I participated in the JUAS courses in 2012 when I was doing my master in advanced physics in Valencia (Spain). I found all the subjects very relevant, taught by excellent professors and in a great international environment. It is a very complete program and you have plenty of time to get a grip on the different fields of accelerator physics. It is divided into theory lessons, workshops and problem solving sessions. Being able to discuss with experts from the different accelerator physics domains which allows you to understand better some of the topics and satisfy your curiosity. On top, you get the chance to make friends with other students from all around world which you will later meet and work with in the future if you decide to continue in the field! The courses help me very much on the realization of my master project on collimator wakefield studies and motivated me to continue my carrier in accelerator physics.
I strongly recommend the JUAS program for any student considering a career in accelerator physics. From my experience I can assure you that it will be a profitable experience!
In 2013, I started my Ph.D on beam halo collimation and wakefield studies for the Accelerator Test Facility 2 (ATF2) in the framework of the Future Linear Collider (FLC). I successfully defended my PhD in July 2017, and I am currently a fellow at CERN working in the LHC collimation team.
