Current Drive in a Ponderomotive Potential with Sign Reversal

Current drive in a ponderomotive potential with sign reversal.

Noninductive current drive can be accomplished through ponderomotive forces with high efficiency when the potential changes sign over the interaction region. The effect, which operates somewhat like a Maxwell demon, can be practiced upon both ions and electrons. The current-drive efficiencies, in principle, might be higher than those possible with conventional rf current-drive techniques. It re...

After successful resuscitation the patient was transferred to our institution. On arrival, a non-enhanced brain CTwas performed to assess brain damage, ...

A Novel ±0.5V Ultra High Current Drive and Output Voltage Headroom Current Output Stage with Very High Output Impedance

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...

Energy shifts due to the ponderomotive potential

We show, by simple classical arguments, that the explicit time dependence of the ponderomotive potential causes both a shift and a broadening of the photoelectron lines in high-intensity multiphoton experiments. If the laser pulse is short enough, some of the energy from the absorbed photons will be lost by an electron when it separates from the pulse. Since different atoms are ionized at diffe...
