Benchmarking the Use of BPM Quadrupole Moments to Measure Emittance
M. A. Balcewicz, C. Y. Tan
For the PIP-II program, transverse emittance in the Fermilab Booster must remain well controlled at higher bunch intensities. 4-plate beam position monitors (BPMs) have a small but…

Fermilab Booster Beam Emittances from Quadrupole Modes Measured by BPMs
C. Y. Tan, M. Balcewicz
The measurement of beam emittances by extracting the quadrupole mode signal from a 4 plate beam position monitor (BPM) was published at least 40 years ago. Unfortunately, in practi…
