This paper describes a novel High Purity Germanium (HPGe) detector, specifically designed to address the challenges of ultimate x-ray spectroscopy and imaging applications for synchrotrons. It consists of a multichannel HPGe crystal (monolithic or individual elements) providing new and ultimate X-ray energy resolution level especially at high count rates (reaching 190eV at 6kev and 0.1µs shaping time), and high throughput. The crystals are cooled using a state-of-the-art electrical cryocooler with active vibration cancellation. The use of a cryocooler does not have any negative impact on the detector performance.
