"Intensity-fluctuation low-coherence interferometry"
Source
Appl. Phys. B 71, 905-7 (Rapid Communications) (2000)
Abstract.
'Low-coherence interferometry' is an old technique which has had a wide development
 recently, and is based on the fact that interference with a path difference much longer that the
 coherence length gives rise to a 'channeled spectrum', which can be detected either by a dispersive
 spectroscope or by a second interferometer with a variable delay. We have tested an alternative way
 to detect path differences in this kind of interferometry, by analyzing the output intensity fluctuation
 correlations by a radiofrequency spectrum analyzer, and Fourier transforming the data. This method is
 suitable for very long path differences. The experiments have been performed with different lengths of
 single-mode fibre, in Mach-Zehnder and Fabry-Pérot configurations.

Title
X-ray interferometry of surfaces with Fresnel mirrors
Source
Applied Optics vol.39n. 10, April 2000, p.1633-36
Abstract
With a small double-mirror setup, we used grazing x-ray interferometry to study nanometric
steps. These one-dimensional steps were microfabricated on the surface of one of the two
mirrors; the other mirror provided the reference wave. Two geometries were studied. In
the longitudinal case in which the x-rays are parallel to the step edges, it is
straightforward to determine the step size. In the transverse case, one deals with
Fourier holography, and a reconstruction process for a phase object has been demonstrated
in the case of a single step.

Abstract
  In "white-light" (or "coherence domain") reflectometry (or, more generally,
interferometry), output light is usually analysed with a scanning interferometer. We
study the possibility of getting information from the radiofrequency spectrum of the
intensity fluctuations of the reflected light. The radiofrequency fluctuation spectrum
is obtained as the low-frequency part of the autocorrelation of the optical spectrum.
The distribution of reflections is then obtained by a Fourier transform. The result 
depends also on the chromatic dispersion, and then could be used for its measurement.

Abstract
  Gauss-Schell light sources are considered as models for synchrotron
  radiation. These sources can be viewed as random superpositions of coherent
  Gaussian beams. The relationships of the various widths that can be defined
  for the description of intensity and coherence, as related to the widths of
  the electron beam and the single-electron radiation (diffraction) pattern,
  are summarized. The description is also applied to the temporal coherence,
  which is of interest in the case of free-electron lasers. (15 References).

Abstract
  The spatial coherence properties of a monochromatic component of synchrotron
  radiation from an insertion device in the Fraunhofer limit are analyzed in
  the general case when the coherence distance is comparable with the beam
  width, expressing them by simple products and convolutions of Fourier
  transforms and autocorrelations on the single-electron field amplitude and
  the electron-beam position and angular distributions. In particular, the
  Gaussian approximation is discussed, in which case the far-field amplitude
  satisfies the Schell condition (its statistical properties can be described
  by a coherence factor depending only on the difference of the reciprocal
  space coordinates), and this discussion leads to simple estimates of the
  coherence widths. The coherence widths deviate from the Van Cittert-Zernike
  values when one or more of the phase space widths of the electron beam are
  close to (or smaller than) the diffraction limit. (20 References).

  Energy Balance in Coherent Electromagnetic Radiation
Source
  European Journal of Physics, vol. 15, 1994, pp. 29-32
Abstract
  Bunched charges, as in the "free electron laser", radiate more energy than unbunched
ones. For a better understanding of how the forces between particles determine the
conservation of energy, we take the simple model of two charges within a wavelength of
a sinusoidal wave, and show that the relative phase of the particle's motion with
respect to the wave is modified by the force between the two particles, and this
explains the extra work done by the wave. The phase shift is proportional to the
emitted field and depends on the retardation (particle distance divided by the speed
of light), and turns out to be independent of distance.

Abstract
  Thermally stimulated depolarization currents (TSDC) technique was used to
  monitor (in the range 100-620 K) the dielectric relaxations of (1) silica
  glasses of different origin and impurity contents (mainly Al and OH) and (2)
  soda-lime silicate (SLS) glasses, in which K/sup +/ and Ag/sup +/ were also
  substituted for Na/sup +/. In the SLS glasses three TSDC bands appear at
  temperatures lower than the main band of SiO/sub 2/ specimens: the position
  of two peaks depends on the nature of the monovalent ion. The polarization
  phenomena were larger in SLS than in SiO/sub 2/ glasses. The peak position
  and amplitudes were studied as a function of the polarization field,
  temperature and time. The origin of the relaxations is discussed. (10

Abstract
  As an optical source, an undulator can be described by its distribution of

  is a convolution of the single-particle diffraction pattern and electron beam
  distribution. Approximate peak brilliance and phase space widths are given.
  By analogy between brilliance and Wigner function, the depth-of-field and
  diffraction widths are shown to be essentially the same thing. The peak
  brilliance is shown to have a broad maximum as a function of the beam beta
  function ( beta approximately=L/2 pi ) but is practically independent of beta
  at short wavelengths. (13 References).

Abstract
  Coherent emission of light in the UV or VUV range can be obtained from an

  modulation is completely different from the one described by the usual
  Webster formula, and they find a simple analytical expression for a Gaussian
  input (large number of modes). Numerical calculations show that with 3 modes
  the result is already close to the Gaussian case, and that the frequency
  bandwidth increases as the square root of the harmonic number. (16

Abstract
  In large electron-positron colliding beam facilities the fields created by
  one beam in the crossing point are quite large and cause the particles in the
  other beam to radiate synchrotron radiation. The total power emitted in the
  form of this beam-beam synchrotron radiation is calculated for beams with a
  bi-Gaussian cross-section colliding head-on, and its dependence on beam
  separation is estimated. The radiation emitted in the forward direction is
  quite hard and has a complicated spectrum. However the radiation emitted at
  angles much larger than both 1/ gamma and the deflecting angle, is softer and
  has the properties of 'short magnet' radiation. Its spectrum observed at a
  fixed angle is directly given by the Fourier transform of the longitudinal
  dependence of the deflection field. The polarization has a simple azimuthal
  dependence. This radiation can be used for beam diagnostics. (17 References).

Abstract
  For protons with energies up to 400 GeV classical theory shows that the

  light spectrum. However it was shown that the magnetic field discontinuity at
  the edges of the bending magnets shifts the spectrum to the visible region
  where the normal light detectors can be used. For the use of the SPS as a
  proton-antiproton collider at 270 GeV with p bunches having 10/sup 10/ to
  10/sup 11/ particles and p bunches having 10/sup 9/ to 10/sup 10/ particles,
  it was necessary to enhance the synchrotron light by an undulator and to
  develop a more sensitive and gated detector to get p and p single bunch
  profiles. (10 References).

Abstract
  Theoretical studies, followed by experiments, show that owing to the abrupt
  change of the magnetic field occurring at the magnet edges, synchrotron
  radiation is emitted in the visible light range by a high energy proton beam.
  The spatial photon density being proportional to that of the proton beam the
  analysis of the emitted 'image' by a dedicated camera gives an accurate
  representation of the beam profiles. Based on these properties a
  non-interceptive detector has been developed and installed at CERN SPS proton
  synchrotron in order to measure the profile of the circulating beam. The
  results show that for an energy higher than 250 GeV and a beam intensity of
  at least 0.7 mA (10/sup 11/ p) the results are satisfactory. The spatial
  resolution being 100 mu m many beam parameters can be evaluated with good
  accuracy. (6 References).

Abstract
  The concept of wigglers as insertions in storage rings dedicated to
  synchrotron radiation is now old, but only recently have multipole wigglers
  for SR sources actually been brought into use. This confirmed the flexibility
  of such sources, though experience of matching experimental rigs to them is
  still somewhat limited. The flexibility arising from the use of wigglers,
  plus the fact that the radiation flux no longer depends only on the beam
  current and energy but can be adjusted, at each source point, by choosing the
  number of wiggler poles and the wiggler field, means that the efficiency of a
  synchrotron radiation source can be increased. Whereas a conventional X-ray
  ring may allow extraction of 10% of its radiated power, an
  'All-wiggler-Machine' (AWM) with 40 wigglers may allow 50% of its radiated
  power to enter the beam lines. This concept has been developed for the
  European X-ray source and an example of an outline design is described. (7

Abstract
  When modulated electron beams interact with electromagnetic fields they emit
  a radiation with two components, one coherent, dependent on the modulation,
  the other incoherent. A method is here proposed for calculating both effects
  at the same time with particular reference to modulated electron beams in
  magnetic or periodic magnetic fields for the production of electromagnetic
  waves at the further end of the infra-red region. Deals with the general
  expression as a function of time, with changes in frequency or wavelength,
  with the power spectrum and with beams modulated sinusoidally. (6
