Intensity dependance of the train instability threshold and high pile-up test with 12b trains (MD3294) / Buffat, Xavier (CERN) ; Amorim, David (Universite Grenoble-Alpes (FR)) ; Antipov, Sergey (CERN) ; Bartosik, Hannes (CERN) ; Crockford, Guy (CERN) ; Furuseth, Sondre (EPFL - Ecole Polytechnique Federale Lausanne (CH)) ; Iadarola, Giovanni (CERN) ; Levens, Tom (CERN) ; Metral, Elias (CERN) ; Mounet, Nicolas (CERN) et al.
As signs of electron cloud driven instabilities at top energy were observed in MDs in 2017 even with short trains(12b), an additional experiment was performed in 2018 to assess the intensity scaling of this instability mechanism using high intensity 12b trains available from the existing injector chain, i.e [...]
