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
