Greenberg J, Krohn O, Bossert J, Shyur Y, Macaluso D, Fitch N, et al.
Rev Sci Instrum . 2021 Oct; 92(10):103202. PMID: 34717395
Producing high densities of molecules is a fundamental challenge for low-temperature, ion-molecule reaction studies. Traveling-wave Stark decelerators promise to deliver high density beams of cold, polar molecules but require non-trivial...
