We cordially invite you to attend the 26^th Symposium on Applications of Plasma Processes (SAPP XXVI) & the 15^th EU-Japan Joint Symposium on Plasma Processing. The symposium will be held at Hotel CHOPOK****, Demänovská Dolina, near Liptovský Mikuláš, Slovakia, between January 29 and February 3, 2027. For several decades, the SAPP Conference has brought together experts from academia, research institutions, and industry. The conference provides a valuable platform for scientific exchange, collaboration, and networking opportunities across generations of researchers, and actively supports early-career researchers and PhD students by offering opportunities to present their results and connect with established experts. While the conference primarily focuses on plasma physics, it also welcomes contributions from related fields, including spectroscopy, experimental physics, molecular physics, and numerical modelling. The symposium organizers and committee members invite you and your family to this exciting event. We are looking forward to your participation, and sincerely hope that you will take this wonderful opportunity to enjoy the enchantment of Low Tatras.
