Welcome to the 31st International Symposium on Discharges and Electrical Insulation in Vacuum (ISDEIV)
The International Symposium on Discharges and Electrical Insulation in Vacuum (ISDEIV) is a non-profit, international forum whose purpose is to encourage the advancement of the science and application of electrical insulation and Discharges in vacuum, primarily by conducting symposia for the exchange of scientific information. The Symposium is held biennially for the exchange of results, presentation of progress, and discussion of ideas and challenges for the future of Discharges and electrical insulation in vacuum. Both fundamental and applied aspects are covered. Symposium program consists of invited talks, invited oral contributions, and posters. Minicourses and informal discussions on relevant topics may also be offered in addition to the regular Symposium schedule.
The 31st ISDEIV will be held at Tianfu International Convention Center, Chengdu, China, from Sept. 21 to 26, 2025. The conference will be hosted by Sichuan University, and technically sponsored by IEEE DEIS.
In the meantime, please contact us if you have questions on any aspect of the conference.
ISDEIV is an international forum with a long history of scientific exchange and advancement. Since the first Symposium in 1964, ISDEIV has been held every 2 years. Over the past 60 years, ISDEIV has played an important role in advancing scientific progress, fostering technological innovation and application, and cultivating young talent in the field. All the registered and PRESENTED papers will be included in an IEEE Xplore collection (EI Index), and recommended to submit to an IEEE TPS Special Issue.
