Teaching

In the last years, several Intensive Week Courses took place at the IKP in the framework of the BCGS (Bonn-Cologne Graduate School). An overview of these special courses as well as selected lecture notes is available here.

AGATA Demonstrator

The AGATA Spectrometer is after the experimental campain at the GSI Helmholtzzentrum für Schwerionenforschung moving to the Grand Accèlèrateur National d'Ions Lourds (GANIL) laboratory in France.

The spectrometer comprises an unprecedented amount of fully digitised HPGe channels. Online data processing includes pulse shape analysis to determine the position of each interaction within the array. Gamma ray tracking algorithms are based on this information and track down the path of the detected gamma rays, allowing e.g. precise Doppler corrections and high peak to total ratios.

A variety of experimental methods were employed, like differential RDDS-Plunger measurements, coincidences with reaction products detected by the PRISMA spectrometer (at INFN) and investigation of exotic nuclei delivered by the FRS.

More news and information about AGATA, especially the projects of the Cologne working group, can be found at the local AGATA sites.

Accelerator Mass Spectrometry (AMS)

AMS-symbol

Nach Renovierungsarbeiten am Institut für Kernphysik im Jahr 2010, wurde das Beschleuniger-Massenspektrometer CologneAMS im Mai 2010 geliefert. Die Einweihung des CologneAMS Zentrums an der Universität zu Köln erfolgte 2011, nach erfolgreicher Abnahme des AMS. Ende 2011 wurde zunächst für 14C der Routinebetrieb aufgenommen. Im Jahr 2012 kamen 10Be und 26Al zum Standardmessprogram dazu. Auch erste 244Pu-Messungen wurden erfolgreich durchgeführt.

Collaborations

The new beam profile monitor ikp-bpm

A new detector to measure the beam profile of degraded beams for the HISPEC/DESPEC collaboration at FAIR is being under development at the institute.

The remarkable feature will be its ability to give the user not only a real time profile with a mm resolution, but also the tracking of the current beam. Thereby the ... (read more)

IKP Software Repository

Commonly used IKP-made programms, as the legendary spectra analysing tool TV, can be directly downloaded from our new download directory.

Manuals and documentation – as available – may be found here or in the IKP DokuWiki (login required!).
