Important information for oral and poster presentations
Oral presentations
  • Plenary/invited/oral presentations will be 60/20/15 minutes long (discussion included), respectively.
  • There will be a computer available at the conference to display PDF presentations (Microsoft PowerPoint and Keynote will also be available, however note that file format/missing fonts conflicts may occur). Using a personal laptop is also possible (screening tests are advised, contact the local organising committee for more information at the conference).
  • The projector in the conference amphitheater will only be able to display in a 4:3 format (i.e. using 16:9, widescreen slide format is discouraged).
Poster presentations
  • Posters should be printed in A0 format, portrait orientation.
  • Before the poster session, poster contributions may me introduced in a flash oral presentation (90 seconds). Those who wish to give a flash presentation about their work and did not fill the abstract submission accordingly should contact us at exhilp at More information about the flash presentations will be made available soon on this website.
  • A number tag is attributed to each poster, which identifies the board on which they should be displayed. Pins/tape will be available.
  • Posters should be put up by their owners on Tuesday (September 5th), preferably before the afternoon sessions.
  • There are several printing shops that you can use to print your posters in loco: two inside the campus (LTIDECivil and LIT-DEQB) and another one very close to it (2 minutes walk, ZoomCopia). All websites are in portuguese, but we hope you can find all the information you need. We can also help you on site to find these printing shops.
Flash presentations

People presenting posters at ExHILP will be able to deliver flash oral presentations (90 seconds long) before the poster session in order to introduce their work. This is an excellent opportunity to bring attention to posters and increase their impact in the following session. Those who wish to present their poster work in a flash presentation should let the ExHILP local organising committee know of their intention before August 28th at exhilp at Important information about the flash presentations:

  • Flash presentations will be 90 seconds long.
  • No time will be available for discussion at the flash presentations session, as it should happen momentarily after it in the poster session.
  • It will be possible for participants to project one slide (and one slide only) during the flash presentation. This slide should be sent to the conference organisation (exhilp at in PDF format before September 5th. Using a personal laptop will not be possible in the flash presentations session.
  • The projector in the conference amphitheater will only be able to display in a 4:3 format (i.e. using 16:9, widescreen slide format is discouraged).

Social program

The social program of the second conference on Extremely High-Intensity Laser Physics (ExHILP) will happen on Wednesday, September 6th at 4pm, and will be a 2.5 hours tour in Lisbon on Eco Tuk-Tuks. The tour will cover the locations of some of the iconic monuments, plazas, neighbourhoods and viewpoints of Lisbon. There will also be food and wine tasting points in the tour, with some Portuguese specialties. The tour will have a cost of 30€/person, that should be paid in cash at the conference on-site registration.
