Hi Tektron, zhak, all,

Sure wish there was a English translation ............

Somehow sent this twice.......arrrrrrrr.  Wont let me delete it, only modify..........

Some details of the reactor, I also prepared.
I am looking for a high-voltage transformer.
Skeleton Pyramid 8 * 1m also bought remained together.
20mm plastic pipe filled with acrylic.
Plastic Plugs 40mm had to be shortened, preventing the exact location of the coils.

Have an idea to make a removable panel.
What do you think such an option may damage the operation of TPP?

Hi Zhak,

I think that would work just fine!!!!!!!

Hi Tektron, zhak, all,

Sure wish there was a English translation of the total book.  Downloaded the PDF, working with translation software.
Thanks for the heads up!  Especially interested in the piezo discussion in the book. 

Unable to work on Pyramid today, family coming, things to do.....back on it tomorrow.

This wont make any sense without the equations and the background instruction leading up to this chapter. SORRY

§ 51 The piezoelectric effect 109
Consequently, the piezoelectric effect of quartz is described by the
equations
Pi - / 3llUl - / 3uU2 + / 3uli4,
Py =-Rii-gillie, E1.3)
Pz = 0.
As a result of polarization changes during deformation and
electric displacement D within the crystal. In this case, in general, deter-
determining the displacement of D1.2) under P is necessary to understand the amount of Fe + P ", where Fe
caused by an electric field, E, - deformation:
D = e0E + PB + P «. E1.4)
Here polarization of Pu is generally determined by the relations
E1.1). If the polarity of the electric field does not depend on the Fe-on
direction of E, we can introduce a scalar dielectric constant
e (§ 42) and write eoE + Fe = eeoE. Then
D =?? OE + PU. E1.5)
We now estimate the magnitude of piezoelectric effect on
sample of quartz. For this we consider plate cut perpendicular to the
perpendicular to the electrical axis X (si. Fig. 71), and assume that it subjected-
subjected to unilateral stretching along the axis.
Let the tensile stress is equal to si = 105 Pa. The resulting
strain is, and \ = si / C, where C - the elastic modulus (modulus of Yun-
Jung), depending on the direction of stretching and on the fixed side
edge of the plate or free (depending on boundary conditions for deformation
strain). We assume the side faces of the plate free. Then for
stretching along the X axis for quartz C = 7,8 • YU10 Pa. Then the deformation
is
Ad si YU5,, 1P-a
U October 13
Arising as a result of this deformation polarization, according to
the first equation E1.3), is
Px \ =? N "1 = 0,23 | 10 6 Kl/m2.
We now find the electric field caused by this
polarization. It can be determined from the expression for the electric displacement of
bias. In quartz, e depends weakly on the direction and we can use
by E1.5).
Since the volume charge density p inside the plate is zero,
then, according to the Poisson equation A4.1), divD = 0, and consequently, D =
= Const which means that the appearance of any section of the plate
X = const polarization P "will be accompanied by the appearance in the same
section of the electric field E in the opposite direction and a ve-
magnitude to the changes of both terms on the right side of E1 5)
compensate each other. Therefore found higher polarity
| Pxi = j3nui cause the electric field
Bxi = - ^ ui. E1.6)
? 0
Substituting for quartz e = 4.5 and using the above values
values ​​of /? and q «1, we find that \ E \ = 5900 V / m = 59 V / cm. When the thickness of the plate,
say, d = 0,5 cm voltage between the plates will be U = Ed, and 30 V.
