International Linear Collider (Detector Development)

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.

Pixel Vertex Detector

The ILC detector will need to reconstruct decay vertices that are displaced by small amounts from the collision point. One candidate technology is a pixel detector using Silicon on Insulator (SOI) technology. SOI integrates pixel sensors and readout circuitry into a single "monolithic" unit, offering higher speeds and lower power consumption than bulk CMOS devices. Our group at Cornell is simulating these devices to investigate effects such as charge coupling and to guide the design of detectors.

Time Projection Chamber Tracker


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

Cornell is developing Time Projection Chamber technology for the ILC. We have built a small prototype equipped with interchangeable readout sections and an instrumented ion-collection plane to compare the performance of GEM, MicroMegas and traditional pad readout.

Cornell is also a part of LC-TPC, an international collaboration that is building a large-scale prototype. The Cornell contribution to the large prototype is the endplates


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

We are developing TPC digitized signal simulation and event reconstruction software.
