High space and time resolution detectors based on position-sensitive photomultipliers

Obiettivo



The aim of this research project is the development of high space and time resolution detectors using scintillating fibres (SciFi) and position-sensitive photomultipliers (PSPM).

The groups involved have extensive experience and have worked in this field for several years with excellent results. Members of these groups have participated in international R&D collaboration in the field of SciFi+ PSPM detectors for high-energy experiments, based on original research pioneering conceptual and technological development for modern PSPM based on grid-dynode structures. The NIS group at IHEP (Protvino) has also for a long time been developing PSPMs of another (linear) type with a Russian firm (MELZ). The INP group in Novosibirsk, where a specialised photomultiplier laboratory has been active for many years, intends to develop PSPMs of various types.

A distinct objective of the project is to establish the technical feasibility and practical performances of prototype PSPMs, produced by adopting cost-effective construction methods, without compromising the excellence of the characteristics. This will be achieved by integrating the best features of the techniques developed by the different groups. Special components of the prototypes, such as fine-grid dynodes, will be designed and fabricated under the responsibility of western institutions and delivered to NIS partners for final assembly and processing.

Successful manufacturing of such prototypes by NIS industries will have an impact, not only on technical but on commercial aspects of PSPM applications as well. Scintillating-fibre tracking detectors will be built by the research groups from Annecy, Pisa, Strasbourg and Trieste, will be tested in association with the different types of PSPMs described above. These tests will be carried out partly in western laboratories and partly using particle beams provided by the accelerators existing at CERN. Applications of these detectors in the fields of high-energy physics, nuclear physics and medical diagnostics will be studied.
