Call for Expressions of Interests:
DFG Major Instrumentation Initiative (Großgeräteinitiative) 2021

Dear HALO-community,

the DFG has published a call for collaborative initiatives to fund new and innovative instrumentation for major research facilities, please see:

We suggest to prepare and submit a concept proposal for the “Advancement of the Scientific Instrumentation of HALO” within this program to enable funding of the development, testing, and implementation of new instrumentation on HALO.

If you have ideas for new and innovative instrumentation for HALO, please submit a short expression of interests consisting of one page:

  • Describing the instrument concept and illustrating the positive and tangible effects on the relevant fields of research. Please also explain why the instrument is distinct from currently available HALO-instruments, and what the particular relevance, originality, and topicality of research projects is that would necessarily require this advanced instrumentation.
  • Furthermore, you should provide a rough estimate of the expected costs (at this stage the involvement of design organizations is not required), also quantifying follow-up costs and discussing possible contributions of the applying university.

Please submit your expressions of interests (1 page!) until 5 June 2020 to In case of questions, please have a look at the pdf and do not hesitate to contact us.

Best regards,
Manfred Wendisch, Jörg Schmid, and Anja Schwarz

Proposals for the advancements of the scientific and technical infrastructure of HALO

Dear HALO community,

HALO completed the first eight years of operation with outstanding scientific results. Still, advancements of the capabilities of HALO are urgently required, in order to further develop the possibilities to perform world-class scientific investigations with HALO.

Therefore, the HALO consortium will initiate an approach to inquire additional, extensive funding to realize improvements of the scientific and technical infrastructure of HALO (e.g. combined certification of PMS-Carriers and BellyPod, Large Wing Pods, Liquid Cooling System). To prepare this initiative, you are kindly invited to submit proposals in the form of short abstracts. The projects should aim to serve a broader user community of HALO, thus being important for several instruments and/or various members of the HALO community. Furthermore, the budget of the projects should be above the expenses which can be conveniently covered by the annual budget for scientific advancements of HALO.

Please submit your abstract (100 – 300 words) summarizing your ideas to Jörg Schmidt until 28 February 2019. In May/June 2019 the HALO WLA (Scientific Steering Committee) will organize a workshop in Leipzig to discuss the submitted proposals. Based on the outcome of this workshop, the WLA of HALO will pursue the funding of advancements. In case of questions regarding this approach, please do not hesitate to contact:
