Abstract

We describe results from recent enhancements to the performance of charge-coupled devices (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 superior energy resolution compared to that of the 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 (up to 160 μm) and, thus, improved X-ray detection for E > 5 keV.
