The Young Generation Network (YGN) was officially established as part of the International Radiation Protection Association (IRPA) in the spring of 2018. Since then, it has been dedicated to a variety of activities to promote communication, collaboration and professional development of students and young professionals in the area of radiation protection and its allied fields. This article reports our recent activities from the middle of 2018 to the beginning of 2021, with highlights on some important events: (1) Joint JHPS-SRP-KARP Workshop of Young Generation Network (December 2019 in Japan); (2) Contribution to Nuclear Energy Agency Workshop on Optimization - Rethinking the Art of Reasonable (January 2020 in Portugal); (3) Survey on the impact of COVID-19 on radiation protection among IRPA YGN members (March 2020); (4) Contribution to IRPA15 (January-February 2021; online). The discussion and insight obtained from each activity are also summarized. The IRPA YGN will aim to achieve its on-going activities and continue to follow the ways paved in the Strategic Agenda and despite the challenges raised by the COVID-19 pandemic. Namely, running an international survey (for example, on the usage of social media in radiation protection, and on the long-term consequences of the COVID-19 pandemic), engaging national YGNs, extending the network, finding new relationships with networks with an interest in the young generation and participation in (remote) events will be aspired for.

For the main linac of ERL, high loaded Q (QL) operation is desirable to reduce the input generator power. In such operation mode, the suppression of the micophonics is important to stabilize RF amplitude and phase. One of reasons which causes microphonics is mechanical vibration, which changes the cavity frequency. The vibrations of the cavities, the cryomodule and the floor were investigated and compared with the microphnics data taken during cERL operation.

We evaluated a slidejack tuner adopted as compact ERL Main Linac tuner. The tuner compensates the frequency by extending a cavity. Tuning is driven by two system, piezo and slidejack system. Slide-jack mechanism with long stroke drives coarsely piezo adjust precisely and fast. We tested performance of the tuners on operation.

We developed ERL main linac cryomodule for Compact ERL (cERL) project, which was constructed in KEK. The module includes two 9-cell L-band superconducting cavities. After construction of cERL recirculation loop, beam operation was started. First electron beam successfully passed the main linac cavities. After adjusting beam optics, energy recovery operation was achieved. Main linac cavity was enough stable for ERL beam operation, however, field emission was a problem for long term operation.

Since its establishment in 2018, the Young Generation Network (YGN) has been dedicated, with support of the International Radiation Protection Association (IRPA), to a variety of activities to promote communication, collaboration and professional development of students, young professionals and scientists in radiation protection and its allied fields. This presentation will first report on the activities performed from the middle of 2018 to 2022, with highlights on some important events, collaboration and publications. The discussion and insight obtained from each activity will be summarized and used to inform how the IRPA YGN will aim to achieve its on-going activities and continue to follow the ways paved in the Strategic Agenda 2022-2024 and despite the very specific challenges faced by a "young generation network". Namely, running international surveys (for example, on the usage of social media in radiation protection, or on the long-term consequences of the COVID-19 pandemic), engaging national YGNs (for example in contest and discussion about the future of the radiation protection profession), extending the network, finding new relationships with networks with an interest in the young generation and participation in (remote) events will be aspired for.
