### Description

The Relic Axion Detector Exploratory Setup (RADES) detector employs rectangular cavities joined by irises to search for axion dark matter between 8 and 9 GHz present in the galactic halo using the haloscope technique. The first results for an axion search in the mass range 34.6738 μeV < $m_a$< 34.6771 μeV using a detector made of 5 sub cavities joined by inductive irises installed at CAST will be presented. The result showcases the potential of using dipole magnets for haloscope searches and opens a possibility to use larger magnet bore size such as foreseenin future axion telescopes as babyIAXO. The physics potential of using taller cavities resonating at 8 GHz and longercavities resonating at 250 MHz is being explored. Also, the designs and prospects (studied by the RADES working group) for such cavities will be shown.
