Fifty-Five Years of Inextricable Success-Superconducting Radio Frequency (SRF) cavities are vitally central to SRF accelerators, boasting a Q factor about 10⁵ times higher than copper cavities and the capability to produce accelerating fields (Eacc) on an order of magnitude greater than copper in CW. In the 1960s, SRF cavities were delicate instruments used by pioneering scientists in several prestigious labs. Over the past 55 years, the synergy between cryogenics and SRF accelerators has consistently proven mutually beneficial and successful. Today, the landscape has evolved significantly, with potential markets for industrial electron beams reaching $10 billion annually. Various SRF cavities mainly made from Nb (Figure 1)^[1-2] are widely used in high energy physics, nuclear science, FEL, XFEL, synchrotron lights, computer chips, and medical and industrial applications.

When NASA's VIPER (short for Volatiles Investigating Polar Exploration Rover) lands on the surface of the Moon on a mission to better understand the environment where NASA plans to send astronauts as part of the increasingly complex Artemis missions, its journey will be guided by the ingenuity of its human team - and several key tools that use artificial intelligence. From helping the science team choose a landing site at the lunar mountain Mons Mouton, to planning out its path, the VIPER team has developed and used artificial intelligence algorithms to help assess risk and optimize decision making.

NASA’s James Webb Space Telescope observed the exoplanet WASP-80 b as it passed in front of and behind its host star, revealing spectra indicative of an atmosphere containing methane gas and water vapor. While water vapor has been detected in over a dozen planets to date, until recently methane – a molecule found in abundance in the atmospheres of Jupiter, Saturn, Uranus, and Neptune within our solar system – has remained elusive in the atmospheres of transiting exoplanets when studied with space-based spectroscopy. Taylor Bell from the Bay Area Environmental Research Institute (BAERI), working at NASA’s Ames Research Center in California’s Silicon Valley, and Luis Welbanks from Arizona State University tell us more about the significance of discovering methane in exoplanet atmospheres and discuss how Webb observations facilitated the identification of this long-sought-after molecule. These findings were recently published in the scientific journal Nature.

Efforts to build a useful quantum computer are underway, with startup companies competing alongside the big leaders in information technology.

Scientists have been studying fusion for decades with the understanding that if we could replicate the process here on Earth, we could create a virtually limitless clean power resource for the world. Fusion is the same process that happens in the stars, when two light atomic nuclei combine to form a heavier nucleus. At extremely high temperatures and pressures, hydrogen nuclei fuse together to form helium, creating enormous amounts of energy in the process. The challenge on Earth is achieving an energy output that exceeds the energy input, often referred to as Q>1. Achieving self-sustaining fusion energy requires that three conditions are achieved, referred to as the “fusion triple product,” which is the product of (1) plasma density (the number of fuel ions in a given volume), (2) confinement time (how long the hot fuel ions are kept together), and (3) plasma temperature (which provides the energy required for the fuel ions to overcome their mutual electrostatic repulsion and come close enough to fuse). 

Taking the temperature of a sample can be tricky—especially in the regimes of the very small and the very cold. The smaller the sample, the greater the influence the thermometer itself may exert on the measurement. And in the ultracold regime, even tiny amounts of heat can significantly alter the temperature reading.
