The accelerating voltage pulse generators of relativistic electron beams and high-power ion beam accelerators are
subdivided into two main types: Marx generators and Tesla transformer type generators. In presented paper the at-
tempt to create the methodology of the engineering substantiation of parameters and designing the Tesla transformer
type generator for pulsed power accelerators is undertaken.

1 INTRODUCTION
Forming of accelerating voltage pulses of high-cur-
rent accelerators of relativistic electrons or (by changing
polarity) high-power ion beams is made in some stages
[1]. The energy accumulation and high-voltage pulse
generation is carried out with the help of Marx genera-
tors, and power magnification and temporary compres-
sion of pulse is realized with the help of pulse-forming
lines.
For accelerators with not extreme high parameters of
beams representing interest for solution of a lot of scien-
tific and applied problems one applies successfully also
primary accumulators on the base of resonance Tesla
transformer-type generators [2].
The main advantages of the Tesla transformer gener-
ator as compared to the Marx generator consist in the
following.
1. Possibility to work with rather high pulse-recurrence
frequency.
2. Lower cost due to a small number of used high-volt-
age capacitors, diminution of weight and dimensions.
3. Magnification of reliability and resource (safe life)
because of the absence of large number of spark switch-
es.
4. Possibility to apply commercial standard switch-
boards in the primary contour of the Tesla transformer.
These arguments were taken into account when up-
grading the "TONUS" accelerator [3]. This accelerator
was started in operation 30 years ago with the Marx
generator as a primary energy accumulator.
2 THE METHODOLOGY OF DESIGNING
The methodology of the technical substantiation of
parameters and designing the Tesla transformer genera-
tor we have used to replace the Marx generator was the
following.
It is known [4], that the choice of parameters of the
transformer and coordination of these parameters with a
capacitance С1 of the primary contour, in which the pri-
mary accumulation of energy is carried out, and capaci-
tance of forming lines С2, Fig. 1, is determined by the
accelerator efficiency.
Fig. 1. Electrical schematic of the Tesla transformer.
In Fig. 1: C1 - primary energy storage capacitance;
C2 - capacitance of the pulse forming lines; R - resis-
tance of pulse forming line insulation; L1, L2 - induc-
tance and R1, R2 - resistances of primary and secondary
contours, w1, w2 - number of coils, of primary and sec-
ondary windings, respectively; M - mutual inductance
of two contours.
So, it is considered, that for a charge of lines it is
necessary to have a coupling coefficient between wind-
ings of the transformer accordingly to
К = M(L1L2)1/2 = 1; 0,6; 0,385.
Frequencies of free oscillations in primary and sec-
ondary contours of the transformer should be identical,
i.e.
f1 =
112
1
CLπ =
222
1
CLπ = f2.
The package of computer programs for calculation
and optimization of parameters of the transformer was
developed in view of active power losses in primary and
secondary contours.
Differential equations for voltages and currents of
contours were calculated numerically under the standard
programs, and the parameters of the transformer with
cylindrical or conic windings are determined under the
special program of magnetic field calculation.
The program is realized in the following sequence:
- input of basic data (С1, С2, K, Uc1max, Uc2max,
- i1max, time of C2 charging),
- determination of the transformer parameters (L1, L2,

M, number of coils w1, w2 and sizes of windings),
- calculation of voltages and currents in contours as a
function of time without active losses,
- determination of the cross-section of winding wires,
their active resistances, and also the resistance R,
taking into account a self-discharge of a capacity С2,
- calculation of voltage losses, currents, energy and
efficiency of its transfer.
The experimental results obtained by putting into
operation the accelerator "Tonus-NT" and results of cal-
culation under the given program differ no more, than
by 10%.
3 CONCLUSION
On the base of computer simulation analysis it is
possible to make the following conclusions:
- The most effective work of the transformer is real-
ized for К ≈ 0.7, when the capacity С2 is charged
on the second half-wave of voltage, efficiency
achieves 80%.
- Most effective is the transformer, at which the
coaxial conic and cylindrical winding are displaced
from each other on some span defined by parame-
ters.
- The accessible amplitude of a high voltage is more
sensitive to set-up of resonance frequencies of pri-
mary and secondary contour, rather than to mutual
inductance between contours.
