What?
- Java library
- Extract MQT powerconverter values for a certain time
- Used for the best knowledge model
- MAD-X format -> Timber format -> NXCals variable

How? (I)
- acc-co repo:
https://gitlab.cern.ch/acc-co/lhc/lhc-k_extractor
- Simple interface:
// Call the extractor and save the result to the file specified earlier KExtractor kextractor = new KExtractor(KExtractor.createContext()); kextractor.getKValuesForBeam(beam, timestamp, filepath);

Current Problems
- Slow. Between 1 and 8 minutes for one beam (16 vars)
∘ Querying one variable at a time, can and will be improved
