Burst Intensification by Singularity Emitting Radiation (BISER) is a new mechanism of bright coherent x-ray generation employing high-power femtosecond lasers to drive singularities of multi-stream relativistic plasma flows. We have recently demonstrated that the BISER source can be controlled and stabilized with a tailored plasma density profile (density jump), which is created with a blade inserted into the supersonic gas flow. In this presentation we report on new experimental results obtained with the upgraded J-KAREN-P laser. In particular, we extended the BISER emission up to keV photon energies, and increased the BISER yield in the 60 to 100 eV spectral range up to ~ 1 uJ (10^11 photons) per pulse into the detector acceptance angle of 10^-2 sr.
