International Linear Collider

Experimental Particle Physics

The International Linear Collider is an electron-positron collider with an initial collision energy of 500 GeV, upgradable to 1 TeV. It will explore the TeV energy scale, shedding light on the physics that lies there. It will complement, and build upon, the discoveries of the LHC.


A prototype Time Projection Chamber (TPC) used to study different readout schemes.

Cornell is developing TimeProjectionChamber technology for the ILC. We have built a prototype equipped to compare the performance of GEM, MicroMegas and traditional pad readout. Cornell is also involved in planning for a large-scale international prototype.

We are also developing TPC reconstruction software.


A sample event, e+e- -> ZH, in the LCD candidate detector illustrates the complications from overlapping tracks.

Cornell is also studying the Silicon-on-Insulator option for a pixel vertex detector for the ILC. Silicon-on-Insulator, a technology that integrates pixel sensors and readout circuitry into a single "monolithic" unit, is a potential candidate for the ILC pixel detector. Our group at Cornell is simulating these devices to investigate effects such as charge coupling and guide the design of detectors.

Cornell has done simulations of physics that can be done at the International Linear Collider. In one Focus Point study, we have examined the characteristics of certain Supersymmetric particles that may constitute the Cold Dark Matter of the universe.
