SENJU at J-PARC is a time-of-flight (TOF) single-crystal neutron diffractometer designed for precise crystal and magnetic structure analyses under multiple extreme environments, such as low-temperature, high-pressure and high-magnetic field, as well as for taking diffraction intensities of small single crystals with a volume of less than 1.0 mm down to 0.1 mm. We have recently upgraded some SENJU components, such as sample environment devices, the detector system, and data processing software. These upgrades of SENJU enhance the possibility and accessibility of SENJU, in other words, improvement of versatility. In this presentation, we will introduce the recent upgrades of SENJU for the improvement of its versatility.
