A new hybrid silicon μstrip and large area GEM (Gas Electron Multiplier) tracker is under development for the upcoming high luminosity (up to 1039 /s/cm2) experiments at the Hall-A of the JLab 12 GeV electron beam facility. The system consists of 2 small 10×20 cm2 silicon planes placed near the scattering chamber and 18 40×50 cm2 GEM modules that form larger chambers with variable active area depending...
In 2014 the CEBAF electron accelerator at Jefferson Lab (JLab) will deliver a longitudinally polarized (up to 85%), high intensity (up to 100 μA) 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...
The crate service card (CSC), has been designed and built to complete the readout of the instrumented flux return (IFR) of the BABAR experiment at the Stanford Linear Accelerator Center (SLAC). The CSC, which is physically part of the on-detector electronics, implements the slow control interface between the front end cards (FECs) and the IFR on-line detector control system (IODC). It broadcasts the...
