From Cornell Chronicle: Cornell electron storage ring is test case for International Linear Collider
Mark Palmer, research associate at CESR, explains the goals of CesrTA. |
Scientists working on the proposed International Linear Collider (ILC) know exactly what they want it to do -- collide tightly focused beams of subatomic particles with unprecedented energy, recreating conditions during the big bang and unlocking the mysteries of the universe's origins.
Exactly how to do that is another story.
Still in early stages and several years away from being built, the ILC is garnering key design insights from Cornell scientists, who are creating a prototype of a major ILC component called a damping ring. The two-year project, which involves reconfiguring Cornell's existing electron storage ring (CESR) into a damping ring, is called CESR Test Accelerator (CesrTA).

From football field to field strengths
Construction starts for XFEL accelerator module test facility
In the accelerator module test facility that is being built at DESY for the European XFEL, three modules can be tested side by side. |
It takes vision to be able to image the transformation of one thing into another. Take a football field, for example. What are your associations – running, competition, goals, fun? And now imagine you want to build a new accelerator. What would you use the field for? The European XFEL team at DESY did not have to reflect for very long: acceleration, competition, goals? An accelerator module test facility of course! It’s only a small step to the next vision: an accelerator module test facility for the ILC…

Dark Energy: Still a Puzzle
...That is, they can cook up a result for distance vs. redshift in this model that looks like it would in a smooth model with dark energy, even though there’s nothing but ordinary (and dark) matter in their cosmology.

Keeping up with ILC technical progress
The cover page of the latest Project Managers' monthly report |
One of my major challenges in writing this weekly column is tailoring it to an audience that ranges from scientifically interested outsiders to technical experts who are members of the Global Design Effort. From the recent ILC NewsLine survey we know that our audience is about evenly split between these constituencies and we try to balance the content accordingly. In this column, I also try to provide more general context and perspectives related to the ILC. Today, I want to advertise another useful resource that provides detailed ILC technical developments: the monthly Project Managers' Report.
