Future Spin Physics at JLab; 12 GeV and Beyond

The project to upgrade the CEBAF accelerator at Jefferson Lab to 12 GeV is presented. Most of the research program supporting that upgrade, will require a highly polarized beam, as will be illustrated by a few selected examples. To carry out that research program will require an extensively upgraded instrumentation in two of the existing experimental halls and the addition of a fourth hall. The plans for a high-luminosity electron-ion collider are briefly discussed.Comment: 6 pages; 2 figures; submitted to the Proceedings of SPIN200

Nucleon Electromagnetic Form Factors

A review of data on the nucleon electromagnetic form factors in the space-like region is presented. Recent results from experiments using polarized beams and polarized targets or nucleon recoil polarimeters have yielded a significant improvement on the precision of the data obtained with the traditional Rosenbluth separation. Future plans for extended measurements are outlined.Comment: 12 pages, 6 figures, Talk presented at the Bates25 Symposiu

Nucleon Form Factor Experiments and the Pion Cloud

The experimental and theoretical status of elastic electron scattering from the nucleon is reviewed. A wealth of new data of unprecedented precision, especially at small values of the momentum transfer, in parallel to new theoretical insights, has allowed sensitive tests of the influence of the pionic cloud surrounding the nucleon.Comment: 9 pages; 4 figures; submitted to the Proceedings of the Shape of the Nucleo

Nucleon Form Factors '99

We review recent progress in the experimental knowledge of and theoretical speculations about nucleon form factors, with special emphasis on the large Q2 region.Comment: 4 pages, latex, no figures. Report on the Form Factor session held during the Nucleon99 workshop, Frascati, Italy, June 1999, to be published in Nucl. Phys.

The Super Bigbite Project: a Study of Nucleon Form Factors

A proposed set of instrumentation, collectively referred to as the Super Bigbite project, is presented. Used in three different configurations it will allow measurements of three nucleon electromagnetic form factors GEn, GEp, and GMn with unprecedented precision to Q2-values up to three times higher than existing data

Electromagnetic Form Factors of the Nucleon and Compton Scattering

We review the experimental and theoretical status of elastic electron scattering and elastic low-energy photon scattering (with both real and virtual photons) from the nucleon. As a consequence of new experimental facilities and new theoretical insights, these subjects are advancing with unprecedented precision. These reactions provide many important insights into the spatial distributions and correlations of quarks in the nucleon.Comment: 47 pages, 18 figures, includes corrections and updates to published manuscrip

Black-tailed Godwits (Limosa limosa) in southern Iberia, habitat description and finding colour marked birds from 1 – 26 February 2023:Portugal (Sado, Tejo & Algarve), Spain (Doñana & Extremadura)

In this expedition from 1 to 26 February 2023 we visited the most important areas for Black-tailed Godwits in southern Spain and Portugal during northward migration. Our aim was to resight individual colour marked birds, describe the habitats godwits used and to gain information on threats and opportunities by field observations and meetings with local experts. In this report we present a daily overview of our findings with photos, locations we visited, numbers present and the first conclusions and recommendations.
