Подробно о продукте: Set of Bodies for Same Weight Demonstration Purpose

Application and feature
This apparatus is for observing the movement of elementary particles when studying the structure of a nucleus. It can be used in high schools or colleges.
It doesn't need chilling reagents or dynamic operation.
It can be used for steadily observing the moving features of high speed electrically charged particles such as a & β particles. It facilitates students to have direct impression of this knowledge.
This apparatus has 226 radium source, radioactive a particles, and a protective membrane on the surface. It is safe, reliable and no pollution at all.
production specification
diameter of the observation place: 130mm
DC high pressure electric field: 400V
Power source: 200V 50Hz
Power: approximately 150W
Size: 285*195*175mm
Radioactive 226 Ra, a radioactive source
Radioactive strength < 300Bq
Notes
due to ethanediol absorbing moisture in the observation place, it will be difficult to see the particles after some time, operation procedure I will be needed to solve this problem.
another reason for not being able to see the particles well might be the electrically heading fuse, check to see it is normal when necessary.
this apparatus uses electric fan for cooling, it can uses continuously.
High, medium and low buttons on the temperature adjustment device can be used to adjust the temperature of the cylinder so as to observe better.
normally ethanediol can be used continuously; but when the apparatus will not be in use for a long time, extract the ethanediol out of the observation chamber. At the same time, take out the radioactive source and put it in a special cylinder. Wash hands after operation with soap.
Power supply is three-core cables. The apparatus should be earthed.
Maintenance
if the electrically heading fuse is broken, it can be replaced with a ɸ 0.12mm Ni-Cr electrically heading fuse.
DC 400V, the positive polar is connected to a 2MΩ resistor and the base. Please be careful when repairing.
place the apparatus in a dry non-corrosive room when it is not in use for a long time.
