    On the dose response of some CVD diamond thermoluminescent

    Some literature concerning the linearity of synthetic or CVD diamond detectors are available (1 –6).According to some authors (3,4), the range of the linearity is closely connected with the crystal type and its composition, because impurities, such as B or N 2, even at p.p.m. level, can considerably influence its TL properties.. We investigated the linearity of the dose response in some CVD
