Recently developed silicon carbide (SiC) detectors have been employed to study pulsed laser plasmas produced by irradiation of a double-stream gas puff target with nanosecond laser pulses. The plasma emitted by a gas-puff target source in the soft X-ray (SXR, λ = 0.1 - 10 nm) and extreme ultraviolet (EUV, λ = 10 - 120 nm) ranges was monitored with silicon carbide (SiC) detectors and compared with a commercial, calibrated silicon (Si) photodiode (AXUV-HS1). Different filters have been used to select the emission in different wavelength ranges from the broad-band emission of the plasma. This work shows the applicability of SiC detectors to measure the SXR and EUV ns pulses from the plasma, useful for monitoring and optimizing the gas-puff laser-plasma sources developed at IOE-MUT, in Warsaw (Poland). Some aspects relative to the plasma stability as well as characterization of the plasma source (i.e. the overall evaluation of the signal and the time trace profile) will be presented and discussed.

Abstract
Recently developed silicon carbide (SiC) detectors have been employed to study pulsed laser plasmas produced by irradiation of a double-stream gas puff target with nanosecond laser pulses. The plasma emitted by a gas-puff target source in the soft X-ray (SXR, λ = 0.1 - 10 nm) and extreme ultraviolet (EUV, λ = 10 - 120 nm) ranges was monitored with silicon carbide (SiC) detectors and compared with a commercial, calibrated silicon (Si) photodiode (AXUV-HS1). Different filters have been used to select the emission in different wavelength ranges from the broad-band emission of the plasma. This work shows the applicability of SiC detectors to measure the SXR and EUV ns pulses from the plasma, useful for monitoring and optimizing the gas-puff laser-plasma sources developed at IOE-MUT, in Warsaw (Poland). Some aspects relative to the plasma stability as well as characterization of the plasma source (i.e. the overall evaluation of the signal and the time trace profile) will be presented and discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
