X-ray absorption of cold gas: Simulating interstellar molecular clouds in the laboratory

Autor: Gissis, Itay, Fisher, Amnon, Behar, Ehud

Publikováno v: Phys. Rev. E 104, 015205 (2021)

Galactic and extra-galactic sources produce X-rays that are often absorbed by molecules and atoms in giant molecular clouds (GMCs), which provides valuable information about their composition and physical state. We mimic this phenomenon with a labora

Repumping ground-state population in a coherently driven atomic resonance

Autor: Sinay, Asif, Shuker, Moshe, Firstenberg, Ofer, Fisher, Amnon, Ben-Kish, Amit, Steinhauer, Jeff

We experimentally demonstrate an optical pumping technique to pump a dilute rubidium vapor into the mF = 0 ground states. The technique utilizes selection rules that forbid the excitation of the mF = 0 state by linearly-polarized light. A substantial

Titanium plasma source for capillary discharge extreme ultraviolet lasers

Autor: Shuker, Moshe, Ben-kish, Amit, Fisher, Amnon, Ron, Amiram

Publikováno v: Applied Physics Letters, 88, 061501 (2006).

A technique to generate jets of pure Titanium plasma is presented. A Ti wire is exploded in an Alumina capillary sealed with 1atm. of air inside. The generated plasma emerges from the capillary (to a high-vacuum environment) by ripping a thin Ti foil
