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 (&#964;<sub>1</sub> = &#964;<sub>2</sub> = &#964;) of 5 &#956;s 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.}
