Cross-sectional view of SIMION ion trajectory simulations for a TW-SLIM elevator module operating when the elevator is (a) disabled and (b) enabled by applying a bias voltage to the two TW electrodes across from the orifice. Arrows indicate the direction of ion motion. Simulations were performed with 100 particles using rf parameters of 150 Vp-p at 1 MHz and TW parameters of 30 V amplitude at speed of 200 m/s and a sequence of 11110000.
