New Approaches in designing a Zeeman-Slower

We present two new approaches for the design of a Zeeman-Slower, which rely on optimal compliance with the adiabatic following condition and are applicable to a wide variety of systems. The first approach is an analytical one, based on the assumption that the noise in the system is position independent. When compared with the traditional approach, which requires constant deceleration, for a typical system, we show an improvement of $\sim$ 10% in the maximal capture velocity, allowing for a larger slower acceptance, or a reduction of $sim$ 25% in slower length, allowing for a simpler design and a better collimated beam. The second approach relies on an optimization of a system in which the magnetic field and the noise profile are well known. As an example, we use our 12-coil modular design and show an improvement of $sim$ 9% in maximal capture velocity or, alternatively, a reduction of $\sim$ 33% in slower length as compared with the traditional approach.
