X-ray silicon-on-insulator (SOI) pixel sensors, “XRPIX,” are being developed for the next-generation x-ray astronomical satellite, “FORCE.” The XRPIX is fabricated with the SOI technology, which makes it possible to integrate a high-resistivity Si sensor and a low-resistivity Si complementary metal oxide semiconductor (CMOS) circuit. The CMOS circuit in each pixel is equipped with a trigger function, allowing us to read out outputs only from the pixels with x-ray signals at the timing of x-ray detection. This function thus realizes high throughput and high time resolution, which enables to employ anti-coincidence technique for background rejection. A new series of XRPIX named XRPIX6E developed with a pinned depleted diode (PDD) structure improves spectral performance by suppressing the interference between the sensor and circuit layers. When semiconductor x-ray sensors are used in space, their spectral performance is generally degraded owing to the radiation damage caused by high-energy protons. Therefore, before using an XRPIX in space, it is necessary to evaluate the extent of degradation of its spectral performance by radiation damage. Thus, we performed a proton irradiation experiment for XRPIX6E for the first time at Heavy Ion Medical Accelerator in Chiba in the National Institute of Radiological Sciences. We irradiated XRPIX6E with high-energy protons with a total dose of up to 40 krad, equivalent to 400 years of irradiation in orbit. The 40-krad irradiation degraded the energy resolution of XRPIX6E by 25 ± 3 % , yielding an energy resolution of 260.1 ± 5.6 eV at the full-width half maximum for 5.9 keV X-rays. However, the value satisfies the requirement for FORCE, 300 eV at 6 keV, even after the irradiation. It was also found that the PDD XRPIX has enhanced radiation hardness compared to previous XRPIX devices. In addition, we investigated the degradation of the energy resolution; it was shown that the degradation would be due to increasing energy-independent components, e.g., readout noise.

We have developed SOIPIXs based on the CMOS SOI technology for the future X-ray astronomical satellite. SOIPIXs has the event trigger output function implemented in each pixel offers microsecond time resolution and its event trigger function enables to separate celestial X-rays and non-X-ray background by combining the anticoincidence system and to reduce the non-X-ray background that dominates the high X-ray energy band above 5-10 keV. A fully depleted SOIPIXs with a 300-500 um thick depletion layer and back illumination offers wide band coverage of 0.3-40 keV. In order to use XRPIXs in space environment, to investigate the radiation hardness of XRPIXs is important because semiconductor detectors such as XRPIXs and CCDs are damaged by interacting with many cosmic rays which are composed primarily energy protons in orbit. The damage causes the increase of dark current and the degradation of the performance such as the energy resolution of XRPIXs. To evaluate the radiation hardness of XRPIXs, we have carried out the radiation damage test at the heavy ion medical accelerator (HIMAC) in Japan. For this experiment, we used the XRPIX2b-FZ (Takeda et al, 2015) which was the front illuminated XRPIX with 300um thick depletion layer. XRPIX2b-FZ has 144 x 144 pixels and the pixel size is 30um x 30 um. We installed XRPIX2b-FZ in the vacuum chamber and cooled it around -80 C degree. The proton beam flux was much strong for our purpose of this experiment, we set the 3 um thick Au film as a scatterers in the cubic flange in front of vacuum chamber in order to reduce the beam flux. We introduced the scattered proton beam to the two direction of the downstream of the beam line, and one was irradiated to XRPIX2b-FZ in the vacuum chamber and the other was irradiated to the faraday cup connected to the cubic flange to monitor the scattered beam flux. We also obtained the total doze of proton beam using the faraday cup. We irradiated the proton beam to XRPIX2b-FZ until the total irradiation dose reached 10 krad while increasing the irradiation dose and evaluated the performance such as leak current, gain and energy resolution using X-ray from 109 Cd after the proton irradiation of 1 rad, 400 rad, 1 k rad, 4 k rad, and 10 krad. From above experimental results, we found that the gain and the energy resolution was degraded by 0.2 % and 10 % respectively with 400 rad whose equivalent time in orbit was 3.5 years, and the gain and energy resolution became worse by 0.8 % and 32 % respectively after irradiation of 4k rad. We investigated the reason of the degradation of the energy resolution and found the degradation was mainly caused by the increasing the read out noise. We also found the number of bad pixels clearly increased by about 10 times after the irradiation of 10 krad.

The ASTRO-H mission was designed and developed through an international collaboration of JAXA, NASA, ESA, and the CSA. It was successfully launched on February 17, 2016, and then named Hitomi. During the in-orbit verification phase, the on-board observational instruments functioned as expected. The intricate coolant and refrigeration systems for soft X-ray spectrometer (SXS, a quantum micro-calorimeter) and soft X-ray imager (SXI, an X-ray CCD) also functioned as expected. However, on March 26, 2016, operations were prematurely terminated by a series of abnormal events and mishaps triggered by the attitude control system. These errors led to a fatal event: the loss of the solar panels on the Hitomi mission. The X-ray Astronomy Recovery Mission (or, XARM) is proposed to regain the key scientific advances anticipated by the international collaboration behind Hitomi. XARM will recover this science in the shortest time possible by focusing on one of the main science goals of Hitomi,“Resolving astrophysical problems by precise high-resolution X-ray spectroscopy”.¹ This decision was reached after evaluating the performance of the instruments aboard Hitomi and the mission’s initial scientific results, and considering the landscape of planned international X-ray astrophysics missions in 2020’s and 2030’s. Hitomi opened the door to high-resolution spectroscopy in the X-ray universe. It revealed a number of discrepancies between new observational results and prior theoretical predictions. Yet, the resolution pioneered by Hitomi is also the key to answering these and other fundamental questions. The high spectral resolution realized by XARM will not offer mere refinements; rather, it will enable qualitative leaps in astrophysics and plasma physics. XARM has therefore been given a broad scientific charge: “Revealing material circulation and energy transfer in cosmic plasmas and elucidating evolution of cosmic structures and objects”. To fulfill this charge, four categories of science objectives that were defined for Hitomi will also be pursued by XARM; these include (1) Structure formation of the Universe and evolution of clusters of galaxies; (2) Circulation history of baryonic matters in the Universe; (3) Transport and circulation of energy in the Universe; (4) New science with unprecedented high resolution X-ray spectroscopy. In order to achieve these scientific objectives, XARM will carry a 6 × 6 pixelized X-ray micro-calorimeter on the focal plane of an X-ray mirror assembly, and an aligned X-ray CCD camera covering the same energy band and a wider field of view. This paper introduces the science objectives, mission concept, and observing plan of XARM.

We are proposing FORCE (Focusing On Relativistic universe and Cosmic Evolution) as a future Japan-lead Xray observatory to be launched in the mid 2020s. Hitomi (ASTRO-H) possesses a suite of sensitive instruments enabling the highest energy-resolution spectroscopy in soft X-ray band, a broadband X-ray imaging spectroscopy in soft and hard X-ray bands, and further high energy coverage up to soft gamma-ray band. FORCE is the direct successor to the broadband X-ray imaging spectroscopy aspect of Hitomi (ASTRO-H) with significantly higher angular resolution. The current design of FORCE defines energy band pass of 1-80 keV with angular resolution of < 15 in half-power diameter, achieving a 10 times higher sensitivity above 10 keV compared to any previous missions with simultaneous soft X-ray coverage. Our primary scientific objective is to trace the cosmic formation history by searching for "missing black holes" in various mass-scales: "buried supermassive black holes (SMBHs)" (> 10⁴ M_☉) residing in the center of galaxies in a cosmological distance, "intermediate-mass black holes" (10²–10⁴ M_☉) acting as the possible seeds from which SMBHs grow, and "orphan stellar-mass black holes" (< 10² M_☉) without companion in our Galaxy. In addition to these missing BHs, hunting for the nature of relativistic particles at various astrophysical shocks is also in our scope, utilizing the broadband X-ray coverage with high angular-resolution. FORCE are going to open a new era in these fields. The satellite is proposed to be launched with the Epsilon vehicle that is a Japanese current solid-fuel rocket. FORCE carries three identical pairs of Super-mirror and wide-band X-ray detector. The focal length is currently planned to be 10 m. The silicon mirror with multi-layer coating is our primary choice to achieve lightweight, good angular optics. The detector is a descendant of hard X-ray imager onboard Hitomi (ASTRO-H) replacing its silicon strip detector with SOI-CMOS silicon pixel detector, allowing an extension of the low energy threshold down to 1 keV or even less.
