Description
|
A series of workshops related to the use of Nb3Sn Rutherford cable in accelerator magnets has been launched by CEA and CERN. The goals of this series are:
After the first workshop held in Madrid in November 2017 (1st workshop website ), the 2nd workshop, organized jointly by CEA and CERN will take place in Paris at ESPACE SAINT MARTIN from 11 to 12 October 2018. This edition will focus on:
The Workshop is open to scientists and engineers involved in the development of Nb3Sn accelerator magnets worldwide. Registration is open. The deadline for registration is Wednesday, 10 October 2018.
The Workshop organizers are delighted to invite the participants to a complementary Workshop dinner on Thursday 11 October in the center of Paris (restaurant Le Train Bleu). Please register in the registration form.
