Micro-Gap chambers with self-aligned geometry

As the high abstention rate during the last european election shows, it seems that a large part of the european population is rather sceptical towards the european integration process. One ascribe this "euroscepticism" to the European Union communication. Our paper aims to evaluate this hypothesis which is not as obvious as it seems first. To do so we have evaluated the communication policy which as been set up by the European Commission (before the Romano Prodi Presidence) to conclude that the lack of a real european public sphere is probably a better explanation of this phenomenon

Assembly and validation of the SSD silicon microstrip detector of ALICE

The Silicon Strip Detector (SSD) forms the two outermost layers of the Inner Tracking System (ITS) of ALICE. The SSD detector consists of 1698 double-sided silicon microstrip modules. The electrical connection between silicon sensor and front-end electronics is made via TAB-bonded aluminium polyimide cables (chip-cables). The module assembly is challenging because of the module geometry and the use of chip-cables. This article describes the assembly procedure and the test protocol used

The ALICE vertex detector: Focus on the micro-strip layers

The ALICE experiment, which is being installed at the Large Hadron Collider at CERN, is designed to operate in a high-track density environment which is typical of relativistic heavy ions physics. This paper reports the main characteristics of the Inner Tracking System (ITS) of ALICE and describes the Silicon Strip Detector, which forms the two outermost layers of the IT
