Laser using the effect of superconductivity

08.02.2018

In Silicon Valley, a place known as the home of all the latest high technology and innovation, construction has begun on a new X-ray laser that is 3 miles (4,8 kilometers) long and uses a mass of superconducting components. This laser is being built at the Fermi National Laboratory's SLAC National Linear Accelerator Laboratory, where the first cryogenic section has just been delivered.

The 12.2 meter (40 ft) sections, called cryomodules, are the "building blocks" of the future LCLS-II laser, which will replace the existing Linac Coherent Light Source X-ray free electron laser (LCLS). The modules have a series of cryogenic units made of niobium. These knots will form electric fields of special shape and great strength, which will accelerate the electrons to almost the speed of light. The LCLS-II laser will produce pulses 10 times brighter than those produced by the LCLS laser. In this case, the pulse repetition rate will be a million times per second.

Half of the new laser's cryomodules will be made at Fermi National Laboratory and the other half at the Thomas Jefferson National Accelerator Center in Virginia. Initially, each of the created modules will be tested individually at the place of its assembly, after which it will be sent to Silicon Valley. These modules will be installed in the tunnel formerly occupied by the SLAC laser equipment, which is 2 miles long and 10 meters below the ground.

Thanks to the amazing performance of the new laser, scientists will be able to study complex materials and processes with unprecedented resolution. The light from the new laser will make it possible to see rare and transient chemical phenomena, study the work of molecules of biological origin, look into the strange world of quantum mechanics and measure the motion parameters of individual components of molecules and even atoms.

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

Three-wheeled electric car 08.05.2002

Single three-wheeled electric car "Sparrow" ("Sparrow") is produced in the United States.

The creators of the car proceeded from statistics: 87% of Americans live at a distance of 29 kilometers or closer from their work, and 93% of those who drive to work in their car drive alone in four-seater or even more spacious cars. This means that a single-seat electric car will be popular.

True, it costs 17 thousand dollars, like a quite decent gasoline subcompact car, but you can save on operating costs. Electricity is cheaper than gasoline, especially for such a light crew (weight without a driver is 612 kilograms). Insurance and parking fees are taken as for a motorcycle.

Thirteen lead-acid batteries after charging for 6 hours provide an hour of driving at a speed of 95 kilometers per hour (maximum speed 110 kilometers per hour).
