Beam-Based Determination of the Offset of Booster gamma-T Quads
Xi Yang, Charles M. Ankenbrandt, James MacLachlan
Twelve pulsed gamma-T quads have been installed in the Booster to provide fast transition crossing. The less time the beam stays in the non-adiabatic period near transition, the le…
Applying Synchrotron Phase Measurement to the Estimation of Maximum Beam Intensity in the Fermilab Booster
Xi Yang, James MacLachlan
It is important to have experimental methods to estimate the maximum beam intensity for the Fermilab Booster as objective input into long term program commitments. An important exi…
Implications of beam phase and RFSUM measured near transition
Xi Yang, James MacLachlan
Understanding the transition-crossing process is crucial for improving Booster performance at high intensity. The synchronous phase appears to drop toward 90 degrees right after tr…
Booster Synchrotron Frequency Below Transition
Xi Yang, James MacLachlan, Rene Padilla +1
The dipole mode synchrotron frequency is a basic beam parameter; it and a few similarly basic quantities measured at small time intervals serve to characterize the longitudinal bea…
Indicators of the Energy Error in the Linac to Booster Transfer
Xi Yang, James MacLachlan
The match between the Linac beam energy and the energy determined by the bending field of the Booster magnets is crucial for rf capture, beam quality, and the transmission efficien…
Measurement of gamma-T with the gamma-T Quads On and Off
Xi Yang, James MacLachlan, Charles M. Ankenbrandt
An experimental procedure for measuring gamma-T has been developed and tested in two different measurements, with the gamma-T quads on and off. The results were compared to MAD cal…
