Electro-optic frequency combs for high flux X-ray generation via high-intensity laser-particle interactions at CERN
/ Roiková, Eva (CERN ; Uppsala U. (main)) ; Latina, Andrea (CERN) ; Muşat, Vlad (CERN ; JAI, UK) ; Goryashko, Vitaliy (Uppsala U. (main) ; JAERI-RIKEN, Hyogo) ; Granados, Eduardo (CERN)
Electro-optic frequency comb (EOFC) technology has undergone a significant development in recent years, driven by the increasing demand for agile ultrafast optical systems in both scientific research and commercial applications. Advances in integrated and fiber-based GHz modulators operating in the near-infrared (NIR) region have enabled the use of modulation techniques to efficiently generate ultrafast laser pulses with arbitrary repetition rates of up to 10s of GHz and tunable pulse duration down to 100s of fs.

Benchmarking Intrabeam Scattering with RF-Track
/ Desiré, P (CERN ; U. Groningen (main)) ; Latina, A (CERN) ; Mitri, S Di (Sincrotrone Trieste ; U. Trieste (main)) ; Gerbershagen, A (U. Groningen (main))
Intra-beam scattering (IBS) has recently gained significant interest in the community of free electron lasers (FELs), as it is believed to produce an increment in the sliced energy spread (SES), which is detrimental to FEL performance.To control and contain this phenomenon, it is important to include IBS in the design phase of an FEL through appropriate numerical simulation. Most existing codes that simulate IBS were developed for long-term tracking in circular lattices, assuming Gaussian bunches. [...]

Demonstration and characterisation of a novel dual-scattering system for very high energy electrons
/ Robertson, C (JAI, UK ; Unlisted, UK ; Newcastle upon Tyne U. ; CERN) ; Corsini, R (CERN) ; Farabolini, W (CERN) ; Gerbershagen, A (U. Med. Ctr. Groningen, Groningen) ; Korysko, P (JAI, UK ; CERN) ; Latina, A (CERN) ; Malyzhenkov, A (CERN ; Unlisted, CH) ; Dosanjh, M (JAI, UK ; CERN)
This article describes the design and implementation of the first known prototype of a dual-scattering system for the delivery of a uniform VHEE beam with transverse dimensions suitable for pre-clinical and potential future clinical use. The results presented in this article are the first experimental characterisation of beam flattening with dual-scattering foils in the VHEE regime, confirmed with both profile measurements with a YAG screen and radiochromic EBT3 films.

Dual-scattering foil installation at CLEAR
/ Robertson, Cameron (Oxford U.) ; Aksoy, Avni (Ankara U.) ; Bateman, Joseph (Oxford U.) ; Corsini, Roberto (CERN) ; Dosanjh, Manjit (CERN) ; Farabolini, Wilfrid (CERN) ; Gerbershagen, Alexander (Groningen U.) ; Korysko, Pierre (Oxford U.) ; Latina, Andrea (CERN) ; Malyzhenkov, Alexander (CERN) et al.
The CLEAR facility at CERN allows users to receive an electron beam with energy up to 200 MeV, allowing flexibility in intensity, beam size and bunch structures. Separate from the main CERN accelerator complex, it is capable of hosting numerous experiments with rapid installations at two test stands.It would be highly desirable for many applications, but particularly those of a medical nature, to be able to provide a ‘flat’ beam at CLEAR, with a uniform intensity distribution over a significant component of its transverse dimensions.

Introducing a semi-Gaussian mixture model for simulating multiple coulomb scattering in RF-track
/ Stechauner, Bernd (CERN ; TU Vienna) ; Frühwirth, Rudolf (Vienna, OAW) ; Latina, Andrea (CERN) ; Schulte, Daniel (CERN) ; Schieck, Jochen (Vienna, OAW)
Within the context of a design study of a LINAC for ionization cooling, this paper presents the result of incorporating a scattering model in RF-Track (v2.1) for charged particles heavier than electrons. This inclusion enables simulations for applications like ionization cooling channels for muon colliders. [...]

Beam loading effects in standing-wave linacs and their implementation into the particle tracking code RF-Track

Accelerating technology is evolving towards compactness and high intensity. In such a scenario, beam loading effects result in significant energy losses for long trains of bunches. [...]

Intrabeam scattering simulation with a novel hybrid-kinetic Monte Carlo method for linear accelerators
/ Desire Valdor, Paula (CERN ; Groningen U.) ; Gerbershagen, Alexander (Groningen U.) ; Latina, Andrea (CERN)
Recent studies have identified intra-beam scattering (IBS) as one of the processes that can have a significant impact on the beam dynamics of linacs with high-density and low-energy beams, such as in free electron sources (FELs), where IBS appears to be one of the effects that most limits their performance. Most existing simulation codes have been developed for circular lattices or assume Gaussian beams and thus cannot accurately simulate the desired scenario. [...]

Experimental generation of the transversely uniform electron bunches at the CLEAR facility at CERN
/ Malyzhenkov, Alexander (CERN) ; Latina, Andrea (CERN) ; Aksoy, Avni (Ankara U.) ; Robertson, Cameron (Oxford U. ; CERN) ; Dyks, Luke (CERN) ; Burrows, Philip (Oxford U.) ; Korysko, Pierre (Oxford U. ; CERN) ; Corsini, Roberto (CERN) ; Farabolini, Wilfrid (CERN)
Electron beams with a flat-top transverse distribution are highly desired for uniform dose delivery in irradiation applications, like studies of radiation damage to electronics and radiotherapy, as well as for potential applications in the improvement of light sources. In this work, we report on the optimization of the electron photocathode injector parameters which allow such uniform distributions to be reached. [...]
