“…Besides, low injection energy of 15 keV made it possible to supply the electron gun and the klystron from the same high voltage (HV) power supply (high voltage of the multibeam klystron KU-399a [26] used in this linac is 15 kV).…”

Based on Skobeltsyn Institute of Nuclear Physics (SINP) Moscow State University (MSU) experience in developing continuous-wave (cw) normal conducting electron linacs, we propose a design for such accelerators with beam energy of up to 10 MeV and average beam power of up to several hundred kW. An example of such design is the 1 MeV industrial cw linac with maximum beam power of 25 kW achievable with 50 kW klystron, which was recently commissioned at SINP MSU.

“…В современных клистронах для формирования электронных сгущений используются многолучевые системы и сложные многорезонаторные группирователи, позволяющие реализовать высокие значения коэффициентов усиления и полезного действия [1][2][3]. Однако при их разработке приходится учитывать фундаментальные ограничения, связанные с нарастающим действием расталкивающих сил пространственного заряда при образовании более плотных электронных сгустков.…”

“…The dimensions of a rectangular cavity a, b, and d were chosen from the conditions that there be no generation of higher-order modes TE 02 and TE 11 (0.6λ rf < a < 0.95λ rf , b < 0.5λ rf , where λ rf = c/ƒ rf ) and the horizontal physical aperture of the accelerator has its maximum value A hor = b/2 -R 0 . A KU-399 klystron (Russia) with P rf.max = 25 kW can be used as a continuous rf power supply [5]. For P rf.max = 6.9 kW, the value used for the Q-factor, and the prescribed dimensions of the cavity, the electric field intensity E max should not exceed 20 kV/cm in order that thermal deformation not detune the cavity [3].…”

The use of a subminiature electron storage ring in the weak-current regime (I b = 0.02 mA) as a source of coherent mm-range synchrotron radiation and a laboratory facility for studying electron scattering in a bunch is studied. The weak-current regime considerably simplifies the construction of a magnetic system and decreases the likelihood of the development of bunch instabilities. To make a more accurate assessment of some basic parameters of a subminiature storage ring, a calculation of the effective accelerating voltage was performed taking account of the transit factor of the rf-system cavity.A particularity of the weak-current regime is the simplicity of its implementation. Before the application of the weak-current regime is discussed, the amplitude of the effective accelerating voltage is calculated taking account of the transit factor of the cavity and methods for calculating the beam lifetime are analyzed.Calculation of the Accelerating Voltage. In a subminiature storage ring [1,2], the orbit of the beam lies inside the cavity of the rf system, while in ordinary storage rings it passes through the rf cavity.The amplitude of the accelerating rf voltage U max and the energy acquired by an equilibrium particle over one revolution ΔE rev are related with one another by the well-known equation
