Query: Performance of a focal plane detector for soft X-ray imaging
  spectroscopy based on back-illuminated sCMOS   Spectroscopy focusing array (SFA) and Polarimetry focusing array (PFA) are
the two major payloads of enhanced X-ray Timing and Polarimetry mission (eXTP).
Nested Wolter-\RNum{1} X-ray mirror module is implemented in SFA and PFA to
achive high effective area. When evaluating the properties of the mirror
module, the alignment of the optical axis of the X-ray mirror module and a
quasi-parallel X-ray beam is a prerequisite to ensure the accuracy of the
results. Hence, to assist the alignment of the X-ray mirror module, an X-ray
focal plane detector is designed based on the back-illuminated scientific
Complementary Metal-Oxide-Semiconductor Transistor (sCMOS) sensor
GSENSE6060BSI, one of the largest detection areas, is produced by
\textit{Gpixel Inc}. Then the characteristics of readout noise, dark current,
and split-pixel event properties of the detector are studied with the
self-developed multi-target fluorescence X-ray source in a 100 m long X-ray
test facility. The energy calibration is carried out with the single-pixel
event and the energy non-linearity of the detector is also obtained.
Eventually, the simulation of the eXTP mirror module based on the optical model
is conducted and the alignment test of the Wolter-\RNum{1} X-ray mirror module
designed for \textit{EP/FXT} (Einstein Probe/Follow-up X-ray Telescope) with
"Burkert test" method is shown.
