Uspekhi Forum on Climate Change and Global Energy Issues
Tuesday January 19, 2021, 7:00 pm

Official Forum Website: http://project3407359.tilda.ws/page15951672.html

Dear esteemed colleagues:

We are pleased to announce the 2021 Uspekhi Forum on Climate Change and Global Energy Issues.

Professor Toshiki Tajima is organizing this important event which will include several international scientists who have been spearheading research on climate change and / or it’s associated energy issues and possible solutions.

This forum will focus on these important issues of the contemporary science and some of it’s impacts on society.  Please check back soon for a link to the official meeting webpage that will include all of the important details.

Background:
In 2019, President Alexander Sergeev of Russian Academy of Sciences (who has been a long time scientific and personal friend of mine) asked if I would organize a scientific forum on climate change and global energy issues.

I felt that this was a very important topic for a forum so I agreed.

The organization of a large, international forum with many leading experts participating is not an easy task, however, by itself this event may become ephemeral after it is over, and thus it is well worth the effort.

Unexpectedly, we faced the COVID-19 pandemic, which made an in-person, large meeting even less realistic, so we determined that the best compromise would be to incorporate the best of the two worlds, i.e. we would organize short in-person forum in Moscow, followed by video-taped presentations of individuals who may not be able to attend in person.

We decided that we would then collect these written review articles and publish them in the Uspekhi based on their presentations.

The current plan is to organize an in-person three hour meeting at the Academy of Sciences in Moscow on January 19, 2021 at 6pm after the RAS Presidium is over. This meeting would include 6 talks, lasting approximately three hours.

We will also solicit video talk contributions that will be uploaded to the Forum website (hopefully in advance). Then we will ask each speaker (including the video speakers) to write their own review article based on their speech. We will publish these papers in a special volume of Uspekhi (with proper reviews as regulated by the journal). The authors will be encouraged to speak / write without restrictions.

We are asking that contributors accept this Forum presentation on a subject of your choice related to the spirit and topical significance on your research on climate changes and / or related energy issues. We leave the choice of topic to the decision of the participants, however, we would be glad to chat with contributors if they have questions, comments, recommendations, etc.

We look forward to hearing your suggestions, communications, and hopefully recommendations, including your own willingness to partake in this Forum.

Sincerely yours,

Toshiki Tajima

About the Conference:
The Optical Society (OSA), in partnership with the American Physical Society’s Division of Laser Science (DLS) present OSA Frontiers in Optics + Laser Science APS/DLS. The conference, which serves also as the OSA Annual Meeting, unites communities from both societies for comprehensive and current research in more than 30 optics and photonics topics and across the disciplines of physics, biology and chemistry. FIO + LS provides attendees from around the world with the opportunity to network, present, learn and connect.

Workshop on beam acceleration in crystals and nanostructures
and
Fermilab Colloquium
June 25, 2019

Meeting Summary download

Professor Toshiki Tajima Presentation download

 The concept of beam acceleration in solid-state plasma of crystals or nanostructures like CNTs (or alumna honeycomb holes) has the promise of ultra-high accelerating gradients O(1-10) TeV/m, continuous focusing and small emittances of, e.g., muon beams and, thus, may be of interest for future high energy physics colliders. The goal of the “Workshop on Beam Acceleration in Crystals and Nanostructures” which took place at Fermilab on June 24 and 25 , 2019, was to assess the progress of the concept over the past two decades and to discuss key issues toward proof-of-principle demonstrations and next steps in theory, modeling and experiment. The Workshop was endorsed by APS DPB, APS GPAP, ICUIL and ICFA ANA. 

The Workshop had 40 participants from 6 countries, representing all relevant areas of research such as accelerators and beam physics, plasma physics, laser physics, and astrophysics. More than 20 presentations covered a broad range of topics relevant to acceleration in crystals and carbon nanotubes
