Modulator systems for the ESS 2.5 MeV fast chopper

摘要

Modulator system requirements for the ESS 2.5 MeV slow wavechopper are considered to be challenging. A description is given ofcandidate modulation schemes, and modulator configurations, where thechopper E-field is generated by a gated high frequencysinusoidal/trapezoidal waveform or by a combination of fast transitionshort duration, and slow transition long duration, trapezoidal pulses
