1. INTRODUCTION
In the first 80 years of accelerator development the
majority of constructed electron linear accelerators and
synchrotrons in the energy range of 100…2000 MeV has
exhausted the opportunities of their use in nuclear
physics because of the small pulse duration with respect
to the pulse repetition period. The second life for these
accelerators was promised by the use of beam stretchers.
About 15 projects of such installations have been
proposed. By 2002 only six projects were realized. At
present, two of the installations in operation have
stopped and have been disassembled; the nuclear
physics research is going on only at three installations
[1-3]. During the last ten years basically recirculators
have been used for experiments with electrons. These
were created using acceleration technology on the basis
of superconductivity, and also using warm accelerating
systems. The extraction of electrons from these facili-
ties, in comparison with stretchers, does not represent
essential difficulties: JLab, MAMI, S-DALINAC [4-6].
The last achievements in the high technology fabri-
cation of accelerating structures for TESLA [7] allow to
obtain an accelerating gradient near 35 MeV/m. Use of
this structure for operation in a continuous wave (CW)
mode allows to design a sufficiently compact accelera-
tor with an energy of about 400 MeV, with a continuous
beam and with the appropriate parameters for nuclear
physics research. The same mode of operations using an
injector with very short bunches allows to create either a
free electron laser with high brightness or a neutron
source with unique characteristics.
Already projects using accelerating structures of the
TESLA-type in CW mode for free electron lasers in the
x-ray range of wavelengths have appeared [8.9]. The
first turn of the 40 MeV superconducting linear acceler-
ator ELBE is realized [10]. It is intended for use in nu-
clear spectroscopy, radiation physics, neutron physics
and as the free electron laser in the infra-red area of the
spectrum.
The linear accelerators LU-2000 and LU-300, con-
structed at KIPT in the sixties of the last century, have
become outdated and do not answer the requirements of
modern physical experiments. A new particle accelera-
tor installation with 400 MeV electron energy is pro-
posed at NSC KIPT on the basis of available capital
structures, using the newest technological achievements
in the field of acceleration of electron beams. (If a man-
agement of the tendencies in development modern ac-
celerator base for reception of continuous electron
beams,??) On the basis of modern accelerator develop-
ments regarding continuous electron beams, this instal-
lation should be either a superconducting linear acceler-
ator working in CW mode, or a recirculator on the basis
of TESLA-type superconducting accelerating structures.
Estimations of costs and other characteristics of the
proposed accelerator are based on information about the
accelerators in the BESSY SASE-FEL [8] and TESLA
[11] projects, using the same structure.

2. 400 MeV SUPERCONDUCTING
ELECTRON LINAC
Most suitable for accommodation of the linear accel-
erator is the lens corridor and target hall at NSC KIPT
(see fig.1). This is because these areas adjoin the SP-
103 hall where the magnetic spectrometer is located,
and also building 46, which can be used for accommo-
dation of the control of theaccelerator complex, and for
equipment necessary for physics research on the beams
(for beam dynamics research or for research making use
of the electron beams?). The SP-103 hall can be used
both for accommodation of new spectrometers, and for
free electron lasers activities.
For obtaining 400 MeV energy using a quite achiev-
able gradient of 15…20 MeV/m about 20 standard ac-
celerating structures have to be used. For obtaining the
necessary final energy, two modules of the TESLA ac-
celerating structures are sufficient, as one module con-
sists of 12 units with a total length of 15.927 m [11]
(???).
Fig. 1. Experimental setup at LU-2000 output
The minimum rf-gun length with 25 MeV pre-accel-
erator would be about 4 m. In this way, the minimum
building length for housing the accelerator should be 36
m, so that with additional hardware it must be no shorter
than 40 m. For this reason, there are two options for
housing the accelerator: in the lens hall and in the target
hall with displacement of the accelerator axis relative to
the existing beam pathway. The latter is necessary in or-
der to place a part of the accelerator in the re-loading
tunnel, since the length of the target hall is smaller than
needed. The existing re-loading does not permit to place
a module of 16 m long in the bunker, however, if one
lengthens the existing hatchway by 12 m, this problem
should be solved. A study of the positioning of the pro-
posed TESLA accelerator in the tunnel indicates that the
transverse cross-section of the considered premises can
accommodate the accelerator.
The cost of one TESLA accelerating structure in the
accelerator together with the infrastructure required to
run this system (power, vacuum, cryogenic, high-fre-
quency, control, etc.), as follows from the assessment of
other references [8,11,12], by mass manufacture
amounts to 100-215 thousand euro.
From budget costs of the TESLA accelerator, based
on expenses for the construction of TTF, it follows, that
the capital expenses for purchase of the main accelerat-
ing modules and RF system of the TESLA accelerator
make 51% of all capital expenses, and the cost of annual
operation of the accelerator, i.e. expenses for the electric
power, regular klystron replacement or restoration, heli-
um loss under working condition of the accelerator of
5000 hours per one year make 7% of these expenses.
The capital expenses for the 400 MeV linear acceler-
ator will amount to more than 6 million euro, and annu-
al operational charges - 420 thousand euro. The beam
power of such an accelerator will be about 40 KW. The
power of cryogenic losses is more than 630 W at a tem-
perature of 2K. Yet, power expenses on the cryogenic
system will be dominant, and for this reason the total
power used by the accelerator will exceed 2.5 MW.
3. 400 MeV RECIRCULATOR WITH SUPER-
CONDUCTING ACCELERATING STRUC-
TURE
Accelerating structures costs of the linear accelerator
form the largest part of the common capital expenses of
the construction of the installation. Using a beam circu-
lation scheme allows to reduce length, and, hence, cost
of the accelerating system.
Let us consider a 400 MeV recirculator, using the mag-
netic equipment from the EUTERPE electron ring [13].
The recirculator is supposed to be placed in the LU-
2000 target hall and beam extraction is to be in SP-103
hall (see fig.2).
As the accelerating system is placed in the straight
sections of the recirculator, two TESLA structures are
supposed to be used in which the beam receives a
36 MeV gain of energy. The recirculator magnetic
structure is considered in ref. [14].
At a beam power of the accelerator of 40 kW, the
capacity of recirculator magnetic system will not exceed
170 kW. The capacity of the refrigerator should make
about 280 kW. Costruction cost of the recirculator mag-
netic system is estimated at 280 thousand euro.

4. CONCLUSIONS
The comparison of two variants of installation shows
essential recirculator advantages, lower capital expenses
for the construction of the accelerator, and smaller ex-
penses for operation.
Use the of the recirculation circuit version of the
beam allows consistently increasing the maximal energy
in the installation in the process of increasing volume of
means found for the realization of the project, creating
.
Fig.2. Recirculator layout in the LU-2000 target hall
on each stage an opportunity for realizing experiments
with the beam. So, with the presence of the 10 MeV in-
jector and the first distributing magnet, the beam can be
guided to the SP-103 hall and to the lens corridor. After
installation of the first accelerating module of 36 MeV
in the straight sections of the recirculator the opportuni-
ty of working with a beam up to 46 MeV in the SP-103
hall will appear. After installation of all four distributing
magnets it is possible to work with the beam with this
energy in the overload hall and lens corridor. The instal-
lation of the accelerating module in other straight sec-
tions will allow lifting the beam energy in these work-
stations up to 83 MeV. The installation of magnetic ele-
ments of the EUTERPE-ring will allow receiving 192
MeV energy in the SP-103 hall and 228 MeV in the
overload and lens halls. The complete installation of 5
arcs with 4 magnets in every arc will allow getting 410
MeV energy in SP-103 hall and a little bit lower energy
in other halls.
The injector replacement will allow effectively to
use the accelerator for nuclear physics, as free electron
laser and as a neutrons source.
