No. 70 (2017): Status and plans for major US light source facilities

Issue editor: M. A. Palmer, Editor-in-chief: Y. H. Chin

Five well-written articles provide very comprehensive reviews on the status of some of the major light sources in the US as well as their plans for upgrades in the near future.

This issue also includes two articles on the topic of intra-beam scattering (IBS) from the recipients of the 2017 Robert R. Wilson Prize (James Bjorken, Sekazi Mtingwa and Anton Piwinski).

In this issue there are also three workshop/conference reports (EuCARD2 Workshop on the “Status of Accelerator Driven System Research and Technology Development”, the 2017 CLIC Workshop and the ICFA mini-workshop “Beam Dynamics Meets Vacuum, Collimation, and Surfaces.”), one recent doctoral thesis abstract (Feng Su(IHEP)) and four conference/workshop announcements (NOCE 2017: The International Workshop on Nonlinear Dynamics and Collective Effects in Particle Beam Physics, AccApp`17: The 13th International Topical Meeting on the Applications of Accelerators; and BeamBeam2017: The International Workshop on Beam-Beam Effects in Circular Colliders and VHEE17 Mini ICFA Beam Dynamics Workshop).
