My interest in matters more directly concerned with the handling of particles was growing, in the meantime, stimulated by many contacts with people understanding accelerators.
At this time, my work on the SPS power supplies had just come to an end; I joined a study group on the pp project and an experimental team studying cooling in a small ring (ICE).
My father was a schoolteacher and my mother came from a teacher's family.
I visited the Gymnasium in The Hague and passed my final examination (in the sciences section) in 1943.
After developing a primitive theory (1968) I therefore did not pursue this subject. However, the work was taken up by others and in 1974 the first experiments were done in the ISR.
Nevertheless, if I have at times been able to make original contributions in the accelerator field, I cannot help feeling that to a certain extent my slightly amateur approach in physics, combined with much practical experience, was an asset.
