The 41st IEEE International Conference on Plasma Science (ICOPS) and the 20th International Conference on High-Power Particle Beams (Beams) will be held jointly in Washington DC on May 25 - 29, 2014, at the Marriott Wardman Park. This joint meeting will cover a range of scientific material, in the fields of both plasma science and high-power particle beams. In addition to the material traditionally covered in these conferences, two mini-courses will also be offered, on the topics of Low Temperature Atmospheric Pressure Plasmas and Atomic and Radiation Physics. These 1.5 day courses will be held on the afternoon of Thursday, May 29, 2014 and all day Friday, May 30, 2014, in the Wilson A and Wilson B meeting rooms.
