The most powerful laser in the US reaches 2 petawatts, setting new records

ZEUS will open new frontiers in imaging, cancer therapy, and astrophysics



The ZEUS laser facility at the University of Michigan has vaulted the United States to the forefront of high-intensity laser science. In its first official experiment, ZEUS achieved a peak power of 2 petawatts  twice the output of any other laser in the country. Although this burst, more than 100 times the world's total electricity output, lasts only 25 quintillionths of a second, it represents a major milestone in American research capabilities.

"This milestone marks the beginning of experiments that move into unexplored territory for American high field science," said Karl Krushelnick, director of the Gérard Mourou Center for Ultrafast Optical Science, which houses ZEUS. The university describes the facility, constructed for $16 million, as a "bargain" given its scale and potential.

Supported by the US National Science Foundation, ZEUS operates as a user facility, welcoming research teams from across the country and around the world. Proposals for experiments are selected through an independent review process, ensuring that the laser's capabilities are used for the most promising scientific inquiries. Research conducted at ZEUS is expected to advance fields such as medicine, national security, materials science, astrophysics, plasma science, and quantum physics.

The ZEUS system is primarily built from commercial components and incorporates advanced technologies, including a double chirped pulse amplifier and programmable acousto-optic filters that preserve the precise bandwidth and phase required for ultrashort, high-power pulses. The laser can deliver compressed pulses as brief as 20 femtoseconds, enabling a wide range of cutting-edge experiments.

Inside a space roughly the size of a school gymnasium, ZEUS houses three distinct target areas, each tailored to specific research applications. Target Area 2 is designed for experiments involving solid targets and ion acceleration, while Target Area 3 is optimized for laser wakefield acceleration and can measure electron energies up to approximately 5 GeV.

The facility's ability to split its beam allows it to achieve intensities up to a million times greater than a single beam alone, enabling the study of extreme phenomena such as quantum vacuum structures and the creation of matter-antimatter pairs from empty space.

"Explore the Fourth Dimension"

Fourth Dimension   The fourth dimension is a fascinating concept that has captured the imaginations of scientists, mathematicians, and artists for centuries. Unlike our three-dimensional world, which is limited by the linear flow of time, the fourth dimension is a realm of space and time that exists beyond our everyday experience. One way to visualize the fourth dimension is through the use of a hypercube, also known as a tesseract. A hypercube is a cube within a cube, with additional lines and edges connecting the vertices of the two cubes. It's impossible to construct in our three-dimensional world, but it provides a glimpse into what the fourth dimension might look like. Another way to understand the fourth dimension is through the concept of a wormhole, a theoretical passage through space-time that connects two distant points in the universe. A wormhole is like a shortcut through the fabric of space-time, allowing us to travel vast distances in an instant. While there is no de...

Physicists observe a new form of magnetism for the first time

MIT physicists have demonstrated a new form of magnetism that could one day be harnessed to build faster, denser, and less power-hungry " spintronic " memory chips. The new magnetic state is a mash-up of two main forms of magnetism: the ferromagnetism of everyday fridge magnets and compass needles, and antiferromagnetism, in which materials have magnetic properties at the microscale yet are not macroscopically magnetized. Now, the MIT team has demonstrated a new form of magnetism , termed "p-wave magnetism." Physicists have long observed that electrons of atoms in regular ferromagnets share the same orientation of "spin," like so many tiny compasses pointing in the same direction. This spin alignment generates a magnetic field, which gives a ferromagnet its inherent magnetism. Electrons belonging to magnetic atoms in an antiferromagnet also have spin, although these spins alternate, with electrons orbiting neighboring atoms aligning their spins antiparalle...

Green comet to pass Earth, won't be back for another 50,000 years

   visit:  https://hep-conferences.sciencefather.com/ After travelling from the icy reaches of our Solar System it will come closest to the Sun on January 12 and pass nearest to Earth on February 1.   A newly discovered comet could be visible to the naked eye as it shoots past Earth and the Sun in the coming weeks for the first time in 50,000 years, astronomers have said. The comet is called C/2022 E3 (ZTF) after the Zwicky Transient Facility, which first spotted it passing Jupiter in March last year. After travelling from the icy reaches of our Solar System it will come closest to the Sun on January 12 and pass nearest to Earth on February 1. It will be easy to spot with a good pair of binoculars and likely even with the naked eye, provided the sky is not too illuminated by city lights or the Moon. The comet "will be brightest when it is closest to the Earth", Thomas Prince, a physics professor at the California Institute of Technology who works at the Zwicky Transi...
