Mechanical time-of-flight filter based on slotted disks and helical rotor for measurement of velocities of nanoparticles

Abstract A mechanical time-of-flight filter intended for measurement of velocities of nanoparticles exiting a gas aggregation source has been developed. Several configurations maximizing simplicity, throughput or resolution are suggested and investigated both theoretically and experimentally. It is...
