The need for large active volume detectors for ionizing radiations and particles, with both large area and thickness, is becoming more and more compelling in a wide range of applications, spanning from X‐ray dosimetry to neutron spectroscopy. Recently, 8.0 × 8.0 mm 2 wide and 1.2 mm thick single‐crystal diamond plates have been put on the market, representing a first step to the fabrication of large area monolithic diamond detectors with optimized charge transport properties, obtainable up to now only with smaller samples. The more‐than‐double thickness, if compared to standard plates (typically 500 µm thick), demonstrated to be effective in improving the detector response to highly penetrating ionizing radiations, such as γ‐rays. Here we report on the first measurements performed on large active volume single‐crystal diamond plates, both in the dark and under irradiation with optical wavelengths (190–1100 nm), X‐rays, and radioactive γ‐emitting sources ( 57 Co and 22 Na).
