Hello, my name is Jaromir Ludwin. You might find me occupied with:

• Electrical Quality Assurance of the LHC superconducting circuits and other tasks generally related to electrical integrity testing and electrical failure diagnostics. If you are interested in the subject, here is my one-hour long lecture on electrical integrity: https://videos.cern.ch/record/2301707
• A measurement automation using NI LabVIEW and Python, databases, and web application developlent. Very useful for automation of the electrical integrity testing.
• Photography (when I'm not at work).

Most of the time, I am at the Institute of Nuclear Physics of the Polish Academy of Sciences in Krakow, where I work in the Division of Scientific Equipment and Infrastructure Construction. I have been coming to CERN from time to time since 2006, taking part in the assembly of the LHC, recovery after 2008 incident, all long shutdowns and most of the year end technical stops. I also did a tiny bit of work related to the super conducting RF cavity testing during the construction of European X-FEL back in 2009-2011.

I was a co-author of the following publications:

• J. Ludwin et al. - Upgrade of the automatic DC high voltage multichannel insulation tester for superconducting circuits of the LHC
• M.B.B. Christensen et al. - Impedance Characterization of a HL-LHC Nb₃Sn MQXFS Model Magnet During Powered Operation at Nominal Current
• A. Abdul Halim et al. - The scintillator surface detector of the Pierre Auger observatory
• T. Podzorny et al. - Continuous Diagnostics for Powered Superconducting Circuits
• M. Janitschke et al. - Analyzing the Complex Impedances of All LHC Main Dipole Magnets,
• M. B. B. Christensen et al. - Enabling Real-Time Impedance Measurements of Operational Superconducting Circuits of Accelerator Magnets,
• J. Ludwin et al. - New Measurement Techniques Used for the Electrical Quality Assurance of HL-LHC Superconducting Magnets,
• J. Ludwin et al. - Preparation and execution of the electrical quality assurance program on the LHC superconducting circuits during the second Long Shutdown
• M. Bednarski et al. - Upgrade of the Arc Interconnection Verification System for the Large Hadron Collider
• J. Ludwin, P. Jurkiewicz - Upgrade of the automatic measurement system for the electrical verification of the LHC superconducting circuits
• M. Bednarek, J. Ludwin - Software Tools for Electrical Quality Assurance in the LHC
• J. Niemiec et al. - Single-Mirror Small-Size Telescope structure for the Cherenkov Telescope Array
• SuperB Collaboration - SuperB Technical Design Report
• A. Kotarba et al. - Automatic Measurement System for Electrical Verification of the LHC Superconducting Circuits
• D. Bozzini et al. - Automatic System for the D.C. High Voltage Qualification of the Superconducting Electrical Circuits of the LHC Machine
• D. Bozzini et al. - Electrical Quality Assurance of the Superconducting Circuits during LHC Machine Assembly

I've had the opportunity to discuss my work in the media a few times:

• (PL) RMF24, Interview during visit of Polish journalists at CERN, 2019. By the way I said that CERN uses the same amount of electricity as canton of Geneva. I was wrong. It only uses 1/3rd of that.
• (PL) RTvG, My interview in the local TV station from my home town, 2014
• (PL) TVP, Popular science show in Polish national TV, where I appear for a few seconds, 2013
• (EN/FR) CERN Bulletin, Increasing the potential, 2013

There's also the Robot Zenek video... for those who like robots.
