Abstract
In 2014 the CEBAF electron accelerator at Jefferson Lab (JLab) will deliver a longitudinally polarized (up to 85%), high intensity (up to 100 mu A) beam with maximum energy of 12 GeV, twice the present value. To exploit the new opportunities that the energy upgrade will offer, a new spectrometer (Super BigBite - SBS) is under development, featuring very forward angle, large acceptance and ability to operate in high luminosity environment. The tracking system of SBS will consist of large area (40x150 cm(2) and 50x200 cm(2)), high spatial resolution (better than 100 mu m) chambers based on the GEM technology and 2 small (10x20 cm(2)) Silicon Strip Detector planes. The design of the GEM chambers and its sub-components such as the readout electronics is resented here.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
