Determining the voltage linearity of a large impulse voltage divider used in the testing of ultra-high-voltage (UHV) equipment is a challenging task. This leads to the question of whether the uncertainty requirements, specified in the present edition of IEC60060 [1, 2], can be met in the UHV range. This paper presents the results of voltage divider linearity tests at voltages up to 2400 kV. Mea...
Lead halide perovskite CsPbBr 3 is a wide-gap semiconductor material potentially very attractive for next generations of real-time monitors and particle detectors in high-energy physics. Here, we present the first characterization crystalline point dosimeters with submillimeter size, under 6 MV X-photon beams used clinical radiotherapy. Current response devices proved to be promising terms fast...
The linearity of thermoluminescence (TL) dose response curve, in low dose levels, is affected by background signals appearing at the tail of the glow curves. The effects of these signals also restrict the use of the high temperature glow peaks in many applications. In this study, a new reading out procedure was presented to reduce the background signals and increase the resolution of the high t...
UNLABELLED CT is widely used for anatomic referencing of PET and SPECT images of small animals but requires sufficiently high radiation doses capable of causing significant DNA damage. Therefore, we described the relationship between radiation dose, biologic damage, and image quality to determine whether CT can be used without significantly compromising radiotherapy and tumor development studie...
