Electrodynamics acceleration of electrical dipoles
This article considers the acceleration of electric dipoles consisting of
thin metal plates and dielectric (barium titanate). The dipoles are of a
cylindrical shape with a diameter of the cylinder two centimeters and length
one centimeter. Capacity of the parallel-plate capacitor is three hundred
picofarads and it is charged up to the voltage of two hundred eighty kilovolts.
Pre-acceleration of the electric dipoles till velocity one kilometer per second
is reached by the gas-dynamic method. The finite acceleration is produced in a
spiral waveguide, where the pulse is travelling with voltage amplitude seven
hundreds kilovolts and power one hundred twenty-five megawatts. This pulse
travels via the spiral waveguide and accelerates the injected electric dipoles
in the longitudinal direction till the finite velocity eight and a half
kilometers per second over length seven hundred and seventy meters.Comment: 13 pages, 1 figur
Electromagnetic acceleration of electrically charged bodies
Acceleration of electrically charged bodies is carried out by the electric
field running via the spiral structure of the electric pulse. The accelerated
particles have a cylindrical shape with a diameter of cylinder two millimeters,
a length of the conical part thirteen millimeters and the total length three
hundred millimeters. Pre-acceleration of the cylinder up to speed one kilometer
per second is performed by gas-dynamic. The pulse with the voltage amplitude
two megavolts and the power three hundreds megawatts goes into the spiral
waveguide synchronously with the rod injected onto it. The rod is accelerated
by the traveling pulse in the longitudinal direction up to the finite velocity
six kilometers per second for length three hundreds meters.Comment: 12 pages, 1 figur
Gas-dynamic acceleration of bodies till the hyper sonic velocity
The article considers an opportunity of gas-dynamic acceleration of body from
the initial zero velocity till the finite velocity: five kilometers per second.
When the gas flow rate of the body pre-acceleration reaches one kilometer per
second, the body is accelerated at the front of the explosion wave propagating
along the coils of the hexogen spiral. This wave accelerates the body and,
finally, it reaches the velocity of five kilometers per second. The accelerated
body has mass one-tenth of a kilogram and diameter eleven and three tenths of a
millimeter. Acceleration length is six meters. At the slope of the spiral to
the horizon equal to seventy degrees the flight range of the body is equal to
sixteen hundred kilometers and the maximum height of the flight is eleven
hundred kilometers
A multi beam proton accelerator
The article considers a proton accelerator containing seven independent beams
arranged on the accelerator radius. The current in each beam is one hundred
milliamps. The initial part of the accelerator consists of shielded spiral
waveguides assembled in the common screen. The frequency of the acceleration:
three hundred megahertz, high-frequency power twenty-five megawatts, the length
of the accelerator six meters. After reaching the proton energy of six
megaelektronvolts the protons using lenses with the azimuthal magnetic field
are collected in one beam. Further beam acceleration is performed in the array
of superconducting cavities tuned to the frequency one and three tenths
gigahertz. The acceleration rate is equal to twenty megavolt per meter, the
high-frequency power consumption fifteen megawatts per meter.Comment: 12 pages, 2 figure
About_the_electrodynamic_acceleration_of_cylinder-shaped_particles
A possibility of electrodynamic acceleration of particles from the initial
zero velocity to the final velocity ten kilometeres per second the acceleration
length five meters is considered. After the electrostatic preacceleration
particles are accelerated at the trailing edge of the voltage pulse six
megavolts, which runs along the spiral turns. Accelerated particles have the
diameter six microns, and length one centimeter. Because of a pointed cone at
the head the particles can move in the air almost without loss of velocity,
penetrating into aluminum and water as deep as ten centimeter and water one
meter respectively.Comment: 19 pages, 1 figur
Acceleration of magnetic dipoles by the sequence of current turns
Acceleration of magnetic dipoles is carried out by the running gradient of
the magnetic field formed while sequent switching on the current turns.
Magnetic dipoles, with a diameter of sixty millimeters and full length one
meter, are pre-accelerated by using the gas-dynamic method to speed one
kilometer per second, corresponding to the injection rate into the main
accelerator. To prevent the turning of the dipoles by one hundred eighty
degrees in the field of the accelerating pulse and focus them, the magnetic
dipoles are accelerated inside the titanium tube. The magnetic dipoles have
mass two kilograms and acquire the finite speed five kilometers per second on
the acceleration length three hundreds meters.Comment: 7 pages, 1 figur
On measuring the size of nuclei of comets
Possibilities of measuring the size of nuclei of comets hidden by dust clouds
are discussed. To this end, the dust cloud should be irradiated with a flow of
rods accelerated in a linear mass accelerator to the velocity six kilometers
per second. Each rod should be equipped with a transmitter with a power of one
microwatt, which is destroyed in a collision with a comet's nucleus, or
continues to work if the rod passes through the dust cloud without collision.
Radio signals are received by three independent ground stations. At a distance
of one thousand kilometers from the nucleus of the comet the power of the
received signals is ten to the minus seventeenth Watt power, the receiver noise
power is ten to the minus twentieth Watt power.Comment: 17 pages, 1 figur
About the Electrodynamic Acceleration of Macroscopic Particles
An electric charge is imparted to macroscopic particles, whereupon they are
pre-accelerated in an electrostatic field by the high voltage U = 220 kV. Then
the particles are accelerated by a traveling electromagnetic wave with the
initial phase velocity lying in the range v/c = 1e-3 - 1e-5. Focusing the
particles is provided by electrostatic doublets. At the acceleration length L =
20 m, the particles with Z/A = 2.3e-7 increase their velocity from v/c = 1e-5
to v/c = 1e-4.Comment: 17 pages, 11 figure
An Intensive Pulsed Neutron Source Based On An Electron Ring Accelerator
A neutron source is proposed. It is based on a proton accelerator with the
energy Ep = 1.2 GeV, current Ip = 0.7A, pulse duration T = 3 mcsec, repetition
rate F = 60 Hz, and accelerator length L = 30 m.
Protons are accelerated by the field of electron rings. The electron rings
are formed from a tube beam by way of modulation and creating rotating motion
by crossing the magnetic field cusp. The frequency of modulation f1 = 142.8
MHz. The bunch is accelerated at the frequency f3 = 2856 MHz. The high
frequency power required for making the field is P1 = 6 - 150 MW/section, the
power transferred to the accelerated beam is P2 = 75 - 100 MW/m.
The bigger radius of the rings (r0 = 2 cm) and radial dimensions of the ring
(ar = 0.125 cm) are provided by the external magnetic field B0 = 2.4 T. The
longitudinal dimensions (az < 0.22 cm) are maintained by the wave moving
synchronously with the bunches. The number of electrons in each ring Ne = 3e12,
the number of protons Np = 3e10.
Protons are accelerated at the constant energy gain rate 40 MeV/m. The
electron rings are accelerated in the waveguide with the field strength Ez =
1.08 MV/m. The intensity of the proton beam is 1e13 p/pulse. The average
intensity of the neutron flux on a lead target is Ian = 1e16 n/s, the pulsed
neutron flux is Ipn = 8e19 n/s.Comment: 17 pages, 11 figure
