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.

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.

Working together on Linear Collider software tools

and | 14 December 2017 In order to understand particles you need the right software. Analysing the functionality of your detector, predicting how particles interact and how they move through the detector parts and reconstructing what happened during a collision all depend on the right software. This software isn’t available in app or play stores – if you want it, you have to write it yourself. The linear collider community has recently brought its software up to scratch.

German teachers get a taste of ILC R&D

| 23 November 2016 Teachers in the test beam! ILC cavitiy testing and test beam life played a major role at a recent teacher training held at DESY. It was the first time that the German lab invited high school teachers for a week focused on particle physics. Category: Around the World | Tagged: , , , , , , , ,

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.

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: , , , ,

From metal sheet to particle accelerator (part 3 of 3)

| 12 May 2016 If you're an electron, a ride in a cavity is pretty much the coolest thing that can happen to you. If you're an accelerator and you need huge numbers of cavities you better make sure they're all of outstanding quality – which is what the X-ray free-electron laser European XFEL under construction in Hamburg has just finished. In a series first published in DESY inForm, we look at how a niobium sheet turns into a curvy beauty. Part three describes how they make their way from test benches into the cryomodules and, finally, into the tunnel. Category: Around the World | Tagged: , , , , , , ,

From metal sheet to particle accelerator (part 2 of 3)

| 28 April 2016 If you're an electron, a ride in a cavity is pretty much the coolest thing that can happen to you. If you're an accelerator and you need huge numbers of cavities you better make sure they're all of outstanding quality – which is what the X-ray free-electron laser European XFEL under construction in Hamburg has just finished. In a series first published in DESY inForm, we look at how a niobium sheet turns into a curvy beauty. Part two describes the series of tests cavities have to undergo before making their way into an accelerator module. Category: Around the World | Tagged: , , , , , ,
