The 12-GeV upgrade of Jefferson Lab’s CEBAF accelerator

The US laboratory accelerator is doubling its electron beam energy to address forces at work in protons and neutrons

| 9 June 2011

Why don’t quarks fly solo? Scientists have long observed that these particles, like Noah’s animals or instances of bad luck, always come in twos or threes. Yet nothing in the Standard Model of physics says quarks have to keep each other company. Scientists at Jefferson Laboratory in Newport News, US, will soon be uniquely positioned […]

SLAC scientists recover their systems at ATF

| 9 June 2011

KEK’s accelerator test facility, ATF, has many components installed on its beamline, many of which come from other laboratories around the world. From 21 May to 6 June, two scientists from the US laboratory SLAC, Janice Nelson and Glen White, came to ATF to check and recover systems that they are responsible for: the cavity […]

Present, future and science fiction of particle physics

New Humboldt professor Brian Foster takes office at DESY

| 2 June 2011

In June, Brian Foster will take up his work at DESY and University of Hamburg as a joint professor for experimental physics, with a focus on accelerators for very high energies. He is one of eight professors who won a Humboldt professorship this year, the most outstanding research prize in Germany, endowed with 5 million […]

Shin-ichi Kurokawa awarded Rolf Widerøe Prize

| 26 May 2011

The European Physical Society Accelerator Group announced that Shin-ichi Kurokawa, professor emeritus at KEK, Japan, and vice president of Cosylab, was awarded the Rolf Widerøe Prize, which is given to an individual for his or her outstanding work in the particle accelerator field. Kurokawa has been working in the accelerator field for 37 years. “I […]

A particle detector in space: interview with Maurice Bourquin from AMS

| 19 May 2011

When Maurice Bourquin participated in the first meeting between particle physicists and representatives of NASA in Houston, US, to understand the opportunity offered by the International Space Station (ISS) to support a particle physics experiment in space, he probably didn’t expect that his detector would finally fly 17 years later. A pioneer in the Alpha […]

The DHCAL expansion

New additions to the Digital Hadron Calorimeter expand the perspective through which scientists may view hadron showers.

| 12 May 2011

The CALICE collaboration’s calorimeter has grown a head and a tail. The Digital Hadron Calorimeter, or DHCAL, has acquired new active layers since scientists first began testing it last year. The additional layers, positioned at both the front and back ends of the detector, allow scientists to form more complete pictures of particle showers. “This […]

from CERN: LHC sets world record beam intensity

| 28 April 2011

Geneva, 22 April 2011. Around midnight this night CERN’s Large Hadron Collider set a new world record for beam intensity at a hadron collider when it collided beams with a luminosity of 4.67 × 1032 cm-2s-1. This exceeds the previous world record of 4.024 × 1032 cm-2s-1, which was set by the US Fermi National […]
