CERN Courier: July/August 2001

Cover of CERN Courier Volume 41 Issue 6

Sciencewatch

Cubic boron nitride could supplant diamond

A new material - cubic boron nitride (cBN) - could soon rival the status of diamond.

3-D printing is applied on a nanometre scale

New "soft lithographic" techniques, developed for fabricating structures at nanometre scales, could revolutionize this technology.

Transistors shed light on data transmission

Researchers at the National Institute of Advanced Industrial Science and Technology in Tsukuba, Japan, have developed a photonic transistor that uses a laser to control the amplification of signals in another laser beam.

Astrowatch

Observations of cosmic ripples reveal more hints of the blueprint for the early universe

April and May were exciting months for cosmologists, as new results brought them one step closer to unravelling the mysteries of the early universe.

European network for astro-particle physics is formed

Five European countries have pledged to collaborate on research into astroparticle physics.

Fermilab launches Run II of Tevatron

After detecting hints of the long-awaited Higgs particle, CERN's LEP electron-positron collider closed at the end of 2000 and is now being dismantled. The search for the Higgs - the missing link in today's picture of particle physics - is now taken up by Fermilab's Tevatron proton-antiproton collider, which has just begun a major new phase of operations. In this article, first published in Ferminews,* Mike Perricone sounds out the prospects.

A major SHIFT in outlook

The big experiments in high-energy physics are fertile ground for new developments in computers and communications - witness the World Wide Web, which was developed at CERN. Computer specialist Ben Segal recalls how distributed UNIX boxes took over from CERN's all-powerful IBM and Cray mainframe workhorses.

Isotope source hits target

The ISAC on-line isotope source at the Canadian TRIUMF laboratory recently achieved its full design energy. Paul Schmor and Jean-Michel Poutissou describe the experiments scheduled for the source.

Super Proton Synchrotron marks its 25th birthday

A quarter of a century ago, CERN's gleaming new Super Proton Synchrotron supplied its first proton beams. Although no longer the spearhead of CERN's research programme, the machine has become a vital part of CERN's unique interconnected accelerator network and continues to meet new challenges.

First African school for instrumentation

A recent instrumentation school held near Cape Town, South Africa, reflected the increasing worldwide appeal of fundamental physics. The first such school to be held on the African continent, it generated both positive feedback and pointers for new directions.

Lasers make light work

In May CERN Courier covered the Signatures of the Invisible art exhibition, which opened in London earlier this year and showcased the results of a collaboration between physicists from CERN and artists from around Europe. In this article, CERN technician Ian Sexton describes his encounter with an artist.
