The Nobel Prize in Physics 1984
Carlo Rubbia, Simon van der Meer
Autobiography
I was
born in 1925, in The Hague, the Netherlands, as the third child
of Pieter van der Meer and Jetske Groeneveld, both of Frisian
origin. I had three sisters.
My father was a schoolteacher and my mother came from a teacher's
family. Under these conditions it is not astonishing that
learning was highly prized; in fact, my parents made sacrifices
to be able to give their children a good education.
I visited the Gymnasium in The Hague and passed my final
examination (in the sciences section) in 1943. Because the Dutch
universities had just been closed at that time under the German
occupation, I spent the next two years attending the humanities
section of the Gymnasium. Meanwhile, my interest in physics and
technology had been growing; I dabbled in electronics, equipped
the parental home with various gadgets and assisted my brilliant
and inspiring physics teacher (U.Ph. Lely) with the preparation
of numerous demonstrations.
From 1945 onwards, I studied "Technical Physics" at the University of
Technology, Delft, where I specialized in measurement and
regulation technology under C.J.D.M. Verhagen. The physics taught
in this newly created subsection of an old and established
engineering school, although of excellent quality, was of
necessity somewhat restricted and I have often felt regrets at
not having had the intensive physics training that many of my
colleagues enjoyed. 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.
After obtaining my engineering degree in 1952, I worked in the
Philips Research Laboratory, Eindhoven, mainly on high-voltage
equipment and electronics for electron microscopes. In 1956 I
moved to Geneva to join the recently founded European Organization for
Nuclear Research (CERN), where I have been working ever since
on many different projects, in an agreeable and stimulating
international atmosphere.
To start with, my work (under the leadership of J.B. Adams and
C.A. Ramm) was concerned mainly with technical design: poleface
windings, multipole correction lenses for the 28 GeV synchrotron
and their power supplies. 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. After working for a year on a separated antiproton
beam (1960), I proposed a high-current, pulsed focusing device
("horn") aimed at increasing the intensity of a beam of
neutrinos, then at the centre of interest at CERN and elsewhere.
The design of this monster, together with the associated neutrino
flux calculations kept me busy until 1965, when I joined a small
group, led by F.J.M. Farley, preparing the second "g-2"
experiment for measuring the anomalous magnetic moment of the
muon. I designed the small storage ring used and participated at
all stages of the experiment proper, including part of the data
treatment. This was an invaluable experience; not only did I
learn the principles of accelerator design, but I also got
acquainted with the lifestyle and way of thinking of experimental
high-energy physicists.
From 1967 to 1976 I returned to more technical work when I was
responsible for the magnet power supplies, first of the
Intersecting Storage Rings (ISR) and then of the 400 GeV
synchrotron (SPS). I kept up with accelerator ideas, however, and
worked (during my ISR period) on a method for the luminosity
calibration of storage rings and on stochastic cooling. The
latter was, of course, aimed at increasing the ISR luminosity,
but practical application seemed difficult at the time, mainly
because the high beam intensity in the ISR would have made the
cooling very slow. 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.
In 1976, Cline, McIntyre, Mills, and Rubbia proposed to use the
SPS or the Fermilab ring as a pp collider. Accumulation of the
needed antiprotons would clearly require cooling. 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). The successful
experiments in this ring and the work by Sacherer on theory and
by Thorndahl on filter cooling showed that p accumulation by
stochastic stacking was feasible. The collider project was
approved and I became joint project leader with R. Billinge for
the accumulator construction. Since then, I have worked with the
group that commissioned and improved the ring and that is now
preparing the construction of a second ring to increase the p
stacking rate by an order of magnitude. As a spin-off from this
work, I proposed the stochastic extraction method that is now
used (in a much improved form) in the Low-Energy Antiproton Ring
(LEAR).
In the meantime, in 1966, while skiing with friends in the Swiss
mountains, I met my wife-to-be Catharina M. Koopman and after a
very brief interval we decided to marry. This was certainly one
of the best decisions I ever made; my life has since been far
more interesting and colourful. We have two children: Esther
(1968) and Mathijs (1970).

In 1990 I retired from CERN.
