TL characterisation of a CVD diamond wafer for ionising radiation dosimetry

This work reports some thermoluminescent features of 28 samples cut from a free-standing polycrystalline diamond wafer grown by microwave assisted plasma CVD. All these samples show the same thermoluminescence (TL) peak at 540 K, particularly suitable for ionising radiation dosimetry. The homogeneity of synthesis in terms of TL responses as well as some criteria usually required for dosimetry work are studied. (C) 2003 Elsevier Science B.V. All rights reserved.
