Description
The longitudinal magnetic field profile of the Adiabatic Matching Device critically determines positron capture efficiency. While traditional designs prioritize the long adiabatic decay, this study investigates the often-overlooked non-adiabatic rise from the target exit field $B_0$, to the peak field $B_{\text{peak}}$. By systematically varying $B_0$, $B_{\text{peak}}$,, and the rise distance Z, we analyzed their impact on positron yield. Results demonstrate that the magnetic field gradient in this initial phase is pivotal. Specifically, optimizing the $B_0$/$B_{\text{peak}}$ ratio and minimizing the rise distance significantly enhances capture efficiency. These findings provide essential optimization strategies for high-performance positron sources.
