Common ground in ILC and CLIC detector concepts

| 22 August 2013 The Compact Linear Collider and International Linear Collider will accelerate particles and create collisions in different ways. Nonetheless, the detector concepts under development share many commonalities. Category: Feature | Tagged: , , , , ,

Particle flow

| 18 April 2013 With the help of the particle flow algorithm, physicists will be able to identify and measure each particle of a collision using the subdetector which provides the best measurement. LCpedia explains. Category: LCpedia | Tagged: , ,

An eye on the pulse

| 6 December 2012 The technical prototype of the silicon-tungsten electromagnetic calorimeter, one of the calorimeter options for the ILC’s ILD detector, is about to spend its first weeks in a test beam at DESY. The team will test its performance under power-pulsed operation and take detector development one step further towards a real collider detector. Category: Around the World | Tagged: , , , , , , , ,

From CERN Bulletin: From calorimetry to medical imaging: a shining example of successful transfer!

30 August 2012 A team at CERN has drawn inspiration from calorimetry methods developed for high-energy physics to create a new positron-emission tomography system for use in medical imaging, which they’ve dubbed AX-PET. With support from European and American laboratories, the project is reaching fruition, as initial tests confirm its promise. Category: Around the World | Tagged: , , , ,

Large-scale powering scheme has scientists’ pulses racing

Images: IPNL | 17 May 2012 For the first time, a large-scale calorimeter prototype for the ILC, fully equipped with embedded power-pulsed electronics, successfully passed a test beam at CERN a few weeks ago. A prototype of more than one cubic metre in size of CALICE’s Semi-Digital Hadronic Calorimeter successfully recorded and tracked 1 million particles from CERN’s SPS accelerator beam (muons and pions). Thanks to power pulsing, the detector front-end electronics was periodically disabled and enabled, following the beam cycle. Read more and view more photos about the test beam.

The science of showers

| 12 January 2012 Good timing is a virtue. Just as comedians have to wait for just the right moment to deliver their punch line, linear collider physicists need to know when to make cuts. These cuts separate phenomena called particle showers from each other, making it possible for the physicists to tell which reaction originated from which collision. Two German PhD students have built a test device that is supposed to get behind the precise timing of showers. Category: Profile | Tagged: , , , ,

The impact of ILC detector R&D

| 18 August 2011 Although the actual construction date of the ILC accelerator and its detectors is very uncertain, the impact of the R&D for ILC detectors is very real. Sometimes we tend to overlook the deep impact the work initiated by and carried out within the ILC detector community has already had on the whole particle physics community and beyond.

Linear collider technology in your body

| 20 January 2011 A device used the linear collider’s hadronic calorimeter could soon help detect cancer. It would also be the central part of what is likely going to be the world’s smallest calorimeter – so tiny that it can fit on the tip of an endoscope to be inserted into a person’s stomach. Since January 2011, a consortium of some 60 scientists from 13 institutes all across Europe is officially building the world’s first in-body calorimeter, funded by the European commission in its 7th Framework Programme with about 6 million Euros over a period of four years.

CALICE gathers forces to design the calorimeters of the future

| 27 September 2007 The CALICE (Calorimeter for Linear Collider Experiment) collaboration is growing and anticipating the future of ILC calorimeters. The members not only prepare test-beams for the current generation of calorimeter prototypes, but they also prepare the future design of ILC sub-detectors. A record number of 72 CALICE members reviewed and discussed all these aspects two weeks ago in Prague during a collaboration meeting. Category: Feature | Tagged: ,
