The multiplying effects of an accelerator economy

| 3 November 2011 A company in Lansing, US is developing accelerator cavities for the ILC. In the course of improving these high-tech devices, it has enhanced its expertise in developing them for other areas of science and, as an added benefit, sustaining the technology R&D.

Onward and upward into the terascale

| 20 October 2011 Until the Large Hadron Collider tells scientists where in the energy frontier to dig for new physics, ILC researchers are preparing for eventualities. Should new physics be found to reside in a range higher than the ILC’s current reach, scientists have a energy-boosting plan in their back pocket. Category: Feature | Tagged: , ,

CERN balances linear collider studies

| 13 October 2011 Steinar Stapnes has assumed the title of CERN’s Linear Collider Study Leader, a newly configured position that acknowledges a call for cooperation between the ILC and the laboratory’s well established Compact Linear Collider study. His new post requires him to perform a balancing act that involves two collider concepts, roughly a hundred researchers and a finite number of Swiss francs. Category: Feature | Tagged: ,

Going with the particle flow

| 15 September 2011 Resolved that pictures of particle jets don’t have to be fuzzy or gnarled, scientists developed the particle flow algorithm, a paradigm for effectively teasing out each particle’s energy from another’s. To make it work, researchers expanded the tracking capabilities of the detector model, enabling it to measure energies with higher precision. Category: Feature | Tagged: , , ,

Seeing beneath the surface

| 1 September 2011 Accelerator cavities have their faults, and some pits and cracks hide deep in the walls or in out-of-the-way places where they aren’t easily found. Accelerator researchers help improve flawed cavities by taking their fault-finding missions beneath the cavity surface with X-ray computed tomography. Category: Around the World | Tagged: , ,

Detector scientists and the chamber of GEMs

| 18 August 2011 Being holed up at Fermilab's Test Beam Facility for two weeks, 18 hours a day is no reason to go hungry. Researchers from the University of Texas at Arlington subsisted on instant noodles while they kept busy with their gas electron multipliers, one of the technologies being developed for the ILC detector.

The fruits of industry

| 11 August 2011 The R&D of industry is as vital to the ILC project as research performed in the laboratory. The Global Design Effort has formed close relationships with multiple industry vendors, fostering innovation and reducing costs. Category: Feature | Tagged: , ,

Good gradients in seconds flat

| 4 August 2011 A stable particle beam needs a trouble-free path on its way to high energies, and that means providing it with a smooth gradient to ascend. A team of scientists at Fermilab has arrived at a way to control accelerating cavities so they can give particle beams exactly that – a tilt-free path to collision.

Power to the cryomodule

| 28 July 2011 Cryomodule 1 at Fermilab is now being powered as a complete, multi-cavity instrument. Scientists will subject it to superconducting radiofrequency tests over the coming weeks. Category: Around the World | Tagged: , ,

Achieving cavity resonance

| 7 July 2011 Keeping accelerating cavities tuned to the right frequency requires continual, gentle hammering by a little device called a piezoelectric tuner. DESY scientists have mastered the art and science of applying the piezo to cavities, bringing them to within several ten-thousandths a percent of the desired frequency.
