Background

A Cyclotron (Cyclotron) is a device that makes charged particles perform a Cyclotron motion using a magnetic field and repeatedly accelerates the charged particles in the motion by a high-frequency electric field, and is an important instrument in high-energy physics. The main functions of the cyclotron are:

(1) action of magnetic field

When charged particles vertically enter a uniform magnetic field at a certain speed, the charged particles only do uniform circular motion under the action of Lorentz force, wherein the period is irrelevant to the speed and the radius, so that the charged particles can move for equal time (half period) after entering a D-shaped box every time and enter the electric field in parallel with the direction of the electric field to accelerate.

(2) Action of electric field

The narrow slit area between the two D-boxes of the cyclotron has a uniform electric field which changes periodically and is perpendicular to the diameter of the two D-boxes, and the acceleration is completed in the area.

(3) Alternating voltage

In order to ensure that the charged particles are accelerated each time they pass through the slit, and their energy is increased continuously, an alternating voltage is applied to the slit in accordance with the period of the particle motion.

The drawbacks of this structure of the cyclotron are: an electric field is formed between the two D-shaped boxes, when the direction-changing charging is not changed, the D-shaped boxes are continuous fields, the closed path of the detected charges in the continuous fields moves back to the initial position, namely the position of the initial point vertical to the electric field lines, the work is zero, namely the rotation is zero, the two semicircular D-shaped boxes need to be continuously and repeatedly changed for charging, once the charging is stopped, the moving charges cannot be continuously and repeatedly accelerated, so that the purpose that the continuous synchronous direction-changing charging can be achieved is relatively more wasted in electric energy, and the saving effect cannot be achieved.

The novel energy-saving particle trap accelerator shown in fig. 1 and 2 comprises a D-shaped metal box 1, an accelerating electric field of two groups of capacitors between the magnetic field and the two D-shaped metal boxes 1, and a direct current power supply for charging the capacitors of the accelerating electric field, wherein the middle sections of openings on two opposite vertical surfaces in the diameter direction of the two D-shaped metals 1 are provided with integrally-formed metal sheets 2, the metal sheets 2 and the upper and lower surfaces of the D-shaped metal box 1 are connected into a whole, the two D-shaped metal boxes 1 are respectively two shielding cavities, A, B two groups of capacitors are arranged between the two shielding cavities, the capacitor in the group A consists of an upper sheet A1 capacitor sheet and a lower sheet A2 capacitor sheet which are provided with positive charges and an upper sheet B1 capacitor sheet and a lower sheet B2 capacitor sheet which are provided with negative charges, and the positive charges and negative charges of the capacitor in the group A are arranged with the positive charges and the negative charges of the capacitor in the group B, The negative charge arrangement is reversed, positive and negative as shown in FIG. 1;

if the horizontal spacing distance between the A1 capacitor plate of the group A capacitor and the A2 capacitor plate and the horizontal spacing distance between the B1 capacitor plate of the group B capacitor and the B2 capacitor plate are a, and the spacing distance between the group A capacitor, the group B capacitor and the D-shaped metal box 1 is B, then a is greater than B, so that the electric field directionality is ensured, preferably, 2B is greater than a, and the capacitors are charged instead of being charged between the B1 capacitor plate, the D-shaped metal box 1, the A2 capacitor plate and between the A1 capacitor plate and the D-shaped metal box 1, the B2 capacitor plate rushing between the capacitor plates and the shielding cavity. The thickness of the capacitor plate is M, then M > a, the width N of the capacitor plate is as small as possible, and the positive and negative charge arrangement of the capacitors in the group A is opposite to that of the capacitors in the group B when viewed from left to right. If the longitudinal spacing distance between the group A capacitor and the group B capacitor is L2 and the length of the metal sheet is L1, L1 is greater than L2; the purpose is to shield the electric field of the group A capacitor and the group B capacitor by discontinuous isolation in the metal box.

The first time the particles are accelerated, then the particles enter the D-shaped metal box 1, and the movement radius of the particles under the action of the magnetic field is R₀Then L1 < 2R0, the purpose of which is to ensure that the moving charge can be removed fromOne side of the metal sheet 2 enters from the opening of the D-shaped metal box 1, and the other side of the metal sheet 2 comes out.

The vertical spacing height between the upper piece and the lower piece of the A1 capacitor piece, the A2 capacitor piece, the B1 capacitor piece and the B2 capacitor piece is D, the inner diameter height of the opening side of the D-shaped metal box is c, and D is more than c, so that the directionality of an electric field is single together with a and B.

When the particle is accelerated, the motion path of the particle is in the vacuum cavity, the particle is in the capacitance electric field and the shielding cavity, the magnetic field exists in the shielding cavity, the magnetic flux density is not 0, and the electric field intensity is 0; so R is mv/Bq, and L₁＜2R₀，a＞b，2b>a，

I.e., ρ B/> ρ a/, E ═ ρ/, E is the electric field strength, B is the magnetic flux density, ρ is the charge density,

therefore, 2B > a is to ensure that the capacitor is charged, not between the B1 capacitor plate and the D-type metal box 1, the a2 capacitor plate, and between the a1 capacitor plate and the D-type metal box 2, the B2 capacitor plate.

According to the principle of saving energy, when particles pass through the areas between the two capacitor plates A1, A2, B1 and B2, and do not pass through the area between the longitudinal sides of A, B capacitors, in order to ensure the singularity of the electric field direction, as shown in FIG. 1, a central line 1 between the two positive A1 capacitor plates is vertically connected with a central line 2 between the two negative A2 capacitor plates, which is a central line 3, and the distance between the positive A1 capacitor plate and the negative A2 capacitor plate and then the D-shaped metal box 1 is a + B long.

d＞c，2a-x(a+b)/2a-x＝c/d，x≥0，

Preferably, the particles move on the straight line of the central line 3, when moving charges enter the D-shaped metal box, the electric field also acts on the inner wall of the D-shaped metal box, the charge rearrangement occurs, and the force action is strong, so when the moving charges deviate from the central line, the moving charges are stressed unequally and collide against the upper inner wall and the lower inner wall of the D-shaped metal box, and therefore, an insulating layer is preferably added on the inner wall of the metal box.

In order to ensure the electric field directivity, the capacitance electric field direction and the relation quantity thereof can be obtained by the following modes:

this formula is shown in detail in fig. 3, where Z represents the amount in the longitudinal direction and E represents the electric field strength.

The metal sheet in the middle section of the opening of the vertical surface of the diameter of the D-shaped metal box 1 enables A, B two groups of capacitor longitudinal middle electric fields to be shielded in the metal box, so that two sections of electric fields which are opposite in direction and discontinuous are formed, the introduced accelerated charges can be accelerated repeatedly and accelerated after being rotated, and positive work is done.
