /cds/home/f/fmos/scripts/
autorun_v1.py does not open or close the pulsepicker.
autorun_v2.py switches the pulsepicker to either open or flipflop and closes the pulsepicker when the script is stopped.
$ mfx3
$ cd /cds/home/f/fmos/scripts/
$ from autorun_v2 import main as autorun
$ autorun(duration=300, mode=’flipflop’)
Duration is the time of each run in seconds and mode can be either ‘flipflop’ or ‘open’.
