摘要
The central part of the AMS detector is occupied by the silicon tracker. It is built out of 2264 double-sided silicon microstrips sensors, 51.36 x 72.05 x 0.30 mm(3) each, with a total surface of 6.7 m(2). The sensors are combined into ladders of 7 to 15 sensors and the ladders disposed onto eight layers installed inside a superconducting magnet with bending power of 0.8 Tm-2. To evacuate the heat generated by the tracker electronics in the vicinity of the superconducting magnet cryostat, a two-phase mechanically pumped loop system with carbon dioxide (CO2) has been developed. A detailed description of the whole tracker system will be presented.
