From Symmetry Breaking: Rewriting textbooks and remeasuring the particle data booklet at the LHC

Theorist Hitoshi Murayama's prediction for a page in the PDG in 2016.
Textbooks were being rewritten during last week’s Physics at LHC conference.

“I was sitting in the session, listening to the ALICE talk by Andrea Dainese from Padova on Wednesday morning, and suddenly I knew: I could replace all the textbook bubble-chamber pictures from the sixties in my lectures,” said DESY’s Thomas Naumann, a member of the ATLAS collaboration.

Feature Story
The ILC, a very special market for high purity niobium

First 9-cell cavities manufactured by Hitachi, Ltd (front) and Toshiba, Inc. (rear) as manufacturing studies for ILC in Japan coordinated by KEK, in addition to the already ongoing efforts by Mitsubishi Heavy Industries, Ltd. Image: Nobu Toge
The ILC will have an ultra-cold and complex heart made of niobium, a rare, soft, grey, and ductile transition metal. Some 18,000 radio frequency (RF) accelerating cavities for the ILC will be made of niobium, which becomes superconductor when cooled to nearly absolute zero.

The global annual production of niobium in 2007 was 58,000 tonnes, and it is expected to grow up to 45 percent more in 2010 with a positive trend towards economic recovery. Although it is a 'rare' material, the reserves of niobium are assumed to be enough to cover the current world demand for 500 years – well enough to supply the ILC cavities and many other projects which uses or will use niobium-based superconducting RF systems...

Indian women in science
Following ILC NewsLine special issue of 3 June featuring Women in science, we received a short letter from Abhay Deshpande (KEK) mentioning Indian programmes and associations for Indian women scientists and engineers.

From the Indian perspective, there are many more issues when it comes to encouraging women to follow science, for that matter any career path. Fortunately, researchers in India realised this quite at an early stage and we have a good forum as well. May I introduce you " Women in science, an Indian Academy of Science initiative". They have published a book called "Daughter's of Lilavati" which is very well received. Professor Rohini Godbole, convener for ILC in India is a member of the "Panel on Women in Science". We also have an active Women Scientists' Association in India.

Crafting the World's Smallest Beam
"That minuscule beam is needed for next-generation colliders including the International Linear Collider and the Compact Linear Collider. Packing more electrons and positrons into a thinner beam makes it more likely that individual particles will collide, increasing the number of collision events recorded."

Race for knowledge spurs physics research at CERN
"The Large Hadron Collider is coming late to the party and has a lot to prove in the particle physics community. It's no surprise then that a little competitive jockeying plays a role in CERN's research strategy."

Celebrating the fiftieth anniversary of the laser

This year we are celebrating the 50th anniversary of Theodore Maiman's demonstration of the first working laser at Hughes Research Laboratory in 1960. The laser has become so common that what began as an acronym describing a physics phenomenon (LASER for Light Amplification by Stimulated Emission of Radiation) is now commonly understood noun worldwide. In the English language, it is defined in the Compact Oxford English dictionary as: "laser: a device that generates an intense narrow beam of light by stimulating the emission of photons from excited atoms or molecules." The development of the laser from a fundamental physics discovery to a multibillion-dollar industry and its pervasive and unforeseen impacts on how we live, make a very powerful case for the value of basic research.
