Between the 31.03. and the 04.04.2014 the Intensive Week Course "Accelerator Mass Spectrometry: Technique and Applications" (Prof. Dr. W. Kutschera et al.) took place at the IKP in the framework of the BCGS (Bonn-Cologne Graduate School). An overview of further special courses 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)


The final parts of CologneAMS have arrived on May 18th 2010 and are presently assembled. A first test operation of the accelerator is planned for early 2011.
Furthermore the second AMS user workshop took place from July 9th to July 10th, 2010. A detailed program can be found here. Potential users could inform themselves about the current status of the facility, the utilisation concept and the possible applications.


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!).
