We describe a type of phase and frequency detector employing both an analog phase detector and a digital phase and frequency detector. The analog and digital detectors are mutually exclusive so that only one of them is active at any given time, resulting in a phase detector with both the broad capture range of digital circuits and the high speed and low noise of analog mixers. The detector has ...

due to high resolution power of sulfated cyclodextrins (hs-cds), utilization of these selectors for chiral resolution of 7 basic and 2 zwitterionic drugs have been examined. experiments were performed on a hp3dce instrument equipped with an on-column diode array uv absorbance detector. fused silica capillaries with an inner diameter of 50 ?m, an outer diameter of 365 ?m, and a total length of 4...

We examine the high count-rate performance of an energy-resolving detector in the three operating modes of the Advanced Photon Source (APS). Specifically, we present the optimal dead-time corrections for the SII Vortex silicon drift diode (SDD) detector using a digital pulse processor, highlighting the differences in operation between the 24-bunch, 324-bunch, and hybrid singlet modes of the APS...

A novel fluorescence detector based on collinear scheme using a brightness light-emitting diode emitting at 470nm as excitation source is described. The detector is assembled by all-solid-state optical-electronic components and coupled with capillary electrophoresis using on-column detection mode. Fluorescein isothiocyanate (FITC) and FITC-labeled amino acids and small molecule peptide as test ...

Monte Carlo simulation was used to calculate correction factors for output factor (OF), percentage depth-dose (PDD), and off-axis ratio (OAR) measurements with the CyberKnife M6 System. These include the first such data for the InCise MLC. Simulated detectors include diodes, air-filled microchambers, a synthetic microdiamond detector, and point scintillator. Individual perturbation factors were...

Abstract-A six-port receiver can restore the original modulated signal by calculating the detected envelopes and system parameters of the six-port circuit. The system parameters have been determined at each frequency in advance. The six-port receiver has an advantage in the point that the user can select the frequency arbitrarily, but there is a problem of nonlinear distortion in the detector b...

Measurements with a bare p-type high purity germanium diode (HPGe) submerged in a 19 kg liquid argon (LAr) scintillation detector at MPIK-Heidelberg are reported. The liquid argon–germanium system (LArGe) is operated as a 4π anti-Compton spectrometer to suppress backgrounds in the HPGe. This R&D is carried out in the framework of the Gerda experiment which searches for 0νββ decays with HPGe det...
