Inductive Detector of "Axion (Spin) Field"
(project)
In the article "The Theory and Projects of Measuring of the
"Axion Field"" a design of the
magnetic detector "axion
field" (AF) is described. We show an improved version of this detector below.
The design consists (see Fig.1, 2)
from two leaden plates X1 and X2 with thickness 1 mm in form of
letter γ. There is slot in the basis for installation of the
magnetic detector M. The magnetic detector M also overlaps a gap
slot in a leaden ring O.
The plates X1 and
X2 are assembled in a package, which is shown on Fig.2. The plates are
isolated from each other by dielectric pellicle D. It
has thickness of ~0.5-1 mm.
Dielectric bobbins C
with the electrical coil are mounted on plates X1 and X2. The
coils use electrical current, so that inside coils a magnetic field Hc=50 ampere/meter is directed as shown by arrows in
a Fig.1. The toroidal coils T with the core
from one layer of an iron tape by thickness of 0.1 mm and width 8 put on these
coils. The toroidal coils use electrical current, so
that inside coils a magnetic field Ht=90
ampere/meter will be directed as shown by arrows in a Fig.1, 2 (if parameters
of the iron core change, optimum Ht will be
different also).

The
plate X1 is connected to voltage +90-110V.
The
plate O is connected to voltage 0V.
The
plate X2 is connected to voltage -90-110V.
E - the
cone from electret film with a positive volumetric charge. It is intended for
reduction of induced AF in the iron shield F (see Fig.3).

Principle of Functioning
AF has a direction shown
by an arrow A (see Fig.4, 5). AF will
penetrate in dielectric D and leaden plates X1, X2. Electrical
potential between plates separates components AF with different electrical
pseudo-charge. A component with a negative pseudo-charge is run along positive
plate X1, and a component with a positive pseudo-charge is run along
negative plate X2. Then the components of AF are separated by a magnetic field Hc of electrical coils C along different
branches of plates X (see Fig.4 and Fig.5). The toroidal
coils concentrate AF in branches of plates X1 and X2.
The separated components of AF run
from the ends of plates X and lock headily between themselves through the
magnetic detector M.
(Usually
the magnet moments of AF components are mutually compensated. In the described
AF detector after partitioning of AF components they are joined again such a
way that their magnet moments add. There is a magnetic field, which it is
possible to measure by sensing magnetic detectors.)
Then AF penetrates into
a leaden ring O. Thus, all the field is
concentrated in small volume of ring O. The magnetic detector M
is in slot of it.
Such the design of the
AF detector will be more sensitivity, because it effectively uses AF
penetrating in the AF detector.
The Induction AF
Detector
High-sensitivity matnetometers are expensive and bulky devices. It is
possible essentially reduce the size and cost of the device for measuring AF if
to use equipment of modern radio reception and amplifications of weak
electrical signals.
It is necessary to
modulate AF sort four and use the inductive electrical coil of special design
instead of the magnetic detector.
The Description of
a Design

The design elements
are similar to design of the magnetic AF detector sort X, but the double
electrical coil I (see Fig.6) is placed in a shape of number “8” by
copper wire (instead of magnetic detector). The coil is shown from the face end
in Fig.7.
To manage the location
of AF in the area of the coil I, the toroidal
coil T2 is set up under leaden ring O on distance of 5-10 mm (see
Fig.8).
Principle
of Functioning
If to connect voltage to
leading-out wire 1, 2 of coil I, the current in the coil
will cause occurrence of magnetic field H of opposite orientation in the
next cavities, as it is shown in Fig.7. This magnetic field will cause
redistribution of AF between the next cavities of the coil I.
The delay in
redistribution of AF can be used for resonant detecting of AF if to use the
coil I in circuit regenerative receiver. It is the first variant of
detecting.
The toroidal
coil T2 operates the location of AF in area of the coil I. This
coil also can be used for modulation of AF, which will cause occurrence of
voltage of induction in the coil I. Induced voltage on leading-out wire 1,
2 is possible to amplify and use synchronous detecting for increasing
electronic anticounter measures and sensitivity of
detector. It will be the second variant of detecting.
