A new optical device for ion-atom collision experiments with ECR multicharged ion source
- Univ. of Nevada, Reno, NV (United States)
A new optical device for spectroscopic applications in the extreme ultraviolet (EUV) wavelength region has been developed for registration of line spectra from multicharged ions. This device can significantly increase the collection sensitivity of short wavelength radiation emitted from a gas cell subsequent to ion-atom collisions by applying a new glass capillary converter (GCC) device specifically developed for guiding and focusing radiation from a horizontal {open_quotes}cylindrical shaped{close_quotes} source onto a vertical entrance slit of a monochromator. Recently the authors have demonstrated for the first time a considerable enhancement (4 to 5 times) of an EUV signal. In this work they have achieved a coefficient of intensity enhancement of radiation between 5 and 10 by comparing characteristic line intensities with and without their new advanced GCC device. By optimizing further the experimental conditions a coefficient of enhancement of about 20 to 30 is expected. Furthermore, the spectral lines observed have not been displaced if the energy of ion beam is changed. This new experimental approach of line intensity enhancement by glass capillary converter is not only of fundamental importance for ion-atom collision experiments but could also play a fundamental importance for ion-atom collision experiments but could also play a fundamental role in synchrotron radiation applications, plasma diagnostics and imaging of biological systems.
