This paper describes the possibility of using an Electrically Programmable Analog Device (EPAD) as a gamma radiation sensor. Zero-biased EPAD has lowest fading and highest sensitivity in 300 Gy dose range. Dynamic bias control gate during irradiation was presented for first time; this method achieved higher compared to static-biased EPADs better linear dependence. Due degradation transfer characteristics irradiation, function safe operation area been found that determines maximum voltage at...
The possibility of using commercial p-channel power vertical double-diffused metal-oxide-semiconductor field-effect transistors (VDMOSFETs) as X-ray sensors is investigated in this case study. In aspect, the dependence sensitivity on both gate voltage and mean energy for three beams examined. eight voltages from 0 to 21 V are applied, well fitted proposed equation. Regarding energy, first increases then decreases a consequence behavior mass energy-absorption coefficients largest RQR8 beam....
The effect of X-rays on the p-channel power vertical double diffused metal-oxide-semiconductor field-effect transistors (VDMOSFETs) was investigated. VDMOSFETs were irradiated without gate polarization using three different Xray beams. Due to polyenergetic nature X-rays, their is much more complex than gamma radiation transistors. influence threshold voltage shift <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$(\Delta V_{T})$</tex> and...
In this article, the design of a high precision, low-cost PID acquisition system and control are shown. The consists measurement unit connected to Raspberry Pi 4, where temperature data is stored plotted. Ziegler–Nichols tuning method used calculate tune system. based on dual-core microcontroller Pico RP2040 using standard closed-loop algorithm. systems run Python MicroPython. This article uses PTC heating element as an example.
In this paper we investigated the feasibility of using a commercial programmable floating-gate MOS transistor (EPAD) as radiation dosimeter. The results show that EPAD with zero bias have sensitivity 9.2 mV/Gy and low fading. EPADs higher initial threshold voltage very good linearity dose. After its annealing at 70 °C there is visible recovery transfer characteristics due to parasitic parallel resistive path occurs during irradiation. Apart from that, slightly recovered. programming time an...
A high-quality, low-cost ventilator, dubbed HEV, has been developed by the particle physics community working together with biomedical engineers and physicians around world. The HEV design is suitable for use both in out of hospital intensive care units, provides a variety modes capable supporting spontaneous breathing supplying oxygen-enriched air. An external air supply can be combined unit situations where compressed not readily available. supports remote training post market surveillance...
HEV is a low-cost, versatile, high-quality ventilator, which has been designed in response to the COVID-19 pandemic. The ventilator intended be used both and out of hospital intensive care units, for invasive non-invasive ventilation. hardware can complemented with an external turbine use regions where compressed air supplies are not reliably available. standard modes provided include PC-A/C(Pressure Assist Control),PC-A/C-PRVC(Pressure Regulated Volume Control), PC-PSV (Pressure Support...
