Readout Modules for the Large Prototype

Drawings and images of the frames for the read-out modules can be found on Large Prototype web page of the Cornell University.
Several readout modules for the Large Prototype have been equipped with different gas amplification and read-out systems. They have been and are used for measurements in the electron testbeam T24/1 at DESY. Below you find some pictures and figures from these modules.
