CVD diamond material was used to build position-sensitive detectors for sin
gle-charged particles to be employed in high-intensity physics experiments.
To obtain position information, metal contacts shaped as strips or pixels
are applied to the detector surface for one- or two-dimensional coordinate
measurement. Strip detectors 2 x 4 cm(2) in size with a strip distance of 5
0 mum were tested. Pixel detectors of various pixel sizes were bump bonded
to electronics chips and investigated. A key issue for the use of these sen
sors in high intensity experiments is the radiation hardness. Several irrad
iation experiments were carried out with pions, protons and neutrons exceed
ing a fluence of 10(15) particles/cm(2). The paper presents an overview of
the results obtained with strip and pixel detectors in high-energy test bea
ms and summarises the irradiation studies. (C) 2001 Elsevier Science B.V. A
