17 February - Opening of JUAS Course 2
ESI welcomes 33 Master / PhD students and young professionals for the JUAS course on the Technology and Applications of Particle Accelerators, including 7 “oldtimers” who have just completed the first JUAS course on accelerator physics.
This second 5-week session employs the same innovative pedagogical approach, with a unique mix of lectures, tutorials, seminars, group workshops, practical sessions and laboratory visits, including CERN, the Swiss light source at the Paul Scherrer Institute, the radio-oncology department of Geneva University Hospital and the manufacturer of accelerator components, Bergoz Instrumentation.
7 February - Accelerator Design Workshop with Phil Bryant
Following Phil Bryant’s lectures on “Accelerator design”, he is now helping the students at JUAS to put their learning into practice for two days of computer workshops, during which they will design accelerators to meet user specifications.
Phil is a graduate of University College London who worked at the ISR, headed the CERN Accelerator School, and invented the PIMMS lattice for hadrontherapy synchrotrons during a long career at CERN.
Thanks to Phil for his contributions to the JUAS programme this year.
3 February - Longitudinal Beam Dynamics with Elias Métral & Benoît Salvant
This week at ESI, Elias Metral and Benoit Salvant are giving lectures and tutorials on Longitudinal Beam Dynamics in synchrotrons.
Elias, himself a JUAS alumnus (1996), has worked at CERN on various particle accelerators for over 20 years. He has lectured since 2011 and been deputy director of JUAS since 2014.
Benoît joined the Accelerator and Beam Physics group at CERN in 2006 and has contributed to beam dynamics studies and operation of the LHC complex, particularly on impedance and collective effects. Benoît has been assisting Elias for the JUAS course since 2016.
We thank both of them for sharing their expertise with our students! Here they are pictured with Lise Ribet and Stéphanie Vandergooten (ESI), Philippe Lebrun and Louis Rinolfi (current and former JUAS directors) and Bob Holland (ESI).
31 January - Visit of ESRF Grenoble
The students of the JUAS 2020 course on “The physics of particle accelerators” travelled to Grenoble on 31 January to visit the European Synchrotron Radiation Facility (ESRF ).
After a welcome by Pantaleo Raimondi (Director of Accelerators) and Jean-Luc Revol (Operations Manager who had organized the visit), Jean-Luc presented the accelerator complex and its major upgrade to a “fourth generation” synchrotron facility, which had just produced the record smallest beam emittance in order to achieve unprecedently high brilliance.
The students attended the lectures of Thomas Perron on “Injection and Extraction” and after lunch at the ESRF cafeteria, visited the magnet laboratory, the accelerator control room and some light lines. Many thanks to Laurent, Gael, Sandra, Benoit, Laura, Steven, Flora and Jean-Luc who guided the visits!
27 January - Synchrotron radiation with Rasmus Ischebeck
Over four days of this third week of the JUAS course at ESI, Rasmus Ischebeck will lecture to the students on the building blocks of a storage ring optimized for synchrotron radiation generation and on its applications.
Rasmus is an accelerator physicist who has been working at the Paul Scherrer Institute (Switzerland) for the last decade.
Synchrotrons and storage rings are the most powerful X-ray sources on earth. We thank him for sharing his expertise with all participants in the school!
24 January - Linacs with David Alesini
Linear accelerators (linacs) are ubiquitous as they often provide the first stage of particle acceleration in an accelerator complex. Stand-alone machines provide beams for many applications. Future linear colliders may
be based on very large linacs.
In this the second week of the JUAS course on the Science of Particle Accelerators, we are pleased to welcome David Alesini whose first session yesterday illustrated the basic concepts and parameters of Standing and Traveling Wave Cavities used for acceleration. In today's session he will describe the basic principles of longitudinal and transverse beam dynamics.
David is Head of the “Vacuum group” of the Accelerator division at LNF-INFN, Frascati, and is working on physics and technology of particle accelerators. Thanks to him for sharing his expertise at ESI.
23 January - Cyclotrons with Bertrand Jacquot
The cyclotron concept was among the earliest ideas for accelerating particles to high energy. Many cyclotrons remain in service and are being built today for a wide range of uses including many in hospitals for medical applications.
Today, in the second week of the JUAS course on the Science of Particle Accelerators, we are pleased to welcome Bertrand Jacquot who gave students an overview of the beam dynamics in cyclotrons and the related technical aspects.
After a Ph.D. in nuclear physics from the University of Caen, Bertrand has worked on various aspects of beam optics for the GANIL accelerator facility also in Caen. Thanks to him for sharing his expertise at ESI.
22 January - MAD-X with Guido Sterbini
Over two consecutive days, Guido Sterbini has been giving lectures and hands-on tutorials on MAD-X, the professional software used for accelerator lattice design.
The goal is to give participants at JUAS the opportunity to put into practice the concepts discussed during lectures on transverse dynamics.
Guido is a former JUAS student (2004) and is currently working at CERN mainly on the beam-beam effect in LHC and HL-LHC.
20 January - Seminar by John Jowett
JUAS was delighted to have John Jowett give his first JUAS seminar on “Hybrid collisions in the LHC”, the fruit of his many years passed at CERN working on LEP, LHC and numerous other collaborations.
John graduated in Mathematical Physics from the University of Edinburgh and has Masters and PhD degrees from the University of Cambridge.
Presently JUAS Director Designate, he will take over as Director of the school in Spring 2020 following the annual Advisory Board meeting to be held this year at La Sapienza University of Rome.
17 January - First CERN visit
Participants at JUAS 2020 enjoyed their first afternoon at CERN.
A great programme included an Introduction to CERN and its Accelerator Network, along with guided tours of the Control Center and the LHC Magnets Test Hall, not to mention lunch at one of CERN’s famous cafeterias.
Special thanks to Reyes Alemany and Marta Bajko for their availability and enthusiasm !
13 January - Start of JUAS 2020
ESI is pleased to welcome 22 Master, PhD students and young professionals for an intensive 5-week course addressing the science of particle accelerators.
This 1st JUAS course proposes an innovative pedagogical approach, with a unique mix of lectures, tutorials, seminars, group workshops, practical sessions and laboratory visits.
