Work - OSIRIS / JUNO

I am working on both software and hardware tasks. Being mainly a part of the analysis work group at FZ Jülich, I focus on reconstruction topics in the analysis part. I am also a member of the hardware group that is working at RWTH Aachen, helping with the production of the iPMT system.

Below you can find the main topics I am currently (and will be) working on:

Software topics - Waveform Reconstruction

  • Development of PMT waveform analysis algorithms
  • Implementation of intelligent PMT (iPMT) characteristics into the OSIRIS simulation software
  • Active support of the OSIRIS test and calibration runs after construction (early 2022)
  • Analysis of the first OSIRIS data
  • Analysis of JUNO data

Hardware topics

  • Development and construction of a cleaning facility for OSIRIS parts from Germany
  • Simulation and evaluation of holding structures for the iPMT
  • Supoprting the iPMT production in 2021
  • Potting / glueing support for the iPMT system
  • Active participation in the OSIRIS construction at the JUNO facility in 2021
