RABIA QINDEEL1, WALID TAWFIK1,2,*
Laser-induced breakdown spectroscopy (LIBS) or laser induced plasma spectroscopy (LIPS) technique has been applied to investigate plasma characterization of pure copper in air. The fundamental wavelength of Q-switched Nd:YAG laser beam was focused on the copper target with intensity of about 6.6 × 108 W/cm² to generate the plasma. The laser intensity was optimized to avoid air breakdown on the target surface. The generated Cu plasma plume was monitored with CCD camera and the emission is analyzed with an Ophir WaveStar spectrometer. The plasma temperature is calculated as 10100 K while plasma density is 5.4 x 1017 cm-3. The CCD observed image of the constructed plasma plume showed that it is oblate shape rather than expected spherical nature. The observed results revealed the spatial distribution of the generated plasma plume expansion towards the laser beam that depends on the plasma properties. The observed ablation profile with the number of laser pulses is also studied..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
