Designing and fabricating an optimal accelerating cavity is not so simple. There are two important parameters scientists are looking for: the gradient of 35 megavolts per meter (MV/m) and the quality factor (Q0) of greater than 0.8×1010. A Japanese cavity now fulfilled those requirements for the first time at a test which took place at […]
It’s particle showers in a tungsten hadron calorimeter
Even though last week’s “What is it?” does show recent test results it is not an image of temperature mapping of a cavity, sorry. Guest author and calorimeter expert Frank Simon explains what we really see: The “What is it?” image of last week’s ILC NewsLine is a picture-perfect example of why we now often call […]
Linear collider scientists tour the Mont Blanc tunnel
Tiny particles, producing brilliant collisions as they race around an underground tunnel, are the stars of an accelerator. It’s easy to forget that people, too, must make their way around the tunnel, and that their protection merits as much attention as do flying bits of matter. A group of scientists and engineers at the International […]
The future city of the ILC
What will happen when the ILC is built? One hopes discoveries will change the way we see the universe. It will answer the questions about what the universe is made of. And maybe it will help generate new Nobel Prize winners… “OK, I understand that something great will happen in the academic world. But I […]
Jefferson Lab’s rules for achieving spotless cavities
Depending on your household’s rules of cleaning, you may have learned about a “right way” to wash dishes: keep dishwater clean for as long as you can, cleaning glasses first, then silverware, then plates. Save the dirtiest wares, pots and pans, for last. Jefferson Lab technician James Davenport carefully inserts a cathode into an ILC […]
You say you want more resolution…
Scientists led by a group at Argonne National Laboratory are bringing pictures of hadronic showers into sharper focus with the Digital Hadron Calorimeter, or DHCAL, one of several hadron calorimeter options for the ILC detector. The Argonne group began testing the device last month at the Fermilab Test Beam Facility. The new particle detector makes […]
Geneva part 2
As the first in a planned series of workshops, the International Workshop on Linear Colliders had many accomplished missions on the agenda. The ILC, for example, has passed its self-imposed fifty percent mark: half of the nine-cell superconducting radiofrequency cavities produced in the world now reach the desired gradient. The Compact Linear Collider Study (CLIC) […]
Live from Geneva
For the first time in a meeting of this scope, this year’s International Workshop on Linear Colliders in Geneva, Switzerland, brings together researchers from both of the world’s major linear collider projects: the International Linear Collider and the Compact Linear Collider. Organised by the European Committee for Future Accelerators, the conference is held at CERN […]
From interactions: DESY and TRIUMF take home top prizes from the first Global Particle Physics Photowalk
14 October 2010 – A sunburst image of a particle detector at Germany’s DESY laboratory and a black-and-white photograph of a nuclear-physics experiment at TRIUMF in Canada have won the top prizes in the first-ever Global Particle Physics Photowalk. More than 100 of the top photographs from the photowalk, including the six winners of the […]
Your chance to influence the Project Design Guidance
At the end of 2012, the Global Design Effort (GDE) will release its Technical Design Report. At the same time, the Research Directorate (RD) and the ILC community will produce detailed baseline designs for two detectors. What then? A conceptual supporting model of a multinational-laboratory This is the question being addressed by the International Linear […]
