Dream beam

I am very happy to announce that was granted en Early Career Research Award by the US Department of Energy, to work on the DREAM beam: Diffraction-limited Radiation Enhancement with Adaptive Mirrors for x-ray coherent beamlines.

Here are some news releases:

They may say I’m a dreamer, but I’m not the only one

Yesterday we received a visit of the speaker of the House, Nancy Pelosi, who came to Berkeley lab for a press conference around the COMPETES act, which aims to bolster STEM education in the US and revive semiconductor manufacturing.

When people ask me what are the answers to some of the challenges that we face, I always say the same thing: Science, Science, Science and Science – Nancy Pelosi

We are quite honored that she chose the Advanced Light Source as backdrop for the announcement. There were also other congresswomen Barbara Lee and Doris Matsui, together with Intel CEO Pat Gelsinger and UC President Michael Drake.

That day felt almost normal – I haven’t seen that many people from the lab in two years. And at the same time, the situation was quite absurd: me right here, among people with the power to change science, at the dawn of WWIII.

EUV lithography makes headlines

EUV lithography is now part of everything – including the chips in your iPhone 12 and beyond. I don’t know if it’s because of the chip shortage, the $50B investment of the US government in semiconductor manufacturing, or the realization that having a nearly monopolistic market with its biggest player in Taiwan, at the mercy of an invasion, but there’s a lot of press on EUV lithography right now (I’ve been talking about my work on the topic at Berkeley Lab here: SHARP and MET5, and shared some thoughts on Moore’s law here.)

Here’s a few pieces:

In this story, ASML is the quiet powerhouse – they have a de facto monopoly (their stock rose 10x over the last 5 years) and they keep expanding (ASML opens new state-of-the-art R&D facility in Silicon Valley.) There’s been some hardball played here, with the US pressuring the European company not to sell their technology with China (Reuters), as if it made any sense.

Besides, I am stoked to see my former colleagues from the Center for X-Ray Optics receive recognition for their work!

I hope we’ll get to develop new techniques with x-rays using diffraction-limited beams to further the advances in semiconductors and microchips – skyrmions, superconductivity, memristors, and so many other cool things!
