The International Electric Propulsion Conference (IEPC) is a prestigious academic event in the field of electric propulsion. Since its inception, the conference has played a vital role in the research and development of electric propulsion technology. It brings together experts, scholars, engineers, and students from around the world, providing a significant platform to showcase the latest research findings and technological advancements. Through invited talks, product exhibitions, and paper presentations, the conference fosters global exchange and collaboration in electric propulsion, providing valuable support and impetus for spacecraft propulsion technology. Each conference attracts numerous participants who share their research results, discuss technical challenges, and collectively drive innovation and progress in electric propulsion technology.

This year’s IEPC saw the participation of over 700 scholars from around the world. The conference featured 541 oral presentations across 16 themes, including Hall thrusters, subsystems, and advanced concepts, discussing the current state and development trends in the field of electric propulsion.

During the conference, members of the student delegation, with their solid academic foundation and keen research insights, successfully delivered several high-quality presentations. The topics covered included cathode technology, electrospray thrusters, magnetic nozzle optimization, and high-frequency electrostatic instability in Hall thrusters. Details of the presentations are listed in the table below. At the end of their presentations, the students responded to questions from conference attendees and discussed the development of related technologies. These presentations not only demonstrated the deep accumulation and innovative capabilities of the JLPP and ASPEL teams in the field of electric propulsion but also gained unanimous recognition from domestic and international peers through detailed analysis, unique insights, and vibrant articulations. The presentations highlighted the excellent work of the JLPP and ASPEL teams in electric propulsion and enhanced the understanding and awareness of JLPP and ASPEL among international peers.

Postdoctoral and Graduate Student Delegation Members Giving Oral Presentations at the Conference

On June 24, with the conference organizers, the student delegation visited the famous local tourist attraction – Carcassonne Castle. Carcassonne Castle dates back to ancient Roman times and was once a military fortress city. Today, it is a distinctive tourist town flourishing with Western European culture. The castle houses museums, souvenir shops, restaurants, and dessert shops. Delegation members learned about the castle’s history and culture, sampled local cuisine, and experienced the unique cultural characteristics and atmosphere of the area. During the visit, the delegation also engaged in academic discussions with international peers and presented small gifts featuring Chinese cultural elements to local residents and foreign colleagues. This activity allowed delegation members to experience different cultural customs abroad, promoted the understanding of China among foreign friends, and enhanced cultural understanding alongside academic exchange.
