Abstract

We describe results from recent efforts to enhance the performance of CCDs to both low- and high-energy soft x rays. For improved low-energy (E<500 eV) sensitivity we show that a low-temperature surface treatment on back-illuminated devices results in generally better performance than that achieved on devices flown on Chandra, which had a more process-intensive high-temperature treatment. For improved high-energy response we describe a design approach for MOS CCDs that allows high substrate biases for deep depletion (>160 μm) and thus improved x-ray detection for E>5 keV.
