Approach for an all solid state Klystron Modulator Project Hivomops: HiVoMoPS Technology Approach for an all solid state Klystron Modulator Specification: Up to 150kV Pulse Voltage Up to 150A Pulse Current Up to 5ms Pulse Width Up to 20Hz Repetition rate Up to 350kW Output Power The Idea: Make it simple Make it fit for mass production Make it fit for future developments in µC / FPGA technologies Scheme of the Hivo Stack

Project Hivomops: HiVoMoPS Technology Approach for an all solid state Klystron Modulator Simulation: 100kV Puls @ 200µs @60A Accuracy < 0.5% Ripple < 0.8% (will be reduced)

Project Hivomops: HiVoMoPS Technology Approach for an all solid state Klystron Modulator Excel sheet: Easy configuration Easy calculation

Project Hivomops: Blockdiagram

Project Hivomops: CAD General View Key features: Strong Modular Free programable All modular and fully Redundancy Cost-effective due to mass production No Oil; No Epoxy Isolation Easy implemented arcing protection easiest maintenance No Crowbar in fact in case of arcing, the whole stack works as a crowbar. Easy Integration Refurbishment solutions economically possible

Project Hivomops: CAD Design Fast AC Switch Pulse Module High Voltage Divider Diode Stack

Project Hivomops: Simulation and Reality The static field intensities in the high-voltage areas could be simulated in advance.

Project Hivomops: Partnership Special thank‘s to Prof. Dr.-Ing. Wolfgang Rehm Studiendekan HOCHSCHULE MÜNCHEN Fakultät für Elektrotechnik und Informationstechnik Labor für Hochspannungstechnik Lothstraße 64 80335 München

Project Hivomops: High Voltage Measurements Simulated HV Pulses increased until arcing events Pulse Measurement and accuracy tested

Project Hivomops: Status Hardware Both racks are ready mountet

Project Hivomops: Status Hardware Pulse Modules are in prototyping status Ready mounted Pulse Module, housing opened Secure HV Workbench with Pulse Module

Status Projekt Hivomops WebDiag Web based Diagnostic interface Proved and already working in the ISIS project Planned manual interface for Puls design

Production Proved and already working in the UNIBW as a three Phase AC Source and traction converter developed together with siemens. Everywhere easy to produce Rack simply mechanical Housing cost effective vacuum shaped plastic PCB producable and testable by every skilled PCB manufacturer Licensing to the customer for large amount of systems Therefore access to the technologie and spares

Thank you for your attention
