Abstract
Design, Development and Simulation of a Nuclear Counting System using ATMEL Microcontroller has been presented in this study. The Nuclear Counting System (NCS) consists of Nuclear Detector GM (ZP1324)/Scintillation NaI (Tl) followed by Nuclear Detector Signal Channel (NDSC) Preamplifier- Amplifier-Shaper-Discriminator. The charge-sensitive preamplifier decay time constant (τ) is 10 μs. The gain of amplifier used in this channel is 26. Shaping amplifier which is the combination of high pass and low pass filter with equal time constant (τ1 = τ2 = τ) of 5 μs to increase the signal-to-noise ratio. Single ended or integral discriminator function is to eliminate the system noise and pulse height discrimination. Atmel-AVR ATmega8L 8-bit Microcontroller is High-performance, Low-power with 8Kbytes In-System Programmable Flash as the Processor, LCD display (16 ch, 2-line), High Voltage Power Supply (HVPS) for detector bias voltage and Low Voltage Power Supply (LVPS). An assembly language counting program based on BASCOM AVR IDE has been developed to control the operation of the designed NCS. The system has been designed and verified in Proteus 7.7 simulation platform.
