This item is designed to demonstrate the stabilizing effect of neutrons on the atomic nucleus. The ""protons"" are made of disc magnets while the ""neutrons"" are made of browned iron discs. The ""protons"" will, because they are magnetized, repel one another when placed on flat surface or overhead projector. The stabilizing effect of the ""neutrons"" is illustrated by placing them between the ""protons"", thereby eliminating the repulsive force. The ""protons"" are supplied with red marking, the ""neutrons"" with blue. Supplied as single pieces.
The “neutron” can be ordered under product code MO150905.

Frederiksen Spark Detector
The Alpha particle Spark Detector from Frederiksen has been developed to enable visualization of alpha particles. The apparatus can be likened to a GM tube, but using atmospheric air instead of the diluted quenching gas in the tube.
When alpha particles ionize the air in the spark gap of the detector, bright sparks can be both seen and heard. The apparatus incorporates a transparent lid, which allows clear observation of the sparks.
The detector requires connection to safe high voltage (EHT) power supply with voltage range of 0-5 kV or 0-6 kV. The apparatus can be safely used directly on bench top or table and includes a removable threaded steel rod for mounting the unit on a radioactivity bench (RA95610) or squat retort base with thumbscrew (ST96274).
• Gives clearly visible and audible response to alpha radiation
• Demonstrates the ionization of air by alpha particles
• Detects alpha radiation from radioactive minerals or radioactive sources
• Allows study of range in air shielding by different materials

Geiger-Muller Counter
This GM counter is the most versatile and easily operated model yet. The counting time can be set to 1, 10, 60 or 100 seconds or set to manual start/stop. Counting may be set to run repeatedly and the last, complete result is displayed in the main display while new counts accumulate in the auxiliary display. The counter accepts both BNC and Jack type GM tubes. With the optional USB connection it can interface with computer and if pulse output for further hardware processing is required, that is also available. For demonstration purposes the authentic clicking Geiger-counter sound may be turned on if preferred. Other improvements over the previous model include lower overall system dead time and lower current consumption, with the unit now being powered by AA batteries. The counter may also be powered from the optional mains adapter.

Half Life Simulation
This pack of 500 x 10 mm plastic cubes is used to investigate and demonstrate half-life. Each cube has one black face, the other faces all being yellow. The cubes are thrown or scattered like dice and those which land with the black face uppermost represent radioactive nuclei which have decayed. The black upward facing cubes are then removed, the remaining cubes thrown again and the process repeated. The removed cubes represent radioactive decay and decay curve can be plotted from the results.

Electron Diffraction Tube
The electron diffraction tube is highly evacuated tube with an electron gun consisting of pure tungsten heater filament and cylindrical anode all contained in clear glass bulb. The electrons emitted by the heated cathode are constrained to narrow beam by an aperture and are then focussed by means of an electron-optical system. The resulting tight, monochromatic beam then passes through micro-mesh nickel grating situated at the aperture of the gun. Onto this grid, thin layer of polycrystalline graphitised carbon has been deposited by vaporisation. This layer affects the electrons in the beam much like diffraction grating. The result of this diffraction is seen in the form of an image comprising two concentric rings that become visible on the fluorescent screen. spot resulting from the un-deflected electron beam continues to be visible at the centre of the rings. Also requires an EHT power supply.
Specifications:
• Max. filament voltage: 6.3 V AC
• Max. anode voltage: 5 kV
• Anode current: approx. 0.1 mA at 4 kV

Fine Beam Tube (Neon-Filled) with Connector Base
The Fine Beam Tube is used for investigating the deflection of cathode rays in uniform magnetic field produced by pair of 300 mm Helmholtz coils. In addition, it can also be used for quantitative determination of the specific charge of an electron e/m.
Located inside glass bulb with neon residual gas atmosphere is an electron gun, which consists of an indirectly heated oxide cathode, Wehnelt cylinder and perforated anode. The gas atoms are ionised along the path of the electrons and narrow, well-defined, luminescent beam is produced. Incorporated measurement marks facilitate parallax-free determination of the diameter of the circular path of the beam deflected in the magnetic field. The Fine Beam Tube is mounted on base with coloured connectors. In order to protect the tube, protective circuit is built into the base, which shuts off any voltage in excess of the base's pre-set cut-off voltage. The protective circuit prevents excessive voltages from damaging the heater filament and ensures ""smooth"" switch-on response once the voltage is applied. Requires 0-300 DC power supply and 300 mm Helmholtz coils.
