Just in case people don't know it already, the Physical Review journals have two journals that are titled with "Physical Review Special Topic" (PR ST). The first is PR ST Accelerators and Beams (PR ST AB). This journal deals with accelerator and beam physics issues. The second is PR ST Physics Education Research (PR ST PER), which is self explanatory.
What is special about these two journals is that they are available for free to everyone. So you could access articles from these two journals with no fee.
