High resolution tracking devices based on capillaries filled with liquid scintillator

We propose to develop high resolution tracking devices based on thin glass capillary arrays filled with liquid scintillator. This technique provides high 182 hit densities and position resolution better than 20 microm. Further, their radiation hardness makes them superior to other types of tracking devices with comparable performance. Therefore, the technique is attractive for inner tracking in collider experiments, microvertex devices, or active tar gets for short-lived particle detection. High integration levels in the optoelectronics readout based on the use of Electron Bombarded CCD (EBCCD) and the possibility of optical multiplexing reduces the number of output channels and, thus, the cost for the detector considerably. Moreover, development of good time resolution Vacuum Image Pipeline (VIP) will allow the use of this technique in high rate environments. The programme of an intense R&D effort on the above subjects is described.
