Abstract
An ion processing unit (10) comprising a series of M perforated electrode sheets (12), driving electronics (14,16) and a central processing unit (18), allow formation, shaping and translation of multiple effective potential wells (42). Ions, trapped within a given effective potential well (42), can be isolated, transferred, cooled or heated, separated, and combined. Measurement of induced image currents allows measurement and typing of ion species by their respective mass-to-charge ratios. The combination of many electrode sheets (12), each having N multiple perforations (22), creates any number of parallel ion processing channels (26). The ion processing unit (10) provides an N by M massively parallel ion processing system, furnishing means for processing large numbers of ions in parallel in the same manner, but with different ion processes deployed at different sections of each ion processing channel (26). In addition, the space-filling parallel structure of the present invention provides an efficient means for storage of large numbers of ions, including charged antimatter.
