The high intensity polarized electron source is a critical component for future nuclear physics facilities. electron-ion collider requires gun with higher voltage and bunch charge compared to any existing source. At Brookhaven National Laboratory, we have built an inverted direct current (HVDC) photoemission large cathode size. We report on the performance of GaAs photocathodes in gradient up 1...

A novel ultra-high compliance, low power, very accurate and high output impedance current output stage (COS) with extremely high output current drive capability is proposed in this paper. The principle of operation of this unique structure is discussed, its most important formulas are derived and its outstanding performance is verified by HSPICE simulation in TSMC 0.18µm CMOS, BSIM3, and Level4...

The strategic intent of the African Union is to develop a “Smart Integrated Electric Power Super Grid” driven by modern tools and advances in high-voltage direct current (HVDC) engineering flexible alternating technology systems (FACTS), which central supporting Africa’s sustained economic growth development. southern region, including South Africa, beset critical challenges perennial load-shed...
