Diamond radiation detectors have promising properties i.e. high-temperature operation, low leakage current and radiation hardness. The authors have developed CVD diamond detector using lift-off method. We have successfully obtained high performance detectors which have 100.1% of charge collection efficiency for holes and 99.8% for electrons, provided that = 13.1 eV. The detector also achieved approximate 0.3 of one of the best energy resolution. This study reports a Fano factor evaluation of diamond detectors for alpha particles.
