CLEO-II Silicon Vertex Detector

The CLEO-II silicon vertex detector is a particle detector, used to make very precise reconstruction of the trajectories of charged particles that are produced in electron-positron collisions. When complete, the device will be installed in the CESR electron-positron storage ring at Cornell University in Ithaca, New York.

The research for, design of, construction of, and exploitation of this device in particle physics research is the result of a collaboration of institutions including Caltech, Cornell, Harvard, Illinois, IPP, Oklahoma, OSU, Purdue, and UCSB. The device itself is under construction at UCSB. The UCSB team includes Kirk Arndt, Anton Eppich, Jeff Gronberg, Klaus Habermeier, Dave Hale, Chris Korte, Susanne Kyre, Rolly Morrison, Tim Nelson, Karl Runde, Hiro Tajima, and myself.

More information on the project can be found here .


These are a schematic, and a parameter table, for the device:

An Octant

These are color photos of the first 1/8 of the device, known as an octant:

Our colleagues at the Wilson Lab has taken data from the device in the pictures above, with cosmic ray muons. Here are displays of an event:

Octants in the Clamshell

These are snapshots, taken on 12/9/94 and 12/12/94 with a polaroid camera, of the installation of octants into the supporting half-cylinder, known as the clamshell:
