IBWS 2013 is tenth in the series of successful workshops dedicated to high energy astrophysics and supporting ground-based experiments (e.g. robotic telescopes). The workshop will be held in Karlovy Vary (Carlsbad), Czech Republic, April 22 – 25 2013. The IBWS is expected to start with welcome cocktail in the evening, April 22, the scientific sessions will start in the morning, April 23. Originally, the IBWS (INTEGRAL/BART) workshops focused on the work of High energy astrophysics group in Astronomical Institute, Academy of Sciences of the Czech Republic and relevant international collaborators from the field, with strong student participation. Nowadays, the IBWS workshops promote regional collaboration in high-energy astrophysics with emphasis on interface between satellite projects and ground-based experiments (e.g. robotic telescopes).
