To measure soft X-ray energy spectra at room temperature using diamond, we connected a 300-μm-thick single-crystal CVD diamond radiation detector with excellent charge carrier transport properties to a micro–preamplifier fabricated using CMOS technology via Φ97 μm electrodes. We attempted to measure the photon energy spectrum from a few keV to 60 keV at room temperature by reducing the leakage current and the total input capacitance to the preamplifier. The energy resolution for 5.9 keV X-rays from 55Fe was ΔE = (484 ± 10) eV (FWHM).
