Universität Hamburg invites applications for a Research Associate for the project
“Determination of the Hierarchy of Neutrino Masses with the JUNO-Experiment” in
accordance with Section 28 subsection 3 of the Hamburg higher education act (Hamburgisches
Hochschulgesetz, HmbHG). The position commences on as soon as possible.

It is remunerated at the salary level TV-L 13 and calls for 50 % of standard work hours per week*.

Duties include academic services in the project named above. Research associates can also
pursue independent research and further academic qualifications.

Specific Duties:
The main task for the holder of the position will be the further development of the 3Dtopological reconstruction for spacious events in large-volume liquid Scintillator detectors.

Here, the portation of our current software to GPUs will have priority. Furthermore, the
software has to be adapted for the usage of realistics signal pulses (waveforms) generated by
the JUNO-PMTs & electronics. Finally, the holder of the position has to provide the necessary
input for the analysis of atmospheric neutrinos in JUNO, which will depend on the tracking and
identification efficiencies for muons and electrons at energies between a few hundred MeV
and a few GeVs.

A participation in the PMT-testing shifts of the JUNO experiment in China is required.

A university degree in a relevant field. Good programming skills in C++. Furthermore desirable
are: Prior knowledge in the programming of GPUs, experience in international collaborations,
excellent scientific performance in data analysis and track reconstruction and good knowledge
concerning large-volume liquid Scintillatior- or Water-Cherenkov-detectors and their

Severely disabled applicants will receive preference over equally qualified non-disabled
