TEM The authors describe a linear electron accelerator with a travel-
ling wave of 3.5 Mev energy. A waveguide loaded with disks is used as accelerating
system. The necessary law of wave phase velocity variation is brought about by
variation of the diameter of the apertures in the-disks. The 280-cm long wave-
guide is divided into three seotions. -In the first section., the phase velocity
is varied from 0.5 to 0.'97 C; In the second and third section it is equal to 0.98
and 0.99 a respectively. The electron equilibrium phase increases during the
acceleration process; its initial value is equal to 450 and is chosen according
to the optimum capture condition. The computational value of the h.fpower at the

accelerator input is 900 kw; the accelerator field intensity amounts hereat to
16.5 kv/cm- The accelerator 'output power (about 600 kw) is absorved in a mteel
lQad witty-water cooling; approximately 300 kK are dissipated in the waveguide
walls. An additional axisymmetrical magnetic field with an intensity up to 400
Gs is developed by solenoids for focusing the electrons along the waveguide axis .
An electron gun with three electrodes serves as electron source; it operates
pulsing synchronously with the magnetron generator and provides for a beam of 5-
6 mm diameter at the accelerator Input. The output parameters of the accelerator
measured arei the current is about 20-30 ma in the pulse of 2,Useo duration, the
average current is about 20-30 ~L a; the beam diameter is 3-4 mm with the diver-
gence angle of 7. 10-4 - 3.10-3 radian; the energy beam half-width is about 8%.

ABSTRACT" Application of strong focusing In linear accelerators.
The strong focusing method was proposed by Courant,
Livingston, Snyder, and Blewett (see refs at end of
abstract) in .1952., while Zellmanov sug- ted in 1953
that-a.lens be,put at the origin of the focusing
system. This half lens and multiple periodicity
proposed by Ya. B. Faynberg, A. I. Akhiyezer, and
K. N. Stepanov lead to a substantial reduction of the
field gradient needed for focusing. A. A. Sharshanov
developed a method for setting up approximate solu-
tions of the equation for particle-oscillations in
the patraxial region of the accelerating system due
to the alternate focusing and defocusing fcrces of the

They constructed the-lens using transformer core
material of thickness 0.35 mm. Three windings of
PEV-2 w1re of,2 mm diameter were covered with a layer
of BF-2 glue, placed into the pole grooves., and baked.
Such a coil was 'able to withstand current impulses
of the order of 2 Ica. For the ~.5 kqv proton acceler-
ator the authorp needed HI = 1.42-10D Oe/cm. This
required per pole n1 = 1,,000 ampere turnso i.e., with
a three-turn coil they needed approximately 300 a per
pole or approximately 600 a per lens, and 12 ka for
all the 20 lenses. The Hall effect in bisurath served
for measurements of the field gradient. The system
performed in a manner completely analogous to the
electrostatic system. Professor K~ D.-Slinellnikov

TITLE.- Investigation of accelerating systems operating with H waves
PERIODICAL: Atomnaya energiya, v. 10, no- 5, 1961, 469-477
TEM A report on the most important results of the experimental investiga-
tions of accelerating systems operating with H waves given here was made
already at the conference of the Fiziko-tekhnicheskiy institut AN USSR
(Institute of Physics and Technology AS UkrSSR) in November 1959. The
investigations showed that In contrast to the earlier view accelerating
systems operating with H waves (specially with H III type oscillations)
have important advantages in comparison to those operating with E 010 type
oscillations. These consist above all in the simplicity of the H wave
cavity resonator and in the fact that the use of H maves reduces high
frequency output. Linear accelerators operating with H waves can be used
up to particle velocities a witbout alterations in their fundamental
structure, which is not possible by the use of E 010 waves. Since, power

modern linear resonance amplifier, the H wave accelerator is also cheaper.
The reduction of the h-f power is brought about above all by the repeated
traversing by the particles through one and the name accelerating potential.
In order to find the optimum values of the size, parameters, and construc-
tion the change of the operating frequency f and the equivalent shunt R,,.,.

method for determining the fields in'the throat area of the trap of a given radius
is also given. Application of the Lagrangian and Hamiltonian of the charged parti-
cle motion and the utilization of the cyclic azimuthal coordinate of W-Lsymmtitric
