Debye size microprobes for electric field measurements in laboratory plasmas
Microelectromechanical systems MEMS have led to the development of a host of tiny machines and sensors over the past decade. Plasma physics is in great need of small detectors for several reasons. First of all, very small detectors do not disturb a plasma, and secondly some detectors can only work because they are very small. We report on the first of a series of small sub-Debye length probes f...
متن کاملLamb Shift in Muonic Hydrogen
The Lamb shift in muonic hydrogen continues to be a subject of experimental and theoretical investigation. Here my older work on the subject is updated to provide a complementary calculation of the energies of the 2p-2s transitions in muonic hydrogen. Introduction The energy levels of muonic atoms are very sensitive to effects of quantum electrodynamics (QED), nuclear structure, and recoil, sin...
متن کاملQuantum electrodynamics in strong electric fields: the ground-state Lamb shift in hydrogenlike uranium.
X-ray spectra following radiative recombination of free electrons with bare uranium ions (U92+) were measured at the electron cooler of the ESR storage ring. The most intense lines observed in the spectra can be attributed to the characteristic Lyman ground-state transitions and to the recombination of free electrons into the K shell of the ions. Our experiment was carried out by utilizing the ...
متن کاملPrecision measurements in helium at 58 nm: Ground state lamb shift and the 1 S-2 P transition isotope shift.
A source of narrow bandwidth (,800 MHz) tunable laser radiation at 58.4 nm has been developed and is applied to record the 11S-21P transition in He and He. From the He transition frequency of 171 134.8936s58d cm21 a fivefold improved ground state Lamb shift of 1.3763s58d cm21 is deduced, in good agreement with the theoretical value of 1.3755s10d cm21. The measured 11S-21P transition isotope shi...
