Effects of Cavity Pre-Detuning on RF Power Transients at Injection into the LHC / Karlsen-Bæck, Birk Emil (CERN ; Rome U.) ; Argyropoulos, Theodoros (CERN) ; Butterworth, Andrew (CERN) ; Calaga, Rama (CERN) ; Karpov, Ivan (CERN) ; Timko, Helga (CERN) ; Zampetakis, Michail (CERN)
At injection into the LHC, the RF system is perturbed by beam-induced voltage resulting in strong RF power transients and the instant detuning of the cavities. The automatic tuning system, however, needs time for the mechanical compensation of the resonance frequency to take place. [...]

Numerical Models and Interplay of Intrabeam Scattering with Incoherent Effects for High Brightness Circular Accelerators / Zampetakis, Michail
Future and existing circular accelerators require high beam brightness, which can be limited by collective effects such as space charge (SC) and intrabeam scattering (IBS) [...]

Machine learning-based extraction of longitudinal beam parameters in the LHC / Iliakis, Konstantinos (CERN) ; Karlsen-Bæck, Birk Emil (CERN) ; Trad, Georges (CERN) ; Timko, Helga (CERN) ; Zampetakis, Michail (CERN) ; Argyropoulos, Theodoros (CERN)
Accurate knowledge of beam parameters is essential for optimizing the performance of particle accelerators like the Large Hadron Collider (LHC). An initial machine-learning (ML) model for the reconstruction of the longitudinal distribution has been extended to extract the main parameters of multiple bunches at LHC injection. [...]

Modelling intra-beam scattering in the LHC for longitudinal beam loss studies / Zampetakis, Michail (CERN) ; Karlsen-Bæck, Birk Emil (CERN ; Rome U.) ; Timko, Helga (CERN) ; Iliakis, Konstantinos (CERN)
In the Large Hadron Collider (LHC), intra-beam scattering (IBS) is one of the main drivers of longitudinal emittance growth during the long injection plateau. With the halo of the longitudinal bunch distribution being close to the separatrix, IBS consequently drives beam losses by pushing particles outside the RF bucket at the flat-bottom. [...]

Correlating start-of-ramp losses with beam observables at blat-bottom in the LHC / Karlsen-Bæck, Birk Emil (CERN ; Rome U.) ; Salvachua, Belen (CERN) ; Timko, Helga (CERN) ; Zampetakis, Michail (CERN) ; Morales Vigo, Sara (CERN)
Power limitations are expected at injection energy for the main Radio Frequency (RF) system due to the doubled bunch intensity in the High Luminosity (HL-) Large Hadron Collider (LHC) era. One way to overcome these power limitations is to reduce the capture voltage. [...]

Development of numerical tools for intra-beam scattering modelling / Soubelet, Felix (CERN) ; Bartosik, Hannes (CERN) ; Kostoglou, Sofia (CERN) ; Paraschou, Konstantinos (CERN) ; Zampetakis, Michail (CERN) ; Iadarola, Giovanni (CERN)
Intra-beam Scattering (IBS) is one of the main mechanisms of emittance blowup and performance deterioration in the Large Hadron Collider (LHC) accelerator complex. It is particularly relevant since the recent upgrades across the injector complex to reach the high brightness beams of the High Luminosity LHC (HL-LHC) era have been implemented. [...]

Chaos Map Analysis of Particle Stability in Accelerators / Zampetakis, Michail
It is well known that the combination of space charge and lattice imperfections can put the beam stability at stake when it has to survive for a large number of turns [...]

Advances on LHC RF Power Limitation Studies at Injection / Timko, Helga (CERN) ; Argyropoulos, Theodoros (CERN) ; Calaga, Rama (CERN) ; Catalán Lasheras, Nuria (CERN) ; Iliakis, Konstantinos (CERN) ; Karlsen-Bæck, Birk Emil (CERN ; Rome U.) ; Karpov, Ivan (CERN) ; Zampetakis, Michail (CERN)
The average power consumption of the main RF system during beam injection in the High-Luminosity Large Hadron Collider is expected to be close to the maximum available klystron power. Power transients due to the mismatch of the beam and the action of control loops will exceed the available power. [...]

Modelling the longitudinal impedance for the Large Hadron Collider (LHC) has been a long-standing effort, especially in view of its High-Luminosity (HL) upgrade. The resulting impedance model is an essential input for beam dynamics studies. [...]
