The 48Ca beams associated to the heaviest actinide targets available enabled the discovery of the heaviest superheavy elements (SHE) known up to oganesson. Search for new SHE needs now to replace the calcium by 50Ti, 51V and 54Cr. These latter beams are not only more difficult to produce, but they are also needed with significantly higher intensities in order to overcome the drop in SHE production cross sections for new elements.
The present contribution will highlight in a first part the developments made in order to get several particle micro amperes on target using isotopic MIVOC compounds of titanium, vanadium and chromium. The best results obtained will be discussed together with the limitations associated to the vacuum level in the ECR ion source.
In a second part, we will discuss the development of even more intense beams through high temperature inductive micro evens. The oven development will be presented and the first emittance measurements will be discussed. The last section will be devoted to the preparation of highly enriched isotopic metallic pellets of 50Ti and 54Cr.
