New CALICE calorimeter sees beam

| 31 May 2018 Particle physics will always need calorimeters, so particle physicists are always trying to optimise, tweak and update their calorimeter systems for the best possible measurements. The CALICE collaboration plays a leading role in this, and their most recent prototype for a hadronic calorimeter has just been completed and is now at CERN for a round of tests in the test beam.

Detector experts meet in Ichinoseki

| 5 April 2018 The planners and builders of the future ILD detector met in Ichinoseki, close to the potential future home of their high-tech masterpiece, in February to compare notes and advance the detector design. Category: Around the World | Tagged: , , , , , ,

Gearing up to final form

| 14 December 2017 Sometimes a neat line of dots on a computer screen can stand for that moment when it all comes together. A reward for years of hard work, many meetings, lots of travel and nights spent in test beam huts. At least that’s the case for a team of physicists and engineers who have spent the last years designing and testing detector components for a future linear-collider detector, the Silicon-Tungsten electromagnetic calorimeter or SiW-ECAL. During a recent test campaign at the German research lab DESY the developers came together to probe their latest detector design together with the latest sensors and all components that have been developed over the last years.

Let them collide!

| 16 February 2017 This animation, created by Rey.Hori, shows what happens when electrons and positrons collide in the ILD detector, one of the planned detectors for the future ILC. Many collisions will happen at the same time around the clock, producing a vast array of possible processes, or events. This animation shows the example of one possible collision event involving the Higgs boson. Here’s a guide to what happens in the clip.

Pandora: opening the box for neutrino experiments

| 16 February 2017 Pattern recognition rules in particle physics. When particles collide, many things happen at the same time and in a very fast sequence within fractions of a second. In order to tell everyday events from rare ones, particle physicists use pattern recognition software to quickly scan and classify pictures from the collisions.

Calorimeter under telescope scrutiny

| 3 November 2016 While the CALICE collaboration is still busy analysing the data taken at last year’s big test campaign the team planning the hadronic calorimeter for the ILD detector are already gathering new data. This time they looked at the performance of a few prototype layers in a test beam connected to a beam telescope. Category: Around the World | Tagged: , , , , , , ,

See you, summer students

| 8 September 2016 Summer is drawing to a close, and with it ends another season that often turns lab life on its head and has changed many people’s lives: summer student season. As the students from around the world finish off their projects, present their work to their fellow students and stock up on lab t-shirts, some leave with the certainty that they will return to do particle physics one day.

Gotta catch them all – and fast

| 22 July 2016 Silicon detectors play a crucial role in particle detectors, both present experiment at the LHC and future experiments like the ILC. More than 80 calorimeter and silicon tracking experts attended a dedicated workshop on high-granularity silicon devices, held last month in Hamburg.

Tunnel visions for civil engineers

| 7 July 2016 A delegation from the Japan Society of Civil Engineers including its president took to Europe last month to have a look at civil engineering project for large science facilities. They visited CERN and DESY to look at past and current building projects, which they would use as a reference in case ILC is constructed in Japan. Category: Around the World | Tagged: , , , ,
