CERN Courier: October 1998

Cover of CERN Courier Volume 38 Issue 7

Astrowatch

Astrowatch

The universe is the ultimate particle physics experiment, and is a wonderful laboratory for effects which make terrestrial efforts seem puny. This new regular round-up of astronews will cover news and new developments in astronomy and astrophysics, with the accent on the physics.

SOHO back on track

After six weeks lost in space, the Solar and Heliospheric Observatory (SOHO) has been found. The $1 billion satellite was located when it reflected a signal sent into space by the Arecibo radio telescope in Puerto Rico.

First light at the VLT

Observations at Europe's Very Large Telescope (VLT) are off to a successful start. At the end of May, the first astronomical images were taken using the 8.2 m telescope. A second telescope will be installed this autumn.

Features

Cosmology comes of age

The easy part is over ­ experimental cosmology has now reached adulthood. That was the message that emerged from a workshop on cosmology and particle physics held at CERN this summer.

How Borexino will stare at the Sun

A new ultra-sensitive experiment to detect solar neutrinos is being built underground in Italy. As construction at the Gran Sasso laboratory nears completion, Gianpaolo Bellini explains how the Borexino experiment will work, and what it might tell us about the nature of neutrinos.

Nuclei as secret agents

Experiments with CERN's on-line isotope separator (ISOLDE) have led to a novel way to probe the interface between magnetic and non-magnetic ultra-thin layers.

Niels Bohr and the 20th century

The international "Niels Bohr and the Evolution of Physics in the 20th Century" meeting earlier this year provided the opportunity to reassess the evolutional impact of Bohr's "Lebenswerk".

Precision beams for hadron therapy

CERN is host to the Proton-Ion Medical Machine Study (PIMMS), a multinational collaboration that is looking at how particle physics can benefit medical treatment.

LEP helps fill CKM matrix

New evidence from CERN's Large Electron­Positron collider (LEP) sheds more light on the way quarks can transform.

QED: surviving the bad press

"How in the world can you make any money out of a theory like this?" asked Steven Weinberg. But quantum electrodynamics has proven a robust theory, and researchers are still pushing at its frontiers ­ as a workshop in Bulgaria revealed.

SLC perched on a high

The Stanford Linear Collider has generated its last Z particle ­ unless the US government provides more money. But it crowned its act with a flourish.

A hundred years ago...

In 1895, a chance discovery by Wilhelm Conrad Röntgen changed the face of science. It was the dawn of a new branch of physics ­ the investigation of subatomic phenomena. Following the centenary of the Röntgen discovery in 1995, an occasional series of articles in CERN Courier looks back at what happened one century ago.

Regulars

Faces and Places

More news from CERN and around the world of people and events of interest to the community.

The public and particle physics

The first of two articles in which, as his five-year mandate as Director-General of CERN nears its end, Chris Llewellyn Smith reflects on what particle physics has achieved, where it is going and why it deserves support.
