Title: Sivarama Krishnan: Innovator in Extreme Ultraviolet Radiation Technology
Introduction
Sivarama Krishnan is a notable inventor based in Prasanthi Nilayam, India. He has made significant contributions to the field of extreme ultraviolet (EUV) radiation technology. With a total of 2 patents to his name, his work is paving the way for advancements in this specialized area.
Latest Patents
Krishnan's latest patents focus on innovative methods for generating EUV radiation. One of his patents describes a dual pulse driven EUV radiation source method. This method involves a pellet that contains at least one metal particle embedded within a heavy noble gas cluster, which is enclosed in a noble gas shell cluster. The assembly can be activated through a sequential irradiation of at least one first laser pulse and at least one second laser pulse. The first laser pulse generates plasma by detaching outer orbital electrons from the metal particle, while the second pulse amplifies this plasma, triggering a self-amplifying process. This amplified plasma induces inter-orbital electron transitions in heavy noble gas and other constituent atoms, leading to the emission of EUV radiation.
Another patent by Krishnan involves a dual pulse driven EUV radiation source utilizing a droplet comprising a metal core with dual concentric shells of buffer gas. Similar to the previous patent, this method also employs sequential laser pulses to generate and amplify plasma, resulting in the emission of EUV radiation.
