“…Information about the energy released in each track can be inferred from the track size. 4 An improvement to this technique was the use of a microchannel plate ͑MCP͒ followed by a phosphor screen, as a replacement for the CR39 sheet. 3 By combining a CR39 sheet and a thinly collimated Thomson parabola, one can produce several sets of tracks, arranged into curved geometrical loci ͑see Fig.…”

Triggered by the need of a detection system to be used in experiments of nuclear fusion in laser-generated plasmas, we developed an imaging technique for the measurement and calibration of the scintillation light yield of scintillating materials. As in such experiments, all the reaction products are generated in an ultrashort time frame, the event-by-event data acquisition scheme is not feasible. As an alternative to the emulsion technique (or the equivalent CR39 sheets) we propose a scintillating screen readout by means of a high performance charge coupled device camera. Even though it is not strictly required in the particular application, this technique allows the absolute calibration of the scintillation light yield.

“…Various detection systems such as photographic film [15][16][17], CR-39 (solid state nuclear detector) [18], image plate [19] and micro channel plates [20], (MCP) have been used for the ion detection systems in the Thomson Parabola Spectrometer. First three detection systems involves complicated processing method and long time to achieve accurate information corresponding to ions.…”

The laser produced plasma based heavy ion source has become an outstanding front end for heavy ion accelerators. Before being implemented in the heavy ion accelerators its detailed characterization is required. For this purpose, a high resolution and high dispersion Thomson parabola spectrometer comprising of Time-of-Flight diagnostics has been developed for the characterization of ions with energy in the range from 1 keV to 1 MeV/nucleon and incorporated in the Laser plasma experimental chamber. The ion spectrometer is optimized with graphite target. The carbon ions of charge states C 1+ to C 6+ are observed in the energy range from 3 keV to 300 keV, which has also been verified by Time-of-Flight measurement. Experimental results were matched with simulation done by SIMION 7.0 code which is used for the design of the spectrometer. We also developed data analysis software using Python language to measure in situ ion's parameters and the results are in better agreement to the experimental results than the commercially available software SIMION 7.0. The resolution of the spectrometer is ∆E E = 0.026 @ 31 keV for charge state (C 4+ ) of carbon.

“…Thomson Parabola (TP) spectrometers are widely useful for this purpose and they are considered the elected detectors for laser-driven beams characterization [11][12][13][14][15][16][17][18][19][20][21][22]. Its working principle is widely described in literature and it is based on the effect of mutually parallel electric and magnetic field acting on a charged particle.…”

Thomson Spectrometers (TPs) are widely used for beam diagnostic as they provide simultaneous information on charge over mass ratio, energy and momentum of detected ions. A new TP design has been realized at INFN-LNS within the LILIA (Laser Induced Light Ion Acceleration) and ELIMED (MEDical application at ELI-Beamlines) projects. This paper reports on the construction details of the TP and on its experimental tests performed at PALS laboratory in Prague, with the ASTERIX IV laser system. Reported data are obtained with polyethylene and polyvinyl alcohol solid targets, they have been compared with data obtained from other detectors. Consistency among results confirms the correct functioning of the new TP. The main features, characterizing the design, are a wide acceptance of the deflection sector and a tunability of the, partially overlapping, magnetic and electric fields that allow to resolve ions with energy up to about 40 MeV for protons.

Thomson parabola ion analyzer for laser-plasma studies

Abstract: A compact, flexible design for a parallel-fields ion analyzer is presented. Accurate ion velocity and charge state measurements can be obtained over a wide range without the need for calibration sources. Etchable cellulose-nitrate foil is used to record individual ion tracks.
