The aim of this project is to develop high resolution tracking devices based on thin glass capillary arrays filled with liquid scintillator. This technique provides high hit densities and a position resolution better than 20 mu m. The radiation hardness of more than 100 Mrad makes capillary arrays superior to other types of tracking devices with comparable performance. The technique is attractive for inner tracking in collider experiments, micro-vertex devices, or active targets for short-lived particle detection in high-energy physics experiments. During 1996 and 1997, two prototype capillary bundles (1.8 m and 0.9 m in length) were put into operation. One of them was equipped with a conventional opto-electronic read-out chain and the other, for the first time, with a new device, the Electron-Bombarded CCD (EBCCD) imaging tube. The development of planar capillary layers is another aspect of the R&D activity. Details of the design and the performance are given.

Abstract
The aim of this project is to develop high resolution tracking devices based on thin glass capillary arrays filled with liquid scintillator. This technique provides high hit densities and a position resolution better than 20 mu m. The radiation hardness of more than 100 Mrad makes capillary arrays superior to other types of tracking devices with comparable performance. The technique is attractive for inner tracking in collider experiments, micro-vertex devices, or active targets for short-lived particle detection in high-energy physics experiments. During 1996 and 1997, two prototype capillary bundles (1.8 m and 0.9 m in length) were put into operation. One of them was equipped with a conventional opto-electronic read-out chain and the other, for the first time, with a new device, the Electron-Bombarded CCD (EBCCD) imaging tube. The development of planar capillary layers is another aspect of the R&D activity. Details of the design and the performance are given.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
