To　meet　linear　transformer　driver　requirements,　such　as　low　inductance　and　long　life,　a　planar　multi-gap　multi-channel　gas　switch　working　under　atmospheric　pressure　is　investigated　in　this　paper.　A　high　speed　ICCD　framing　camera　is　used　to　catch　the　images　of　discharge　channels.　Some　useful　images　are　obtained　by　the　camera　and　help　us　to　understand　the　developing　process　of　multiple　discharge　channels.　The　results　of　experiments　show　that　the　switch　can　be　triggered　reliably　and　the　framing　camera　images　provide　the　evidence　of　multiple　discharge　channels.　We　calculated　the　inductance　of　circuit　and　switch,　which　indicates　that　multiple　discharge　channels　are　beneficial　to　the　reduction　of　the　inductance.　The　relatively　uniform　erosion　spots　of　the　electrodes　imply　that　the　randomness　of　spatial　distribution　of　discharge　channels　helps　to　prolong　the　life　of　the　switch.　However,　the　different　breakdown　probability　of　each　discharge　channel　and　the　difference　among　discharge　channels　may　influence　the　life　of　switch.　Influence　of　working　coefficient　and　triggering　voltage　on　the　inductance　of　the　switch　and　the　number　of　discharge　channels　are　also　studied.　These　work　and　results　may　give　us　some　guidelines　to　design　and　apply　a　multi-gap　multi-channel　gas　switch　in　the　future.
