  The fu­ture cir­cu­lar col­lider (FCC) re­quires a highly re­li­able in­jec­tion kicker sys­tem. Pre­sent day kicker sys­tems often rely on thyra­tron-based pulse gen­er­a­tors and a pulse form­ing net­work or line: the thyra­tron is sus­cep­ti­ble to self-trig­ger­ing. Hence, an al­ter­na­tive pulse gen­er­a­tor topol­ogy, based on fast semi­con­duc­tor switches, is con­sid­ered for the FCC. One pos­si­bil­ity is an in­duc­tive adder (IA). A pro­to­type IA has been de­signed and built: the main chal­lenges are the fast rise time, high out­put cur­rent, low sys­tem im­ped­ance and a 2.3 us pulse du­ra­tion com­bined with low droop. This paper pre­sents the re­sults of mea­sure­ments on the pro­to­type IA where the rated out­put cur­rent and out­put volt­age were achieved sep­a­rately. Sug­gested im­prove­ments to the IA hard­ware are iden­ti­fied and pro­pos­als are pre­sented that could help im­prove the kicker sys­tem per­for­mance.
