- 20/5/2014 Guided tour of the X-ray diffraction line of Elettra - Sincrotrone Trieste (the tour starts at 14.00; the meeting point is the bus stop close to the main parking lot; students can take bus 51, that leaves the bus stop in front of the central train station at 13.40, stops just in front of the physics department a few minutes later, and is scheduled to arrive at 14.00 at Elettra).
