The DHCAL expansion

| 12 May 2011 The Digital Hadron Calorimeter offers high-resolution images of particle showers. With the help of hundreds of thousands of readout pads, tiny pieces of each charged particle’s path within hadronic showers are recorded. The DHCAL brings scientists not only detailed images, but now also complete ones, having expanded its potential in recent months by tens of thousands of additional readout channels.

from CERN Courier: Inside Story: The discovery of superconductivity

5 May 2011 One hundred years ago, on 8 April 1911, Heike Kamerlingh Onnes and his staff at the Leiden Cryogenic Laboratory were the first to observe superconductivity. In a frozen mercury wire, contained in seven U-shaped capillaries in series, electrical resistance suddenly seemed to vanish at 4.16 K. Category: Feature | Tagged:

from DESY inForm: No resistance

5 May 2011 These are the electrifying moments to make a scientist’s life worth living: take up work at a laboratory, carry out measurement series and, suddenly, see absolutely unexpected results – a tiny detail which is wrong. The measurements are repeated and tested for possible mistakes – but the unexpected proves true. Category: Feature | Tagged:

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 Accelerator Laboratory’s Tevatron collider in 2010, and marks an important milestone in LHC commissioning.

KEK continues to work for the ILC

| 7 April 2011 Atsuto Suzuki, director general of KEK in Tsukuba, Japan, states that despite the devastating earthquake and tsunami that hit Japan on 11 March, no changes have been made to KEK’s ILC-related plans. Category: Feature | Tagged: , , ,

A day in a particle physicist’s shoes

| 31 March 2011 March is particle hunting season for more than 8,000 students who participated in the International Hands on Particle Physics Masterclasses. And this year features a premiere: they analyse real high-energy proton collisions from 2010’s events at the Large Hadron Collider. Category: Feature | Tagged: , , ,

Physics slam has real impact

| 31 March 2011 Eugene, Oregon played host to the first-ever physics slam in the United States. By all accounts, it was a runaway success. Category: Feature | Tagged: , , ,

KEK earthquake report

| 17 March 2011 As many people in the world already know, Japan is currently dealing with its worst disaster: Japan's biggest earthquake on record and the fourth largest in history. Thousands of lives have been lost. Tens of thousands people are forced to evacuate and live without basic necessities. Hundreds of thousands are still missing. Category: Feature | Tagged: , ,
