 This causes a slightly longer response time, which leads to a slightly lower throughput (750,000 counts per second instead of 1,000,000).However, due to the smaller anode size, this leads to better energy resolutions (down to 123 eV for Mn Kα wavelength).Combined with improved or adapted signal processing, it is possible to maintain the silicon drift detector's energy resolution up to 100,000 counts per second.
