Abstract
Studies have been made of the transmission of positive ions through the gating grid of a time projection chamber operated synchronously at a high rate. With a duty cycle of 25% (22 μs periodic wave form) it has been demonstrated that less than one positive ion in 7 × 10−3 traverses the gating grid. This new gating technique can be used by a time projection chamber operating at the LEP e+e− collider.
