“…The spectra of electron beams are measured with magnetic spectrometers (Bugaev et al, 1974;Mangles et al, 2004;Li et al, 2006) and time-of-flight spectrometers (Gloeckler & Hsieh, 1979). The spectra of nano-and subnanosecond electron beams are also measured with the use of different methods (Bugaev et al, 1974;Afanasiev et al, 2005;Baksht et al, 2007), including the measurements of beam current attenuation in foils of different thickness (Baksht et al, 2010). Now, the most divergent spectral measurement data are those for supershort avalanche electron beams (SAEBs) produced in point-to-plane gaps in atmospheric pressure air.…”

In this paper, the spectra of electron beams produced in vacuum and gas diodes were analyzed to study the capabilities and limitations of their reconstruction from beam attenuation in foils of different thickness. The electron energy distributions were calculated using the Tikhonov regularization for Fredholm integral equations on minimum a priori assumptions. The spectra reconstructed in the study were those of electron beams, including a supershort avalanche electron beam, produced in experiments on a DUET plasma-cathode electron accelerator and SLEP-150M accelerator.

“…Cathodoluminescence (CL) was excited by a RADAN-EXPERT [13,14] accelerator with energies of particles in the range 100 -300 keV, a pulse duration of ∼20 ns [15], and the electron flux up to 10 12 particles per pulse. For kinetic measurements, CL was collected by a quartz optical fiber and directed into the entrance slit of a Solar TII MS2005 monochromator with the diffraction grating (1200 gr/mm).…”

We study the luminescence decay times of Ce 3+ : Lu 2 SiO 5 scintillator, co-doped with Sc 3+ and Li + ions, under the direct photoexcitation of Ce 3+ ions at 337 nm and excitation by a pulsed electron beam with energies of 100 -300 keV. The cathodoluminescence (CL) and photoluminescence (PL) decay times of studied sample are equal within the experimental error. Two emission bands are found: in the range of 370 -480 nm ("high-energy band") and 500 -570 nm ("low-energy band"). The highenergy emission band has the decay times ∼40 ns. The low-energy emission band has the maximum decay time ∼60 ns at 545 nm. The observed results show that the transport stage of Li:Sc:Ce:Lu 2 SiO 5 scintillation mechanism is not affected by a high negative space charge and high density of electronic excitations provided by the high-power electron beam.

Представлены результаты изучения деградации термолюминесцентных материалов Li 2 B 4 O7 : Be + Mn и Li 2 B 4 O7 : Zn + Mn под воздействием радиации (импульсный электронный пучок) и лазерного излучения. Обнаружено, что в результате воздействия высоких доз радиации структура изучаемых образцов частично приобретает аморфный характер, при этом в оптических свойствах эффект радиационного воздействия проявляется в возникновении зеленой люминесценции, обусловленной центрами марганца в тетраэдрическом окружении. При последующем облучении лазером с длиной волны излучения 350 nm происходит дальнейший распад центров люминесценции вследствие фотохимического окисления марганца Mn 2+ → Mn 3+ . Показано, что материал Li 2 B 4 O7 : Be + Mn имеет меньшую радиационную стойкость, чем Li 2 B 4 O7 : Zn + Mn. Ключевые слова: тетраборат лития, термолюминесценция, радиационная аморфизация кристаллической структуры, лазерная деградация центров люминесценции
