(DTI) has designed and built an advanced, high-voltage solid-state modulator for long pulse klystrons for ESS. In 2014, DTI, in partnership with SigmaPhi Electronics, received two contracts for production and installation of this design for ESS-class modulators, which will be used for the testing and conditioning of ESS klystron tubes and testing of RF components. This modulator design uses a hybrid configuration (solid state switch and pulse transformer) with an advanced switching regulator to maintain a very flat voltage into the klystron over multi-millisecond pulses. This paper will describe the design and testing of these modulators, and the status of their installation. The major development introduced in this design is that the millisecond-long pulses produce a droop voltage of about 10% with a reasonably-sized capacitor bank–much larger than the 1% droop required. To eliminate the droop without a large and expensive capacitor bank, the modulator uses a non-dissipative regulator.
