Simulation study of a silicon telescope
for ion identification @ HIE-ISOLDE
Detection system:
silicon DE detector 20 mm2, 30 (50)μm thick. Dead-layer: 100 nm silicon E detector 20 mm2, 600 (800) μm thick. Deadlayer: 700 nm Intrinsic resolution of the detectors: FWHM (MeV) = 8.94e-3 sqrt(E) to fulfill 20 keV at 5 MeV
Beam:
Ion beams of Li, Be, Mg, Al, Kr, Rb, Cs and Ba of different masses. Energy profile: gaussian with mean 5 (10) AMeV and
sigma 0.2% of the nominal energy. Beam spot: 2 mm diameter, perpendicular to the detector. 4e3 events simulated
