Latest Generation of Silicon Drift Detectors and Readout Electronics

KETEK has further optimized the detector modules with regards to operation in high ambient temperatures and long-time stability. As a result, KETEK SDDs can be operated at ambient temperatures up to +70°C still achieving chip temperatures down to -50 °C leading to optimum detector performance for all detector sizes. The Peltier power is in parallel reduced by more than 50% compared to the previous thermoelectric cooler at a given fixed temperature. Long term stability tests revealed that the vacuum integrity of the new SDD modules is given even at permanent storage temperatures of +80°C.
