“…The signal acquisitions carried out by linear monopole antenna [31] and super wide-band antenna [32] placed both inside the interaction chamber, above the target at 30cm from it, and protected by a thick stainless-steel slab, as from Fig.5(c), are shown in Fig.5(a) and in Fig.5(b), respectively. It is well known that it is very difficult to get reliable measurements of EMP by conductive probes when high intensity and energetic lasers are used [1][2][3][4][5][6][7][8][9][10]12]. In fact, big fluctuations were present shot by shot on the measurements, due to background noise on the oscilloscopes caused by bad EMC-shielding of the scope and by spurious coupling of EMP with outside conductor of the coaxial cables.…”

“…In fact, big fluctuations were present shot by shot on the measurements, due to background noise on the oscilloscopes caused by bad EMC-shielding of the scope and by spurious coupling of EMP with outside conductor of the coaxial cables. To resolve these problems, it was necessary to use a delay line to clean the signals, as described in references [33,34]. Fig.…”

“…The main sources of EMP are the return target current flowing through the target holder and the charged particles escaping into the vacuum; both these EMP sources are directly connected with hot electrons escaping the plasma [1][2][3][4][5][6][7][8]. To obtain a complex data set on this process, various probes are employed for observation of return current and EMP emission during 3TW PALS laser pulse-target interaction experiment.…”

Abstract. During the interaction of high intense laser pulse with solid target, a large amount of hot electrons is produced and a giant Electromagnetic Pulse (EMP) is generated due to the current flowing into the system target-target holder, as well as due to the escaping charged particles in vacuum. EMP production for different target materials is investigated inside and outside the target chamber, using monopole antenna, super wide-band microstrip antenna and Moebius antenna. The EMP consists in a fast transient magnetic field lasting hundreds of nanosecond with frequencies ranging from MHz to tens of GHz. Measurements of magnetic field and return target current in the range of kA were carried out by an inductive target probe (Cikhardt J. et al. Rev. Sci. Instrum. 85 (2014) 103507).

“…In particular, the requirements needed to measure the energy and the flux of laser-driven beams are: radiation hardness (>10 12 p/bunch), fast charge collection, due to the intense proton pulse duration of about 10 ns and good signal-to-noise ratio, due to the huge electromagnetic pulse (EMP) which characterizes the laser environment [23]. Moreover, considering the high laser repetition rate (1-10 Hz) at ELIMAIA, the use of detectors able to give online shot-to-shot information of the beam parameters, as energy and intensity, is fundamental in order to monitor and control continuously the beam for applications.…”

Laser-accelerated ion beam diagnostics with TOF detectors for the ELIMED beam line

A: Laser-accelerated ion beams could represent the future of particle acceleration in several multidisciplinary applications, as for instance medical physics, hadrontherapy and imaging field, being a concrete alternative to old paradigm of acceleration, characterized by huge and complex machines. In this framework, following on from the ELIMED collaboration, launched in 2012 between INFN-LNS and ELI-Beamlines, in 2014 a three-years contract has been signed between the two institutions for the design and the development of a complete transport beam-line for high-energy ion beams (up to 60 MeV) coupled with innovative diagnostics and in-air dosimetry devices. The beam-line will be installed at the ELI-Beamlines facility and will be available for users. The measurement of the beam characteristics, such as energy spectra, angular distributions and dose-rate is mandatory to optimize the transport as well as the beam delivery at the irradiation point. In order to achieve this purpose, the development of appropriate on-line diagnostics devices capable to detect high-pulsed beams with high accuracy, represents a crucial point in the ELIMED beamline development. The diagnostics solution, based on the use of silicon carbide (SiC) and diamond detectors using TOF technique, will be presented together with the preliminary results obtained with laser-accelerated proton beams.

“…As one can see from the inset in Figure 12, the EMP is characterized by frequency components from few hundreds of MHz up to 2 GHz. Based on the frequency analysis, the significant noise signal results from the EMP propagation inside the interaction chamber [33,34] and seems to be predominant with respect to the charge signal, affecting the measurement of the total collected charge. Nevertheless, the cumulative integration of the FC signal, as shown in Figure 13, reveals the presence of a charge contribution that, although very small, can be separated by the huge EMP noise contribution [27].…”

Charged particle acceleration using ultra-intense and ultra-short laser pulses has gathered a strong interest in the scientific community and it is now one of the most attractive topics in the relativistic laser-plasma interaction research. Indeed, it could represent the future of particle acceleration and open new scenarios in multidisciplinary fields, in particular, medical applications. One of the biggest challenges consists of using, in a future perspective, high intensity laser-target interaction to generate high-energy ions for therapeutic purposes, eventually replacing the old paradigm of acceleration, characterized OPEN ACCESSAppl. Sci. 2015, 5 428 by huge and complex machines. The peculiarities of laser-driven beams led to develop new strategies and advanced techniques for transport, diagnostics and dosimetry of the accelerated particles, due to the wide energy spread, the angular divergence and the extremely intense pulses. In this framework, the realization of the ELIMED (ELI-Beamlines MEDical applications) beamline, developed by INFN-LNS (Catania, Italy) and installed in 2017 as a part of the ELIMAIA beamline at the ELI-Beamlines (Extreme Light Infrastructure Beamlines) facility in Prague, has the aim to investigate the feasibility of using laser-driven ion beams in multidisciplinary applications. ELIMED will represent the first user's open transport beam line where a controlled laser-driven ion beam will be used for multidisciplinary and medical studies. In this paper, an overview of the beamline, with a detailed description of the main transport elements, will be presented. Moreover, a description of the detectors dedicated to diagnostics and dosimetry will be reported, with some preliminary results obtained both with accelerator-driven and laser-driven beams.
