Abstract
Abstract An innovative monolithic diamond based Δ E - E charged particle telescope was fabricated in a layered structure featuring an ultrathin Δ E stage coupled to an E stage, about 2 μ m and 500 μ m in thickness, respectively. The diamond telescope was characterized in coincidence mode using α -particles emitted by a 241Am source, whose energy can be reduced by traveling in air at different pressures. The experimental Δ E - E scatter plots were analyzed and compared with the results from the nuclear simulation program SRIM. A good agreement between the experimental and simulated data as well as a good detector performance were found in terms of energy resolution and charge collection efficiency. Our experimental results indicate that the developed Δ E - E diamond telescope prototype can be used to provide information about the type and the energy of particles in nuclear physics experiments. In addition, the micrometric size sensitive volume of the Δ E diamond detector of the proposed device is particularly promising for the microdosimetric characterization of hadron beams.
