  Am­pe­gon in col­lab­o­ra­tion with the Lab­o­ra­tory for High Power Elec­tronic Sys­tems HPE/ETH Zurich, has de­vel­oped a novel short pulse mod­u­la­tor based on a ma­trix trans­former for high power mi­crowave kly­strons. The new mod­u­la­tor sys­tem com­plies with the fu­ture needs in the field of ac­cel­er­a­tors like FELs for re­search fa­cil­i­ties, but also for med­ical and in­dus­trial ap­pli­ca­tions in a most re­li­able, ef­fi­cient and pre­cise way. Spe­cial em­pha­sis has been given to a mod­u­lar and scal­able de­sign, a high level of re­dun­dancy and main­tain­abil­ity. This is achieved with a clear and ex­tend­able sys­tem lay­out, which al­lows easy ac­cess to all com­po­nents, and the use of stan­dard­ized com­po­nents. The pulse to pulse sta­bil­ity and high sys­tems ef­fi­ciency in com­bi­na­tion with a fast volt­age rise time com­plies with the re­quire­ments of fu­ture ef­fi­cient ac­cel­er­a­tor de­signs. After a suc­cess­ful test of a demon­stra­tor mod­u­la­tor, the in­dus­tri­al­ized full scale mod­u­la­tor based on the C-band RF sta­tion spec­i­fi­ca­tion of the Swiss­FEL pro­ject (PSI Paul Scher­rer In­sti­tute, CH) has been built and is cur­rently under test in the Am­pe­gon fac­tory. The poster will give an overview of the sys­tem con­cept and Shows first test re­sults.
