“…Diamond is also an excellent material for UV detection [237][238][239][240][241], x-ray detection [242][243][244] and particle detection, including neutron detection [245,246], alpha particle detection [247], proton detection [248] and single-ion detection [249][250][251]. The 5.5 eV band gap of diamond induces an extremely low dark current and specific absorption of k \ 225 nm wavelength light.…”

A comprehensive review is presented on the advances achieved in past years on fundamental and applied materials science of diamond films and engineering to integrate them into new generations of microelectromechanical system (MEMS) and nanoelectromechanical systems (NEMS). Specifically, the review focuses on describing the fundamental science performed to develop thin film synthesis processes and the characterization of chemical, mechanical, tribological and electronic properties of microcrystalline diamond, nanocrystalline diamond and ultrananocrystalline diamond films technologies, and the research and development focused on the integration of the diamond films with other film-based materials. The review includes both theoretical and experimental work focused on optimizing the films synthesis and the resulting properties to achieve the best possible MEMS/NEMS devices performance to produce new generation of MEMS/NEMS external environmental sensors and energy generation devices, human body implantable biosensors and energy generation devices, electron field emission devices and many more MEMS/NEMS devices, to produce transformational positive impact on the way and quality of life of people worldwide.

“…Here, the priority is for very fast detection, so the diamonds were irradiated with 2.15 × 10 16 cm −2 1 MeV (Si dose equivalent) neutrons to reduce the carrier lifetime (and hence response) to a few nanoseconds [105]. This would be expected to reduce the CCD by more than an order of magnitude.…”

Diamond's many extreme properties, such as its radiation and corrosion resistance, large bandgap, high electron and hole mobility, make it an attractive semiconductor for UV and particle detectors. This paper reviews the properties that are exploited by the latest generation of detectors, such as the radiation hardness and detection mechanisms, and those which are less well understood, such as grain boundaries and priming effects. The UV and particle detectors and dosimeters that have been reported in the last few years are described and briefly assessed.

The problem of ensuring the accuracy and traceability of the measurement results of the absorbed dose in carbon ion beams, as well as the measurement results of the amount, fluence, flux density and energy of particles in proton and heavy charged particles beams is considered. Until now, in practice, these values have been measured only by indirect methods. The lack of approved measuring instruments for the quantities under consideration and the metrological traceability of measurement results of these quantities to standards did not allow achieving consistency of measurement methods used in practice and confirming the reliability of the results obtained. To solve this problem, three measuring complexes have been developed and created, which are included in the State Primary Standard of units of absorbed dose and absorbed dose rate of photon, electron, proton radiation and in carbon ion beams, quantity, fluence, flux density and energy of particles in proton and heavy charged particles beams GET 38-2024. The measuring complex for reproducing the unit of absorbed dose in carbon ion beams consists of an adiabatic calorimeter, a thermostating system, a data collection and processing system and a vacuum pumping station. To reproduce the unit of energy of protons and heavy charged particles, a complex has been implemented, which includes a total absorption calorimeter, a data collection and processing system, a vacuum pumping station and a particle count determination system based on the use of a Faraday cup. To reproduce the units of fluence and particle flux density in proton and heavy charged particles beams, a measuring complex has been created containing a Faraday cup, a set of collimators and a low current meter. The schemes, the principles and the results of studies of the metrological characteristics of the developed measuring complexes are described. The results are relevant for the field of radiation therapy and radiation resistance tests of the electronic component base used in the space industry.
