ESTIMATION OF BBU THRESHOLD CURRENT IN AN INHOMOGENEOUS ACCELERATING SECTION

In this work we describe the procedure of estimation of regenerative beam blowup threshold current in an inhomogeneous accelerating section. The self-consistent problem of transverse motion of particles in the field of dipole mode excited by the beam is solved. The distribution of dipole field near the structure axis and the energy variation of beam particles were calculated before simulating the transverse dynamics. The threshold current for S-band industrial linac designed for radiation sterilization of medical products is estimated.

Research on High Voltage Power for 10kV Linked SVG

10kV linked SVG module power supply from their own h-bridge power, supply is unstable. To solve this problem, this paper proposes a new way to take power, using a combination of full-bridge push-pull circuit with isolation transformer to solve the logical drive power between the power module and the SVG device self-consistent problem. The paper detailed analysis of the working principle and characteristics of this new way to take power, and verified on prototype, present the experimental results.

Semantic Voids, New Testament Translation, and Anachronism

This essay addresses the problem of theologically-inflected English translation choices of the New Testament, and how those translations come to bear in theologically disinterested scholarship on Christian beginnings. As a case study I examine the ubiquitous rendering ofekklesiaas “church” in Paul’s letters. I argue that Paul was not referring to Christian churches, but to the “day of theekklesia” in the Septuagint, when God’s people gathered at Sinai/Horeb. Paul is not making Christians out of pagans; he is making quasi-Judeans out of gentiles. Renderingekklesiaas “church” inscribes Christian essentialism into Paul’s letters, and masks what Paul is actually doing with this word. The bridging of Greek-to-English semantic voids on the part of translators and New Testament scholars is a consistent problem that frustrates advancements in Pauline studies, and in studies of the religions of the Roman Empire more generally.
