An effective, long-lasting, low-energy source of negatively charged ions was designed, constructed, and tested. The source uses electron dissociative attachment in electron-molecule collisions to form a set of anions inside a linear Paul trap. Iodine I2 molecules were used to obtain pure sets of I− anions. The system was tested, providing about 105 ions produced in less than a minute, which can be stored in the trap and used in further experiments.

Abstract
An effective, long-lasting, low-energy source of negatively charged ions was designed, constructed, and tested. The source uses electron dissociative attachment in electron-molecule collisions to form a set of anions inside a linear Paul trap. Iodine I2 molecules were used to obtain pure sets of I− anions. The system was tested, providing about 105 ions produced in less than a minute, which can be stored in the trap and used in further experiments.File in questo prodotto:
