“…За последнее время частотный гребень эффективно использовался в эксперименте NIST для исследования давнишней проблемы в наблюдаемом разделении микроструктуры среди различных изотопов лития. Измерения высокого разрешения показали важность квантовой интерференции в мельчайших деталях, а результаты подтверждают сложные вычисления строения атома и потенциал спектроскопии высокой точности для зондирования экзотических ядер [3]. Из второй гармоники эрбиевой частотной гребенки все необходимые длины волны могут охватить диапазон от 780 нм и 795 нм для рубидия и до 1 064 нм и 1 560 для других молекул [9].…”

“…Equation (13) shows that the time distribution of ions ejected out a long square trapping potential with a linear function is proportional to the ion energy distribution and can even be used to measure it (for examples, see Refs 17,18 ). In an ideal case, the release of ions can be uniformly distributed in time to extract a constant rate, R i , over the entire extraction period to produce a square-like (or flat-top) ion distribution (as shown in Fig.…”

Electron beam ion sources and traps (EBIST) produce and trap highly charged atomic ions with an electron beam of high current density. The ions are confined in the radial space-charge potential of the electron beam and a long square-shaped axial electrostatic potential well. An important field of application of EBIST is charge breeding of highly charged ions at radioactive ion beam facilities. There, highly charged radioactive isotopes are accelerated by particle accelerators for experiments in nuclear astrophysics and to study the structure of unstable nuclei. The width in time of the ion pulses ejected from EBIST can often contain too many ions for nuclear physics detection systems to efficiently detect all single radioactive isotopes or related events. Neglecting the influence of ion–ion collisions on the extraction rate, this publication derives, for different initial thermal energy distributions of the trapped ions, the time-dependent trap-opening functions to stretch the time distribution of ion pulses ejected from an EBIST trapping potential for the release of ions at a constant rate over an extended extraction period.

“…Again, this trap is being provided with ions prepared in an EBIT and then charge state selected in a transfer system feeding the external ion trap. Starting from ion trap basics, this line of development has been summarized and put into perspective by the group in a contribution to this Special Issue [67].…”

Abstract:The study of highly charged ions (HCI) was pursued first at Uppsala (Sweden), by Edlén and Tyrén in the 1930s. Their work led to the recognition that the solar corona is populated by such ions, an insight which forced massive paradigm changes in solar physics. Plasmas aiming at controlled fusion in the laboratory, laser-produced plasmas, foil-excited swift ion beams, and electron beam ion traps have all pushed the envelope in the production of HCI. However, while there are competitive aspects in the race for higher ion charge states, the real interest lies in the very many physics topics that can be studied in these ions. Out of this rich field, the Special Issue concentrates on atomic physics studies that investigate highly charged ions produced, maintained, and/or manipulated in ion traps. There have been excellent achievements in the field in the past, and including fairly recent work, they have been described by their authors at conferences and in the appropriate journals. The present article attempts an overview over current lines of development, some of which are expanded upon in this Special Issue.
