We have developed a large CdTe pixel detector with dimensions of 23.7 × 13.0 mm and a pixel size of 448 × 448 μm. The detector is based on recent technologies of an uniform CdTe single crystal, a two-dimensional ASIC, and stud bump-bonding to connect pixel electrodes on the CdTe surface to the ASIC. Good spectra are obtained from 1051 pixels out of total 1056 pixels. When we operate the detecto...

Peak purity analysis is an evaluation technique for detecting the presence of coeluting impurities in highperformance liquid chromatography (HPLC) data. Running a peak purity check prior to analytical quantitation helps to ensure accuracy. In the development of analytical methods, peak purity analysis can reveal the presence of contamination during standardization and, by doing so, can prevent ...

Positron emission tomography (PET) detectors with the ability to encode depth-of-interaction (DOI) information allow us to simultaneously improve the spatial resolution and sensitivity of PET scanners. In this study, we propose a DOI PET detector based on a stair-pattern reflector arrangement inserted between pixelated crystals and a single-ended scintillation light readout. The main advantage ...

A new precision peak detector/full-wave rectifier of input sinusoidal signals, based on usage of dual-output current conveyors, is presented in this paper. The circuit gives a DC output voltage that is the peak input voltage over a wide frequency range, with a very low ripple voltage and low harmonic distortion. The proposed circuits use an all-pass filter as a 90 ̊ phase shifter of the processe...

The demand for faster and more accurate three-dimensional digitisers is increasing dramatically in on-line production areas, while the more traditional application fields (i.e. inverse engineering or rapid prototyping) are increasingly incorporating noncontact scanners as their accuracy grows. Recently, the authors have published a short review on three dimensional laser scanners (Forest & Salv...

Static interferometers whose optical path difference is not constant over the field of interferences are well adapted to demodulate sensing interferometers in the coherence multiplexing method. In this configuration the correlation peak can be spatially recorded on a linear detector array. However, the determination of the position of the peak maximum amplitude is often difficult because of the...

The operation of DA NE, the 1.02 GeV c.m. e + e collider of the Frascati National Laboratory with the KLOE experimental detector was successfully concluded in March 2006. Since April 2004 it delivered a luminosity > 2 fb -1 on the peak of the resonance, > 0.25 fb -1 off peak and a high statistics scan of the resonance. The best peak luminosity obtained during this run was 1.5 10 32 cm -2 s -1 ,...
