Master and bachelor theses

Theses within the PI-ICR project at MPIK

PI-ICR project

The mass of a nuclide allows us to large extent to predict the 'life style' of a nuclide – the way how it decays, how long it lives, its shape and so on.

The tool of choice nowadays to precisely measure masses of nuclides – from stable to very short-lived ones – is high-precision Penning-Trap Mass Spectrometry (PTMS).

PTMS of short-lived nuclides is performed using two different ion detection techniques: time-of-flight- (ToF-) and phase-imaging ion cyclotron resonance (PI-ICR) detection. For the cooling of the ions usually buffer-gas cooling is applied.

The PI-ICR project at the Max-Planck Institute for Nuclear Physics has recently been proposed and is considered a test bench for further development of these techniques for next-generation Penning-trap facilities, e.g., MATS at FAIR.


PI-ICR principle

We are currently looking for bachelor and master students for the realization of the PI-ICR project. The students will be involved in:

  1. Investigation of new ideas for the mass-selective buffer-gas ion cooling technique:
    (a) Ion cooling in a collimated helium atomic beam,
    (b) ion cooling in a pulsed helium atomic beam.

  2. Development of a fast helium dosing valve for the ion cooling in a pulsed helium atomic beam.

  3. Development of a Penning-trap mass spectrometer which would allow one to measure with a moderate uncertainty the masses of singly charged ions using mass-selective buffer-gas ion cooling technique and PI-ICR measurement technique.

  4. Development of a control system using the Python programming language.

If you are interested in one or more of these topics, don't hesitate to contact us! We would be happy to show you our labs.
