The G0 Detectors

The G0 detection system will consist of 8 "octant" detector modules. Each module includes individual detector elements (both focal plane (FPD) and exit window (CED) detectors), PMTs, and mechanical support. Four of the modules will be constructed by a North American collaboration consisting of Norfolk State (overall management), William and Mary and U. Maryland (scintillator fabrication), CMU (light guide fabrication), and U. Manitoba (PMTs, and bases) and JLab (octant support design). The remaining 4 modules will be fabricated by the French participating institutions (IPN Orsay or LPSC Grenoble). CEDs for both North American and French octants will be fabricated by the Louisiana Tech. Assembly and final testing will be carried out at JLab. A timing and gain monitoring system for all 8 octants will be provided by New Mexico State University.

A report on the status and technical design of the North American detector package design is currently in preparation. A draft outline as well as instructions for authors are available.

For the latest status report (as of December, 1998) on the detection system, see the appropriate section of the Report to PAC15. Earlier status information can be found in the Cost and Schedule Review Report. Additional information concerning details of the Detectors (mostly the North American detectors) is available below:
