The MP3 workshop organization comprises two phases: (1) virtual meetings of four working groups (WGs) focused on the scientific topical areas with WG leaders listed below; and (2) an in-person workshop to discuss and prioritize the top science goals and corresponding experiments identified by the working groups.

The figure below illustrates the MP3 workshop process. This notional timeline will be subject to change as the process moves forward and adapt to conditions relative to the COVID-19 pandemic.

Chairs and WG leaders will first establish the processes and tools for the next stages that include the means for:

  • setting dates and times for WG meetings that do not conflict so individuals may participate in more than one, if desired,
  • maintaining MP3 participants contact information,
  • holding virtual meetings (probably Zoom),
  • collaborative file sharing (probably Google Drive), and
  • establishing channels for WGs and workshop organizers to communicate that avoids diverging email threads (possibly Slack or MS Teams).
MP3 workshop process.

A series of monthly virtual WG meetings for each topic will enable sufficient time, broad participation and opportunities for diverse research communities to mix such that the resulting synergy will provide plenty of new ideas and interdisciplinary proposals.

Date Working group
Apr-21 LDNP
Apr-28 LAP
May-12 HFP/QED
May-19 LDNP
May-26 LAP
Jun-3 (note change to Thursday) PAALS
Jun-16 WG cross check #1

WG leaders will identify and invite participants to prepare actionable material for consideration at the MP3 workshop with the aim of broad inclusion and diversity to garner the most promising new ideas for research and development enabled by new generations of powerful lasers.

Working group leaders will solicit white papers for potential scientific goals and flagship experiments, diagnostic needs and strategies, and visions for what a next-generation facility might require. A white paper template will outline inputs required for discussion. Each WG will discuss white papers during virtual meetings with the aim of identifying their scientific impact and readiness with particular attention to defining: coordinated experimental campaigns, theoretical studies, diagnostic- and facility-capability developments, and facility access needed to realize the identified scientific goals.

A WG crosscheck #1 midway through the process will gather MP3 chairs and WG leaders to present progress and start the down-selection process for material to include in a draft workshop report with an eye towards seeking synergies.

Additional virtual WG meetings will focus on preparing and discussing draft report sections and presentations for the in-person workshop. WG crosscheck #2 will review progress and start assembling the draft workshop report. A final set of WG virtual meetings will enable discussions

This process will culminate in an in-person workshop to discuss the top-priority science goals and corresponding experimental programs identified by the working groups and captured in the draft workshop report. The workshop will approve a final report to recommend coordinated plans for U.S. and European research communities. Webcasting the workshop will enable a broad range of individuals and institutions to participate.

A publicly available workshop report will summarize the outcomes and recommend coordinated plans for U.S. and European research communities over the next ten to twenty years. The report will also include material suitable for outreach to the public, such as a press release, fact sheets, posters, and video interviews describing the scientific opportunities and social benefits made possible by multi-petawatt lasers.
