“…9 CdTe and its related compounds (e.g., CdZnTe, CdMnTe) can be used for radiation detection at different temperatures. At À60 C, energy resolutions (FWHM) of 310 eV and 600 eV at 5.9 keV and 59 keV, respectively, were reported using CdTe detector; 10 at À37 C, FWHM of 311 eV and 824 eV at 5.9 keV and 59 keV, respectively, were demonstrated for a CdZnTe detector. 11 These compounds can also operate at increased temperatures, albeit with degraded energy resolution: for example, 53 keV (FWHM) at 122 keV was observed for CdTe at 92 C, 12 whilst a 9.4 keV (FWHM) at 32 keV was reported for CdZnTe at 70 C. 13 CdTe and CdZnTe are attractive choices for producing large area radiation detectors, and for this reason, they have received considerable research attention; 14 spectroscopic CdZnTe and CdTe detector imaging arrays, for example, have been proven by Wilson et al…”

Results characterising the performance of thin (2 μm i-layer) Al0.52In0.48P p+-i-n+ mesa photodiodes for X-ray photon counting spectroscopy are reported at room temperature. Two 200 μm diameter and two 400 μm diameter Al0.52In0.48P p+-i-n+ mesa photodiodes were studied. Dark current results as a function of applied reverse bias are shown; dark current densities <3 nA/cm2 were observed at 30 V (150 kV/cm) for all the devices analysed. Capacitance measurements as a function of applied reverse bias are also reported. X-ray spectra were collected using 10 μs shaping time, with the device illuminated by an 55Fe radioisotope X-ray source. Experimental results showed that the best energy resolution (FWHM) achieved at 5.9 keV was 930 eV for the 200 μm Al0.52In0.48P diameter devices, when reverse biased at 15 V. System noise analysis was also carried out, and the different noise contributions were computed.

“…Table 3 shows the energy resolution for Si (p-i-n), CdTe (p-i-n) and CdZnTe detectors developed at Baltic Scientific Instruments. 4,7 Si p-i-n detectors have an energy resolution already close to that of Si(Li) detectors. However, they compare unfavorably with the latter in terms of registered energies (thickness) and in registration sensitivity (area).…”

We discuss recent results obtained in the development of Si(Li), Si p-i-n, CdTe p-i-n and CdZnTe x-ray detectors with Peltier coolers for fabrication of laboratory and portable XRF analyzers. The characteristics of Si(Li) Peltier-cooled detectors are close to those of detectors cooled with the liquid nitrogen and remain the most preferred type of detectors for the tasks of x-ray fluorescence analysis. Considerable success was obtained in the improvement of the characteristics of CdTe p-i-n detectors and CdZnTe detectors with a metal-semiconductor-metal structure, effective in the energy range up to 100 keV. The spectra of all detectors are presented.

Aim: The objective of the present study was to develop a novel energy bar which is nutritious and cost effective. Materials and Methods: The components used for the novel energy bar were banana, orange, peanuts, raisins, cocoa butter, stevia leaves and oats. Mineral contents of energy bar were analysed by XRF technique. Results: The mineral contents were present in comparable amount. Major elements viz. K 17.15%, P 4.57%, Mg 1.43%, Ca 0.93%, Na 0.66%, S 0.54%, Fe 0.15%, Zn 0.05% and Cu 0.02% were present in energy bar. Conclusion: Minerals are good for overall growth of body. The energy bar also contains no preservatives, binding agents and sugar free. So, the energy bar is major source of energy and minerals for all age group individuals.
