The KEK Education and Training Accelerator (KETA) at KEK is a small electron linear accelerator aimed at developing human resources who can contribute to accelerator projects. KETA comprises of an RF source, an electron gun and a 2 m accelerator guide which accelerates beam up to 25 MeV and has three operating modes: a main dump mode, a sub-dump mode and an irradiation mode. The beam commissioning began in spring of 2022 and has been used for the educational purpose. We have been planning to provide accelerator hands-on practicing with KETA for young researchers, such as graduate students of SOKENDAI and other universities, university engineers and industrial people involved in accelerators. This activity is also reported in this paper.
