International Online Plasma Seminar (IOPS)

MIPSE is happy to support the International Online Plasma Seminar (IOPS). The IOPS is a non-profit international seminar on low temperature plasma science. Its sessions happen bi-weekly via Zoom. Participation is free. The main purpose of the seminar is to make high quality research results in low temperature plasma science available to our community at no cost and interactively, as well as to foster scientific discussion. In this way presentations, that are otherwise only accessible at conferences, are available to anybody - including those who cannot attend classical onsite meetings due to travel restrictions, financial challenges, or other reasons. This has particular relevance during the pandemic, but is also generally important. Often times, students have no access to such presentations, but can attend the IOPS. Following each presentation, questions can be asked by all attendees verbally and the speaker can answer them. Based on the speaker’s written consent, presentations will be recorded and will be made available for on-demand download. If speakers do not agree to do this, the presentations can still be given, but will not be recorded. IOPS speakers can be nominated by anybody and are selected by the IOPS committee, which consists of editorial board members of Plasma Sources Science and Technology (Mark Kushner, Igor Adamovich, Scott Baalrud, David Go, Trevor Lafleur, Julian Schulze).

Current Program of IOPS (updated December 24, 2020)

Presentations begin at 3 pm CET/9 am EST on Thursdays.

For more information, and to request the Zoom link and password, please contact Prof. Dr. Julian Schulze (schulze@aept.rub.de).

Speaker Nominations

Nominations are solicited for speakers for the July-December 2021 sessions of IOPS. Two types of seminars will be presented:

  • Research Highlight (20 minutes + questions): This presentation is intended to summarize a recent publication, and is more highly focused on the topic of the publication.
  • Tutorial/Review (30-45 minutes + questions): This presentation more broadly addresses a topic, and is more like a traditional departmental seminar.

Please submit nominations via this Google form. Deadline for nominations is 31 May 2021.
