Silicon Vertex Tracker

The Silicon Vertex Tracker (SVT) portion of the CLAS12 detector at Jefferson Lab is intended to recreate the trajectories of charged tracks with angles between 35 and 125 degrees. It will include nearly 34,000 channels of silicon strip sensors in eight layers (four regions).

Layout
Each layer of the SVT includes 256 strips with linearly varying angles of 0 to 3 degrees.

The sensors have a graded angle design to minimize dead areas have and a readout pitch of 156 μm. The SVT will be centered inside the superconducting solenoid.

Other
The single-sided microchip sensors in the SVT are created by Hamamatsu Corp. of Japan.
