Abstract

CVD diamond film has many excellent features, which promotes its potential application in radiation detection. In this paper, one kind of 1x128 array detector was developed by using a free-standing (100) textured CVD diamond film with a thickness of 300µm. The charge collection efficiencies (η) and distances (d) of the detector were investigated by using ²⁴¹Am α particles (5.5MeV), ⁶⁰Co γ-rays (1.25MeV), ⁵⁵Fe X-rays (5.9KeV), resulting that the CVD diamond detector boasts high η (>38%) and d (>115µm), among which the η and d of X-ray reaches 41.70% and 125µm, respectively.
