“Fair-wind gas cell”—a new concept of a buffer gas cell design

A new concept of the buffer gas cell design is presented for the first time. For fast and efficient transport of stopped ions through the gas cell and afterwards to guide them out of the cell, the use of an intensive compulsory buffer gas flow through the cell combined with an RF-funnel structure is suggested. The operation of this type of gas cell that we call the fair-wind gas cell has been investigated by means of detailed computer simulations. Results of calculations for big size gas cell at 1 bar He buffer gas pressure are presented and discussed.
