18th International Conference on Positron Annihilation

August 19-24, 2018 | Orlando, USA

Please register to attend talks on positron annihilation spectroscopy topics, to say hello to colleagues in person, and visit the Kennedy Space Center as part of your conference registration. Hopefully we'll see a rocket launch while we're there!

Apart from science you'll have plenty of time to relax, meet like-minded people, and to enjoy Florida.

The goal of the conference is to provide a platform for positron researchers from all over the world to present their latest research results, communicate new ideas with colleagues face to face, and to find partners for future collaboration. The conference proceedings will be published in a peer review journal, and the official language of the conference will be English.

Positron School

Positron school will be held on August 19 from 8AM to 6PM prior to our first conference gathering that evening. Since we start early it is reasonable to arrive to Orlando a day in advance on August 18.

School fee is $75. Payment workflow will be posted here soon.

The goal of the school is to present the foundation of important positron technologies as well as to introduce the basics of positron annihilation to scientists from interdisciplinary areas and students. The school will be taught by the top scientists in positron topic and directed towards both experts and beginners.

Presntation Guidelines

Oral presentations

  • Plenary presentations are scheduled for 35 minutes. Presentations are 30 minutes with 5 minutes for questions.
  • Invited presentations are scheduled for 25 minutes. Presentations are 20 minutes with 5 minutes for questions.
  • Contributed presentations are scheduled for 15 minutes. Presentations are 12 minutes with 3 minutes for questions.
  • Standard audiovisual equipment available includes a laptop computer with Microsoft Operating System, a LCD projector, a screen, pointer and a lapel microphone.
  • Speakers should bring their presentations on a USB drive and load their presentation on the session computer at the break preceding their presentation time. (Before the start of the session or during the coffee break.) Powerpoint screen size is 4:3

Poster presentations

  • Poster boards are aligned in a horizontal format. Space allocated for each poster will be 4’ wide by 4’ high. For optimal viewing we recommend posters to be 3’ height by 3.5’ wide in size.
  • Push pins for posting will be available on-site.
  • The following information may assist you in preparing an informative and professional poster display:
  • Print TITLE and AUTHORS in extra-large characters across the top of your display.
  • Display your material in large print so it may be read from a distance. It is important to use text and graphics larger and bolder than those of your manuscript! Be clear and succinct.
  • Each board will be 4’ high by 4’ wide. Your optimal viewing area is 3’ x 3.5’. Boards will accept push pins which will be available.
  • Each presentation will be assigned a board and will be labeled with the number of the paper (e.g. PS01) and the presenting author’s name.
