An extended form of a cooperative project proposal is presented. The main goal of the proposal is the design and
construction of a storage ring X-ray generator based on Compton backscattering. The project’s primary objectives
and organisation, together with a draft plan for the required N-100 storage ring reconstruction effort, are outlined.

INTRODUCTION
Intense X-ray beams are widely used in basic and
applied research. The beams are generally produced
using bremsstrahlung, synchrotron radiation and
Compton backscattering (CBS). The advantage of CBS
is a possibility of generating hard X-rays by low energy
electron beams.
In 1963, Arutynian, Tumanian, Milburn [1]
suggested that the Compton backscattering of laser light
by an electron beam could be used for producing hard γ-
quanta. Some years later, a scheme based on multiple
passes of electrons circulating through an optical
resonator located in a storage ring’s interaction region
was proposed for increasing the intensity of the
backscattered photons.
Subsequently, Huang and Ruth proposed a laser-
electron storage ring (LESR) based on this principle [2].
In the LESR the transverse beam emittance is
significantly reduced and intense X-rays are produced.
The electron beam is injected into the storage ring, and
then an intense laser pulse is introduced in a high - Q-
factor optical resonator. The length of the resonator is
chosen in such way that at each turn electrons collide
with the laser pulse at the interaction point (IP). The
laser pulse in the LESR interacts with the electron beam
much like an undulator.
During the project we plan to design and construct
an X-ray generator based on the CBS idea.
PROJECT INFORMATION
The main objectives of our project are:
•development of the underlying physics and design of
an X-ray generator based on Compton backscattering of
intense laser light off a relativistic electron beam in a
storage ring;
•study of the problem of concurrent X-ray generation
and laser cooling of an electron beam circulating in a
storage ring;
•development of the necessary X-ray optical and
diagnostic systems;
•reconstruction of the N-100 storage ring [3];
•commissioning of the upgraded N-100 storage ring.
We have already developed a preliminary focusing
lattice design and performed initial simulations of
electron beam dynamics in the storage ring.
The layout of the lattice is shown schematically in
Fig. 1. The arc lattice and phase advances of the
betatron oscillations were chosen to provide optimal
conditions for the correction of the natural chromaticity
of the ring. The matching of arcs and long straight
sections is accomplished by quadrupole lens triplets.
The existing bending magnets of the N-100 ring, with
bending angles of ϕ = 90°, will be used in the proposed
lattice [4].
The main parameters of the storage ring for the
stored beam energy E = 100 MeV are given in Table.
Fig. 1. Layout of the storage ring
The straight interaction section of the storage ring
and the axis of the optical resonator are coaxially
aligned. The resonator is formed by two high-quality
mirrors with reflection coefficients close to unity. The
round-trip spacing between the resonator mirrors is

equal to the electron orbit length inside the storage ring.
The single-mode laser generates light pulses of 100 ps
duration (pulse length σf = 30 mm), with a pulse-
repetition frequency f ~ 104 and an average power P =
100 W (flash energy being about 10 mJ). The laser
active element is manufactured from an yttrium-
aluminium garnet crystal activated with neodymium
(Nd: YAG). The wavelength of the main harmonic is λ =
1.06 µm. The photon beam is focused so that its
minimum transverse size is attained in the middle of the
interaction region.
Main parameters of the storage ring
Parameter Value
Operating energy range [MeV] 40-250
Injection energy [MeV] 70
Circumference [m] 13.7164
Beam current (per bunch), A 0.01
Tunes:
horizontal, Qx 3.427
vertical, Qz 3.149
Amplitude functions at IP [cm]:
horizontal, βx 3
vertical, βz 2.5
RF voltage amplitude [MV] 0.4
RF frequency [MHz] 699.28
Harmonic number h 32
Momentum compaction factor, α .099
Synchrotron oscillation tune, Qs 0.041
Energy acceptance, [%] ±3
Emittance εx , [nm] 14.7
Horizontal beam size at IP with IBS, [µm] 120
Natural chromaticity:
in horizontal plane, ξx -6.658
in vertical plane, ξz -13.856
Photon flux, s-1 2⋅1014
The laser-electron interaction gives rise to beam
energy spread. For the proposed lattice the operation
mode of the storage ring can be easily varied to control
the value of the momentum compaction factor. This is
obtained by a change of the dispersion function in the
injection straight section. This allows an increase in the
energy acceptance of the storage ring up to ±15 %.
Organisation, Management and Budget of the Project
Our project period is three years. A detailed Project
Plan will be prepared later. The X-ray generator will be
constructed at NSC KIPT using existing buildings and
infrastructure. Preliminary works have already started.
The project organisation is shown in Fig. 2. The role
of each of the participating groups is:
Ukrainian group – design, development and construction
of the storage ring. Investigation of electron beam
dynamics in the storage ring and software
development;
Russian group – theoretical study of the laser cooling
process;
Belarus group - design, development and construction of
laser and optical equipment;
USA group – theoretical and computational study of
laser-electron interaction and investigation of
femtosecond X-ray pulse production;
Netherlands group – theoretical and numerical studies of
the laser electron interaction.

The total budget support required from NATO is 12
Million Belgian Francs (MBEF), of which 2 MBEF will
be awarded to the NATO country participants. Fig. 3
shows how these funds are allocated among the project
partners. These funds will be provided to the Partner
country participants to cover the cost of scientific
equipment, computers, software, travel, and project-
specific consumables. Salaries will be covered from
other sources (state, academic, STCU…)

We expect the professional skill and experience of
the participating staff will allow us to carry out the
project on time and at a productive scientific and
technological level. We anticipate that the successful
realisation of our project goals will contribute to the
resolution of significant problems dealing with long-
term industrial and environmental issues with
multilateral ramifications. It should also promote
collaboration among scientists, industry and other end-
users and improve the integration of scientists from
Belarus, Russia and Ukraine into the international R&D
community.
