摘要
The pulse shape processor is the onboard digital electronics unit of the Xray microcalorimeter instrument- the soft X- ray spectrometer- onboard the Hitomi satellite. It processesX- ray events using the optimum filtering with limited resources. It was operated for 36 days in orbit continuously without issues and met the requirement of processing a 150 s - 1 event rate during the observation of bright sources. Here, we present the results obtained in orbit, focusing on its performance as the onboard digital signal processing unit of an X- ray microcalorimeter.
