measured beam lifetime after the second deceleration using parallel plate Schottky detector and the RSA5103 spectrum analyser. Analysis code can be found here: https://github.com/xaratustrah/e127_scripts/ The plots here were produced using the script: https://nbviewer.ipython.org/github/xaratustrah/e127_scripts/blob/main/lifetime_calculator.ipynb UPDATE 2022-06-30: Life times have been slightly corrected.
