The physicists working at CERN, in particularly with the LHC high-luminosity upgrade plans, showed great interest in the diamond detector technology in recent years. The applications which have stimulated greater interest are the ones connected to the use of the detector close to particle beams, therefore in an environment with high radiation level (beam monitor, luminosity measurement,...

Three-dimensional (3D) diamond detectors fabricated on high quality single-crystal CVD (scCVD) material show remarkable properties as 100% charge collection efficiency at electric fields as low as 0.04 V/$\mu$m. However polycrystalline CVD diamond (pCVD) is much more easily available with lower cost and larger areas. Hence the implementation of the 3D detector concept with pCVD diamond...

3D diamond detectors are at present investigated as they offer a superior radiation hardness with respect to planar detectors, promising to be the radiation hardest detector ever. Conductive channels are fabricated in the material by means of induced pulsed laser graphitization. The best characteristics are obtained by employing pulse durations as short as tens of femtoseconds. However a...

It is well known that in some detectors the performances deteriorate with the operation time or increasing flux (e.g. CdTe and CdZnTe detectors). This phenomenon is often described by the general term "polarization". The exact mechanism is usually unclear, but it is generally agreed that the effects are caused by a buildup of a space charge in the device. Such space charge decreases the...

Silicon tracking detectors for forward physics experiments at the LHC will be located 210m away from the proton-proton interaction point, but only a few millimeters from the proton beam. The proximity to the beam is essential for the physics programs of these experiments (for example, AFP) as it directly increases the sensitivity of the experiment. Thus, there are two critical requirements for...
