“…The Charge Collection Efficiency was estimated by exposing the detector to the 241 Am sample for 300 s. Thus, several events were detected by the diamond detector during the acquisition time. The output signals were processed by a conventional charge-sensitive electronic chain [12,13,20]. They were first integrated by a charge-sensitive preamplifier (ORTEC 142A).…”

Time-Of-Flight (TOF) technique coupled with semiconductor detectors is a powerful instrument to provide real-time characterization of ions accelerated because of laser-matter interactions. Nevertheless, the presence of strong electromagnetic pulses (EMPs) generated during the interactions, can severely hinder its employment. For this reason, the diagnostic system must be designed to have high EMP shielding. Here we present a new advanced prototype of detector, developed at ENEA-Centro Ricerche Frascati (Italy), with a large area (15 mm × 15 mm) polycrystalline diamond sensor having 150 µm thickness. The tailored detector design and testing ensure high sensitivity and, thanks to the fast temporal response, high energy resolution of the reconstructed ion spectrum. The detector was offline calibrated and then successfully tested during an experimental campaign carried out at the PHELIX laser facility (𝐸 𝐿 ∼100 J, 𝜏 𝐿 = 750 fs, 𝐼 𝐿 ∼ (1 − 2.5) × 10 19 W cm -2 ) at GSI (Germany). The high rejection to EMP fields was demonstrated and suitable calibrated spectra of the accelerated protons were obtained.

“…The time-of-flight measurements were carried out by means of a single crystal chemical vapor deposition diamond detector having a thickness of 50 𝜇𝑚 and interdigited electrodes [40]. Given the expected high level of produced EMPs, the set-up of the diagnostic and the acquisition system was done following the procedure described in Refs.…”

Large-amplitude electromagnetic radiofrequency fields are created by the charge-separation induced in interactions of high-intensity, short-pulse lasers with solid targets and have intensity that decreases with the distance from the target. Alternatively, it was experimentally proved very recently that charged particles emitted by petawatt lasertarget interactions can be deposited on a capacitor-collector structure, far away from the target, and lead to the rapid (nanosecond-scale) generation of large quasi-static electric fields (MV/m), over wide regions. We demonstrate here the generation of both these fields in experiments at the PHELIX laser facility, with approximately 20 J energy and approximately 10 19 W/cm 2 intensity, for picoseconds laser pulses, interacting with pre-ionized polymer foams of near critical density. Quasi-static fields, up to tens of kV/m, were here observed at distances larger than 1 m from the target, with results much higher than the radiofrequency component. This is of primary importance for inertial-confinement fusion and laser-plasma acceleration and also for promising applications in different scenarios.

“…The particle spectrum can be calculated from TOF data, but only supposing the particle species on the basis of physical considerations [4][5][6]. Similarly, magnetic spectrometers relate the particle properties with the deflection, but they are useful only when the particle species is known, for example with electron beams.…”

A: Thomson Spectrometers are devices capable to separate the several particle species (with distinct charge-to-mass ratio and energy) produced by the different regimes of laser-matter experiments. In this work we describe the development of advanced spectrometers for low and medium energy particles. In particular, they are suitable for protons in the 5 keV-2 MeV and 100 keV-10 MeV energy ranges, respectively. The new prototypes of spectrometers have been designed and built to have a high sensitivity and be adaptable to many experimental situations and configurations, and are tailored to the characterization of charged particles and products of nuclear fusion reactions initiated by high energy and intensity lasers. Details on the realized prototypes, on their characterization and testing, together with the first experimental results are discussed.
