LABORATORY OF NUCLEAR PHYSICS

CAT NO: DIDACTICNPS0023

Description & Specification:

LABORATORY OF NUCLEAR PHYSICS.
LABORATORY OF NUCLEAR PHYSICS This equipment allows students to carry out several experiments of nuclear physics. A computer data acquisition system is available via USB or serial port The software enables to gather data in real time
with automatic transfer to a file.
The complete PC control of all the data and of data acquisition
rate, as well as of Geiger-Muller counter enables to realize
one’s own experiments.
The functions of spreadsheet enable to analyze data, setup, to
plot diagrams and to print a copy of the screen.

TRAINING PROGRAM
• Geiger threshold
• counting efficiency
• backscattering
• absorption
• statistics
• half-life
• inverse-square law
• nuclear physics

COMPONENTS
• radiation counter
• detector
• set of calibrated absorbers (20 pieces)
• set of 5 sources
• USB cables

GEIGER-MULLER COUNTER
• scaler / timer preselection
• wide display of 6 LED digits
• audio output
• digital rateometer with alarm
• microprocessor controller included in the instrument
• on-line computer interface
• computer control and acquisition
• Geiger-Muller tube and inputs of sparking detector
• serial and USB ports

TECHNICAL CHARACTERISTICS
• Inputs: BNC connector for GM, MHV for sparking detection
• High voltage: 0-1200 V, adjustable in digital way by
increments of 10 V via hardware, or by increments of 5 V
with software included
• Display: LED 6-decades. It displays pulses, time,
programming time, CPM, CPS, alarm level and high voltage
• Audio : digital control of the volume of counting rhythm and
alarm point
• Modes: counting programming time, scheduled number of
runs, counts/min ; counts/second ; setting alarm level, setting
high voltage 0-1200 V, start/stop/reset, data transfer, as well
as the pause time between two subsequent detections
• Time/counting : programming time in seconds 1-9, 10-90, 100-
900, 1K-9K, 10K-90K, 100K-900K, programming detections,
CPM, CPS, programming alarm
• Data: serial port RS-232 for PC and MAC with USB port
• Power: input of 9.0 Vdc 500 mA
• included software: it displays (in real time) the simulated
analog rateometer with self-alignment, or a digital rateometer
in CPM or CPS, counting, time elapsed, programming time,
setting high voltage, acquisition time and number of
detections.

SET OF SOURCES
Set of 5 sources: Polonium-210, 0.1 μCi ; Césium-137, 5 μCi ; Sr-
900, 0.1 μCi ; TI-204, 1 μCi ; CO60, 1 μCi

GEIGER-MULLER TUBE
Complete detection system that uses a GM tube with diameter of
35 mm ; it is provided with a window for detecting Alpha, Beta,
Gamma radiations. The plastic support shows some grooves
for inserting proper supports for radioactive tablets for the
experimental study of inverse-square law.

ABSORPTION SET
Complete set of absorbers. It includes 20 calibrated absorbers of
5 mg/cm2 to 7200 mg/cm2 for being used in studies of attenuation
of α, ß and γ rays.
These absorbers are made of plastic material, of aluminium and
of lead.
