Problems solved by technology

[0002] The electric field has a powerful effect on the charge in the field and can do work on it. This is the basic point of view of the electrostatic field theory and the theoretical basis for the acceleration of elementary particles by electrostatic accelerators in modern technology. However, since the electric field involved in the theory is invisible and the charge is a microscopic object , making the theory abstract and difficult to understand and verify

Embodiment Construction

[0019] The structure of the electrostatic acceleration demonstrator is as follows: figure 1 As shown, it consists of three parts: an accelerating track 1, an object to be accelerated 2, and a DC high-voltage power supply 3. in

[0020] The acceleration orbit constitutes as figure 2 As shown, it consists of four parts including an insulating base 4, an insulating hemispherical spherical surface 5, an insulating electrode support 6 and high voltage electrodes 7 and 8. Wherein the effect of insulating base 4 is to prevent electrode leakage, adopt hard insulating material, thickness is not limited, solid, hollow all can, height gets final product more than 5cm. The bottom of the insulating hemispherical surface 5 is placed on the insulating base 4 to provide a place for placing the electrodes and a sports field for the "metal spherical shell". It is inconvenient to carry. What this device adopts is a plexiglass hemispherical surface with a diameter of 50cm. The insulated elec...

Abstract

The invention belongs to the teaching experiment equipment technology field and discloses a static acceleration demonstration instrument. The static acceleration demonstration instrument consists of an acceleration track, an object to be accelerated and a power supply. The acceleration track consists of an insulation pedestal, an insulation semispherical spherical surface, an insulation electrode support and a high voltage electrode. The object to be accelerated is a conductive macroscopic metal ball; the power supply adopts a DC high voltage power supply; in the experiment, the DC high voltage power supply enables all high voltage electrodes to be electrified; through the constant charging and discharging on the electrified ball on all electrodes, the electrified ball is accelerated while moving, which show the action on the electrified object by the electric field. The static acceleration demonstration instrument is small in volume, easy in carrying and operation, and good in stability, strong in interest and applicable to the demonstration in classroom and can perform macroscopy on the microprocess.

Description

technical field [0001] The invention belongs to the technical field of teaching experiment equipment, and in particular relates to an electrostatic acceleration demonstration instrument. Background technique [0002] The electric field has a powerful effect on the charge in the field and can do work on it. This is the basic point of view of the electrostatic field theory and the theoretical basis for the acceleration of elementary particles by electrostatic accelerators in modern technology. However, since the electric field involved in the theory is invisible and the charge is a microscopic object , making the theory abstract and difficult to understand and verify. [0003] The instrument designed by the present invention uses visible electrodes to define the distribution area and direction of the electric field, replaces microscopic charged particles with table tennis balls sprayed with conductive paint, demonstrates the kinetic energy of table tennis balls with the height...
