Organisation
Organisation
• 9th (Sun) to 14th (Fri) September• Dan Panorama hotel• 300+ participants• 30 companies• Very well organized– Good timing of sessions
(starting on time, no delays)– Coffee breaks and lunches,
hence lots of communication
Program• Sunday
– Student poster session, reception
• Mon, Tue, Thu – Morning and afternoon presentations – 1 hour of oral posters, 5 min. each– 2 hours poster session
• Wed– Morning presentations– Outing to Jerusalem
• Fri– Morning presentations
Student poster session
Student poster session• “On-line Dispersion-free Steering for the Main Linac of CLIC” by
Jürgen• “Specifications of the Distributed Timing System for the CLIC Main
Linac” by Alexander
Student poster session winner:• “First Demonstration of Optical Frequency Shot-noise Suppression in
Relativistic Electron-beams” by A.Nause (University of Tel-Aviv)– collective Coulomb interaction between the electrons of a cold intense
beam during beam drift– beam charge homogenizes due to the collective interaction, and its
distribution becomes sub-Poissonian– measure sub-linear growth as a function of current of the optical transition
radiation
