MadMax Mini Workshop

Europe/Berlin
Description

The aim of this mini-workshop is to bring together institutes interested in performing a novel experiment for the search of dark matter QCD axions using the dielectric haloscope idea.

Participation is by invitation only. In order to receive an invitation, please contact Béla Majorovits (bela@mpp.mpg.de).

We want to bring all participants up to date about both, theoretical calculations as well as hardware activities performed so far. We want to discuss the further project plan and hope to attract collaborators for this exciting but challenging project.

There will be a participation fee of 50€, which can be paid either cash upon arrival or by bank transfer to the following account:

Influence of beam shape Axion non-zero momenta: Photon emission angle variations Coherence issue for larger masses (>200 ueV) (de Broglie wavelength comparable to MADMAX size)
