| چکیده | ||
| TAC (Time to Amplitude Convertor) is one of the most important time measurement instruments which has great significance in many fields of science, especially radiation physics. A TAC unit has been designed based on the START-STOP analog method and NIM (Nuclear Instrument Modules) standards. After designing the circuit, it was simulated by PSPICE software and constructed by discrete and integrated components. Accuracy of performance, linearity and time resolution of the TAC were checked in laboratory condition and a neutron-gamma discrimination experiment was carried out using this TAC. Results of these experiments and the spectrum of neutron-gamma discrimination completely agree with those from other similar TACs, and are, to some extent, better. | ||
