An alpha-spectrometer, consisting of a photodetector, a preamplifier, a pulse height analyser and a recording device for registration of the spectra is calibrated by means of an open alpha-emitter of known alpha energy (241Am). The energy spectrum of a radium source which is in equilibrium with its decay products, is recorded and evaluated. The alpha-energies found in this way are allocated to the corresponding nuclides of the radium decay series.

D321/15	1001005	Induction Tube Apparatus with 6 Coils

STUDY EFFORT CONSISTING OF MAGNETIC INDUCTION,TUBE WITH 6 INDUCTION COILS NET LOG 230V,NET LAB,SET OF 15 EXPERIMENT LEADS 75 CM,TRIPOD STAND 150 MM,STAINLESS STEEL ROD 12MM x1000MM,UNIVERSAL CLAMP,JAW CLAMP,ADAPTER PLUG-IN POWER

Guinea and feather tube apparatus with 6 induction coils connected in series. When a bar magnet (included in the scope of delivery) is dropped in the tube, a voltage is induced as it passes each of the respective coils. Due to the magnet's free-fall acceleration caused by gravity, the voltage peaks increase proportionally with the time (speed proportional to time), and the time intervals between the voltage peaks become ever shorter. The voltage characteristic can be plotted using any conventional storage oscilloscope or with a computer interface.

D321/16	1009932	THE POWER OF A MIRROR AND LENS,BASIC SET KRONCKE OPTICAL SYSTEM 230V ADAPTER PLUG-IN POWER

The Kröncke optical system provides robust reliability and offers all the precision needed for student exercises and practical courses in numerous experiments on ray and wave optics. The experiments are carried out in traditional fashion using the white light of a halogen lamp, the filament of which can be projected through an adjustable slit to observe interference in particular. All optical components are mounted in diaphragms with no stems and can easily be adjusted vertically and with precision into the optical light path when mounted on optical riders. Optical riders can freely move on the U-profile rail of an optical bench and can be attached with a minimum of force.

ACETATE CRYSTAL MODEL SET DIMENSIONS 12INx12INx12IN

Clarify Difficult-to-Explain Crystal Structures

Sturdy construction of this six-model set, a WARD’S exclusive, makes it a permanent classroom addition. Clear acetate reveals several aspects of each form, from pinacoids and prism faces externally, to simple pyramids internally. A brass mounting rod serves both as a crystallographic axis and a shaft for rotating each model on its labeled wooden base. A white cord serves as an axis, and black lines on the outer model illustrate yet another form. The set comes with a study guide. Size: 4–6".
