Experimental study of the main ring transition crossing

OSTI ID:6379092
A number of different experiments were proposed as part of the Fermilab III Instabilities Workshop in order to study the transition crossing in the Main Ring. Due to time limitations and operational restrictions only one of the experiments was actually performed. The results and analysis presented here are preliminary. We used an injection mismatch to deliberately blow up the longitudinal emittance in the MR 29 cycles, and measured the increase in bunch emittance and the particle loss through transition as functions of the initial bunch emittance. The experiment was repeated for different intensities (2, 4 booster turns) and for different rf voltages around transition. The purpose of the experiment was to distinguish the mechanism that is responsible for emittance growth and particle loss across transition. 4 refs., 7 figs.
