Abstract

An innovative monolithic diamond based ΔE-E charged particle telescope was fabricated in a layered structure featuring an ultrathin ΔE stage coupled to an E stage, about 2μm and 500μm 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 ΔE-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 ΔE-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 ΔE diamond detector of the proposed device is particularly promising for the microdosimetric characterization of hadron beams.
