DESCRIPTION:Speakers: Andrei Oleinik (Belgorod State Unversity)\nPyroelect
 ric effect in some single crystals exposed to temperature variations under
  vacuum provides a simple route for producing and accelerating electron be
 ams. In particular\, lithium tantalate (LiTaO₃) crystals can generate el
 ectric field strong enough to accelerate electrons to energies exceeding 1
 00 keV. This principle forms the basis of pyroelectric accelerators—comp
 act systems that operate without conventional external high-voltage suppli
 es or hazardous materials and have potential applications in electron\, io
 n\, neutron\, and X-ray generation\, as well as for calibrations detectors
  in large facilities.\nWe report  our recent achievements in development o
 f pyroelectric accelerators. The quasi-continuous X-ray generation from a 
 LiTaO₃-based pyroelectric accelerator driven by periodic temperature var
 iations is demonstrated [1]. This way allows to overcome the unpredictable
  nature of conventional pyroelectric X-ray sources. Stable X-ray emission 
 (as electron quasimonoenergetic production) was achieved over repeated hea
 ting–cooling cycles\, highlighting the potential of this approach for co
 mpact and continuous radiation sources. Nowadays\, the way to control the 
 energy of generated electron flow in a pyroelectric accelerator is propose
 d and developed\n\nThe research was supported by a grant from the Russian 
 Science Foundation (Project No. 26-72-10002).\n\n[1]. Karataev\, P.\, Ali\
