Sentence examples for beam cleaning from inspiring English sources
So, the developed laser combines three types of beam cleaning effects: beam clean-up at Raman conversion21, low-order transverse mode selection by special FBGs at the intermediate stage23,24, and the influence of Rayleigh backscattering at the final (random) stage of cascaded Raman generation in the graded-index fiber.
The pressure calculation for the vacuum cell compares the beam cleaning efficiency during the early commissioning stage when the accumulated beam dose attained 1 A h and 100 A h.
The operating pressure was speedily reduced by beam cleaning as the operation time increased.
The result of the pressure calculation obtained with the Monte-Carlo method shows that a mean pressure rise per beam current at 1.9 × 10−10 Pa mA−1 after beam cleaning to a beam dose 100 A h is reasonable and within typical specifications of the synchrotron light source.
After about 90 A.h of beam cleaning dose the total beam lifetime at 100 mA is approaching 11 h at 1.5 GeV.
IBAD-Cu films exhibit a strong (1 1 1) fiber texture, which is caused by the ion beam induced effects of substrate cleaning, preferential damage and preferential sputtering.

After cleaning, Ni was evaporated by using an e-beam evaporator at 1Å/s.
To avoid the expected ion beam-induced modification of atomic composition in the investigated volume, the sample surfaces were analyzed without sputter cleaning.
