Nomination of Alex Chao
Representative publications
#1 A. W. Chao and J. Gareyte, “Scaling Law for Bunch Lengthening in SPEAR II”, SLAC Report
SPEAR-197/PEP-224 (1976), journal reprinting Part. Accel. 25, 229 (1990).
The Chao-Gareyte Scaling clarified the physical process of the anomalous bunch lengthening effect
observed in electron storage rings.
#2 Alexander W. Chao, “Evaluation of Beam Distribution Parameters in an Electron Storage
Ring”, J. Appl. Phys., Vol.50, No.2, 595 (1979).
This paper invented a concise and elegant way to calculate the beam distribution parameters in an
electron storage ring. It is the only way to do such calculations for an accelerator with coupled
lattice in 6-D phase space. It also paved the way to the realization of the possibility of the next paper
#3.
#3 Alexander W.Chao, “Evaluation of Radiative Spin Polarization in an Electron Storage Ring”,
Nucl. Instru. and Meth. 180, 29 (1981).
This paper invented an elegant technique for polarization calculation in electron storage rings. The
technique clarified the physical process of radiative polarization, and provided a correct way to
calculate polarization. It was later implemented in a program SLIM, which became a standard tool
for polarization calculations.
#4 Alexander W.Chao and Kaoru Yokoya, “An Alternative Longitudinal Polarization Scheme for
TRISTAN”, KEK Report 81-7 (1981).
The Chao-Yokoya Spin Transparency Conditions played a crucial role in the design and the
understanding of longitudinal polarization in electron storage rings such as HERA in Germany or
the Tau/Charm factories.
#5 Alexander W.Chao, Burton Richter, and Chi-Yuan Yao, “Beam Emittance Growth Caused by
Transverse Deflecting Fields in a Linear Accelerator”, Nucl. Instru. Meth. 178, 1 (1980).
This paper pioneered the study of beam-break-up instability for high-intensity linear colliders.
Beam-break-up instability is the basic effect that limits the performance of linear colliders.
#6 Alexander W. Chao, “Coherent Instabilities of a Relativistic Bunched Beam”, US Summer
School on High Energy Particle Accelerators, SLAC, AIP Conf. Proc. 105 (1982) p.353.
This article was an acknowledged reference on the subject. It was later expanded into a book
“Physics of Collective Beam Instabilities in High Energy Accelerators”, John Wiley & Sons, New
York, 1993. It is the classic book reference on this topic.
#7 A.W.Chao and R.D.Ruth, “Coherent Beam-Beam Instability in Colliding Beam Storage Rings”,
Part. Accel. 16, 201 (1985).
Chao wrote a series of papers which led the research avenue of coherent beam-beam effects. This
view of the beam-beam effect (that limits the performance of storage ring colliders) was
revolutionary at the time but has now become a standard vocabulary.
#8 SSC Central Design Group, “Superconducting Super Collider Conceptual Design”, SSC-SR2020 (1986). Chao wrote Chapter 4.
This was the design base of the project Superconducting Super Collider. Its completion represented
a team work of many accelerator physicists.
#9 A. Chao et al., “Experimental Investigation of Nonlinear Dynamics in the Fermilab Tevatron”,
Phys. Rev. Lett. 61, 2752 (1988).
This was the first study of nonlinear dynamics as formal experiment using accelerators. The results
had impacted the way these experiments are carried out in later years.
#10 “Handbook of Accelerator Physics and Engineering”, Editors Alexander Wu Chao and Maury
Tigner, World Scientific, Singapore, 1999.
This 650-page handbook is a concise summary of more than 200 world’s top experts on a wide
range of accelerator topics. This was an ambitious project and is used widely by practitioners in the
field.
#11 Alexander W. Chao and Ernest D. Courant, "Spin Echo in Synchrotrons", Phys. Rev. Special
Topics - Accelerators and Beams 10, 014001 (2007).
This paper proposed an exciting spin dynamical effect called spin echo. The mechanism results from
an intricate interplay of spin dynamical phase space. Experiments are being designed to test this
theoretical prediction. This work. together with the understanding in spin dynamics that comes with
it, have large implications for the polarization community in high energy physics.
#12 Alexander W. Chao, "Gravitational Instability of a Nonrotating Galaxy", J. High Energy and
Nuclear Physics, 2005.
This insightful paper predicts a size of galaxy beyond which the galaxy becomes unstable. Results
agree well with astrophysical observations. This paper is an application of sophisticated techniques,
developed to analyze beam instability problems in accelerator physics, to the problem of galaxy
instability in astrophysics.
#13 Alexander W. Chao, "Matrix formalism for spin dynamics near a single depolarization
resonance", Phys. Rev. Special Topics – Accelerators and Beams 8, 104001 (2005); "Experimental
test of the new analytic matrix formalism for spin dynamics", V.S. Morozov et al, Phys. Rev.
Special Topics - Accelerators and Beams 10, 041001 (2007); "Experimental verification of striking
predicted oscillations near a spin resonance", V.S. Morozov, et al., submitted to Phys. Rev. Lett.
(2007).
These 3 publications address a striking interference phenomenon of spin dynamics. The first paper
was theoretical, and the next two are experimental results beautifully confirming the theoretical
predictions.
