A detector setup has been built and tested with particles in a wide range of Lorentz factors (from about 10 3 to about 4×10 4 crossing different types of radiators. The measured double-differential (in energy and angle) spectra of the TR photons are in a reasonably good agreement with TR simulation predictions.

- ПубликацияТолько метаданныеOn the Polarizability of a Cluster of Interacting Particles in Polarization Radiation(2020) Sergeeva, D. Y.; Tishchenko, A. A.; Сергеева, Дарья Юрьевна; Тищенко, Алексей Александрович© 2020, Pleiades Publishing, Ltd.Abstract: The study considers diffraction radiation, which is excited when an electron moves near a cluster of two interacting subwavelength particles. The interaction is manifested in the fact that the radiation field from each particle is determined not only by the external field of the electron, but also by the field of the neighboring particle. Based on the obtained expressions for the radiation field, the function of cluster polarizability is determined. It characterizes the cluster response to the field of the electron as a whole. It is interesting that the obtained response function of the cluster to an external field, even in the framework of linear theory, generally depends on the external field itself.

In order to solve this problem, corrections to the existing x-ray TR module in Geant4 are proposed. With these corrections, the results of the simulations are in a good agreement with the angular TR distributions predicted by theory and obtained in the test beam measurements using a 480 um Si pixel detector and Mylar radiator.

- ПубликацияОткрытый доступTHZ RADIATION BY FREE ELECTRONS FROM 2D PHOTONIC CRYSTALS AND METASURFACES(НИЯУ МИФИ, 2023) Tishchenko, A. A.; Sergeeva, D. Yu.; Garaev, D. I.; Гараев, Дамир Ильдарович; Сергеева, Дарья Юрьевна; Тищенко, Алексей АлександровичTerahertz radiation sources based on the radiation of electrons in external fi elds attracts the attention of researches due to the huge energy stored in relativistic electron beams. Even a little part of this energy, being radiated, makes it possible to produce powerful radiation in various parts of spectrum, including terahertz one, which is exploited in gyrotrons, magnetrons, orotrons etc. Besides its customary applications in powerful radiation sources and in non-destructive diagnostics of relativistic electron beams, the last decade SPR is intensively investigated for more exotic structures, like plasmonic crystals [1-3], graphene nanoscale gratings [4, 5], metasurfaces [6, 7]. These novel structures are widely investigated today due to their tunability, opportunity to tailor the properties of the surfaces, which results in developing novel modulators [8] and fi lters [9] — the key elements in applications of modern optics.
- ПубликацияОткрытый доступRADIATION FROM A METASURFACE AS AN INSTRUMENT FOR ELECTRON BUNCH DIAGNOSTICS(НИЯУ МИФИ, 2023) Tishchenko, A. A.; Sergeeva, D. Yu.; Тищенко, Алексей Александрович; Сергеева, Дарья ЮрьевнаRadiation from electron bunches is usually used for diagnostics of its transverse sizes in accelerators and colliders including FELs and synchrotron injectors [1,2]. However, the methods of diagnostics continue to improve. There are some ideas on single-short diagnostics, or non-destructive diagnostics, or using new types of targets, among which metamaterials and photonic crystals seem to be attractive. In this report we suggest using incoherent transition radiation from two-periodical targets in order to defi ne transversal sizes of the bunch. Usually the diagnostics is reduced to comparison the measured data to the theoretical one, which take in account the coherent eff ects [3,4]. The generally accepted approach to take into account coherence from electron bunches consists in multiplying the radiation intensity from one particle by the bunch form-factor, which takes into account its size, shape, and distribution of electrons. We show that in polarization radiation for a wide class of structures, such as photonic crystals and metasurfaces, this approach is incorrect [5,6].
- ПубликацияОткрытый доступTransition radiation measurements with a Si and a GaAs pixel sensor on a Timepix3 chip(2020) Dachs, F.; Alozy, J.; Bergmann, B.

At present there are no detectors capable of identifying charged particles with reliable efficiency in this range of γ. New developments in high granular pixel detectors allow one to perform simultaneous measurements of the energies and the emission angles of generated transition radiation (TR) X-rays and use the maximum available information to identify particles. First results of studies of TR energy-angular distributions using gallium arsenide (GaAs) sensors bonded to Timepix3 chips are presented. The results are compared with those obtained using a silicon (Si) sensor of the same thickness of 500 μm. The analysis techniques used for these experiments are discussed.
- ПубликацияТолько метаданныеDiffraction radiation from a charge as radiation from a superluminal source in a vacuum(2020) Potylitsyn, A. P.; Sergeeva, D. Y.; Strikhanov, M. N.; Tishchenko, A. A.; Потылицын, Александр Петрович; Сергеева, Дарья Юрьевна; Стриханов, Михаил Николаевич; Тищенко, Алексей АлександровичAn analysis of spectral-angular characteristics of diffraction radiation, both incoherent and coherent, has been performed. It is shown that radiation processes can be interpreted as Cherenkov radiation, which is produced by a region of dynamic polarization moving along a target edge with super-luminal velocity v(SL). Such radiation is generated if the condition v(SL) > c is fulfilled, which is the conventional 'threshold' Cherenkov condition.

A.; Sergeeva, D. Y.; Shulga, E.; Smirnov, S.; Smirnov, Y.; Strikhanov, M.; Teterin, P.; Tishchenko, A.

In most of the detectors, emission of the X-ray transition radiation (TR) starts at Lorentz factors above γ∼500 and reaches saturation at γ∼2÷3⋅103. However, many experiments require particle identification up to γ∼105, which is very difficult to achieve with conventional detectors. Semiconductor pixel detectors offer a unique opportunity for precise simultaneous measurements of spectral and angular parameters of TR photons. Test beam studies of the energy and the angular distributions of TR photons emitted by electrons and muons of different momenta crossing several types of radiators were performed at the CERN SPS with a 480 μm thick silicon detector bonded to a Timepix3 chip. High resolution images of the energy−angle phase space of the TR produced by different radiators were obtained and compared with MC simulations. The characteristic interference patterns are in agreement with the theoretical models with an unprecedented level of details. The studies presented in this paper also show that simultaneous measurements of both the energy and the emission angles of the TR X-rays could be used to enhance the particle identification performances of TRDs.
