摘要：

The ALICE Silicon Pixel Detector (SPD) is constituted by two barrel layers with approximate to 10' hybrid pixel cells. The basic detector element is the Half-Stave (HS), an array of two ladders, each composed of 5 pixel chips bump bonded to a Si sensor matrix. The ladders are mounted on a low-mass aluminum/polyimide multilayer bus for power distribution and signal routing. The assembly procedures of the half-staves and their mounting on the carbon fiber support sectors, implemented on high precision measuring tables, with computerized controllers for positioning and gluing, are described, and the present status of construction is overviewed.
