The Global Network for the Atomic and Molecular Physics of Plasmas (GNAMPP) is a consortium of research groups working in the area of fundamental atomic and molecular physics relevant to plasma processes. Its focus is on promoting collaboration and communication between experimentalists and theoreticians to improve the quality and completeness of data used in modelling and interpreting fusion plasmas.
GNAMPP provides a forum for the evaluation, validation and dissemination of data, the benchmarking of relevant modelling codes and the formulation of research guidelines and priorities.
The Scientific Advisory Committee is:
Max-Planck-Institut für Kernphysik (MPIK)
The Crespo group is dedicated to the research of highly charged ions (HCI), developing methods for their production, trapping, and spectroscopy. In particular, it has initiated the field of laser spectroscopy of HCI with conventional lasers and X-ray lasers. The laboratory comprises three superconducting electron beam ion traps (EBITs), several non-cryogenic EBITs, two cryogenic RF traps for sympathetic ion laser cooling, various X-ray/Soft X-ray/VUV spectrometers, and related instrumentation. A VUV frequency comb for precision frequency measurements at high photon energies is currently under construction. The group has recently pioneered the field sympathetic cooling and crystallization of HCI [Schmoger et al. (2015)], searches for transitions sensitive to time-variation of fundamental constants [Windberger et al. (2015)], and, in the last decade, soft X-ray laser spectroscopy using free-electron lasers [Epp et al. (2007), Bernitt et al. (2012)], photoionization and resonant excitation of HCI with synchrotron radiation [Simon et al. (2010), Rudolph et al. (2013)], and optical laser spectroscopy with HCI [Mäckel et al. (2011)]. It closely collaborates with the German national metrology institute PTB (P. O. Schmidt) in the development of frequency metrology using trapped HCI, and with other experimental and theoretical groups at MPIK and elsewhere in the field of precision science with HCI.
