A semi-empirical method for efficiency calibration of an HPGe detector against different sample densities.

Applied Radiation and Isotopes, 2023
In this work, a semi-empirical equation in terms of γ-energy, and sample density is derived, proposed, benchmarked, and applied for the peak efficiency calibration of an HPGe detector with respect to an axial source-to-detector configuration. The samples

Research on SiPIN Detection Efficiency Calibration

IEEE International Conference on Electronic Measurement & Instruments, 2023
In contrast to the traditional experimental approach to detector detection efficiency calibration, the use of a monoenergetic X-ray radiation device for efficiency calibration is the preferred alternative for X-ray detector calibration because of the ...

A gamma ray sourceless efficiency calibration method based on the Boolean operation of the ray deposition process.

Applied Radiation and Isotopes, 2022
The general sourceless efficiency calibration has two major methods, Monte Carlo simulation and numerical calculation. Monte Carlo simulation as an important method to address the efficiency calibration in complex measurement systems, despite it being ...

An Efficient Digitizer for Calibration of Instrument Transformers

2018 IEEE 9th International Workshop on Applied Measurements for Power Systems (AMPS), 2018
A new, low cost and efficient digitizer for the calibration of the instrument transformers (IT) is presented in this paper. The proposed digitizer provides digital output directly proportional to ratio and phase errors of the instrument transformer under test, without the need of a separate analog-to-digital converter and signal processor. The existing

An efficient calibration technique for pipeline ADC

2013 IEEE 56th International Midwest Symposium on Circuits and Systems (MWSCAS), 2013
Capacitor mismatch and finite op-amp gain are two main error sources for high-resolution pipelined ADCs. This paper presents a high-efficiency digital calibration technique for multi-bit/stage pipeline ADCs. Firstly, capacitor mismatch in multi-bit stage is calibrated in foreground due to its stability to environment.
