Effusive Atomic Oven Nozzle Design Using an Aligned Microcapillary Array
arXiv:1407.6391 · doi:10.1063/1.4907401
Abstract
We present a simple and inexpensive design for a multichannel effusive oven nozzle which provides improved atomic beam collimation and thus extended oven lifetimes. Using this design we demonstrate an atomic lithium source suitable for trapped-atom experiments. At a nozzle temperature of 525C the collimated atomic beam flux directly after the nozzle is atoms per second with a peak beam intensity greater than atoms per second per steradian. This suggests an oven lifetime of several decades of continuous operation.
