Design for a FET based 1 MHz, 10 kV pulse generator

A pulse generator consisting of a coaxial cable and a high voltage modulator, incorporating two stacks of Field-Effect Transistor (FET) switches operating in ``push-pull`` mode, has been designed and built. The modulator generates a continuous, unipolar, pulse train at a fundamental frequency of 1 MHz and a magnitude of 10 kV. The rise and fall times of the pulses are less than 39 ns. The two stacks each utilize 14 FETS, which are individually rated at 1 kV. The design incorporates a low-loss coaxial cable on which pulses are stored. Extensive PSpice simulations have been carried out to evaluate various design options. Subsequent measurements on the prototype pulse generator confirm the PSpice predictions. This system is applicable for the kicker system at TRIUMF

ANALYZING POWER MEASUREMENTS IN πd ELASTIC SCATTERING AT 50 MeV

Nos mesures du pouvoir d'analyse vectoriel dans la diffusion élastique πd à 50 MeV sont en accord avec les prédictions des modèles qui incluent la partie P11 du potentiel πN intégral mais sont en désaccord avec ceux qui omettent ou suppriment cette composante.Measurements of the vector analyzing power in πd elastic scattering at 50 MeV are found to agree well with model calculations that include the full πN P11 potential and disagree when this is omitted or suppressed
