XFELX-Ray Free-Electron Laser
Possible Convenience Tools
• Possible areas where some “convenience” could be provided to ensure maximum efficiency during the 9mA run
• Directory of Property Names of Interest and their associated DAQ name (especially new properties)
• “Data of Interest” preprocessor• Thorough analysis of Dump temperatures to confirm
beam position• Convenient “Correlation Tool” which provides the most
useful correlations • “9mA Run Goal Monitor”

XFELX-Ray Free-Electron Laser
Directory of Property Names
• Goal• Table of property names of interest, description,
associated DAQ name• Preferably “query-able”
• Sources• List from Mariusz to John C (Aug 08)• Additions from Olaf• Numerous Matlab scripts • DAQ GUI Viewer, DDD screens • linac_main_run*_chan_dscr.xml
• <doocs>, <daqName>, <description>• Developers of new servers for August• Where else?

“Data-of-Interest” Pre-processor
• Planned 2 week run will generate a lot of data• How can we make accessing “data of interest” more
convenient?• For short periods of “data of interest” …
• Record time frame of interest • (e.g. 2009/09/11;15:15:00 – 2009/09/11;15:30:00)
• Record short description of event• Fetch data from DAQ and slow history for designated
“Channel Groups”• Store relevant data in a .mat file along with some
preprocessed results (plus a description)• Provide a report/list of stored events

9ma-Run Goal Monitor
• Primary Goals (from GDE AAP Review of April ‘09) • Demonstration of beam energy stability
• Over extended period• Characterization of energy stability limitations
• Operations close to gradient limits• Quantification of control overhead
• Minimum required klystron overhead for LLRF control• HOM absorber studies (cryo-load)
• Is there a semi-real-time monitor for beam energy stability?

Tools/Scripts for Operations
< slide from June 22; Controls/DAQ Topics >
• Script for on-the-fly analysis of cavity jitter
• Correlation Tool designed for most popular correlations
• Convert dump temperatures into beam position
• Script to analyze dump line BLM data
• Script to do cursory performance analysis of overnight run
• Hardware and software set-up for fast shutting down RF in case of BIS alarms
• Optimization of cavities filling procedure by phase modulation to reach possible high gradient
• Write Matlab script for quench and different kind of exception analyzes from DAQ data
