Sensitive detection of low doses of beta particles using quartz crystal oscillators

A method of determining beta radiation intensity based on calculated resonance frequency and calculated quality factor can include providing an electrical sensor comprising at least one prong, irradiating the first composite material of the one of the plurality of planar surfaces and the material of the second section with beta radiation from a beta radiation source; measuring at least one impedance value from the electrical sensor with an impedance analyzer; calculating at least one resonance frequency value based on the measured at least one impedance value; calculating at least one quality factor value based on the calculated at least one resonance frequency value; and determining the beta radiation intensity based on the calculated at least one resonance frequency value and the calculated at least one quality factor value.

Thermally coupled imager for performing time and position sensitive imaging of single photons

A thermally coupled imager includes a single photon detection pixel electrically isolated but in thermal communication with a thermal readout bus via a thermally conductive galvanic isolator, wherein the single photon detection pixel receives a single photon and produces thermal energy that is communicated to the thermal readout bus. A position and time of arrival of the single photon received by the single photon detection pixel is determined from voltage pulses produced by the thermal readout bus in response to receiving the thermal energy from the single photon detection pixel.
