Scientists recently upgraded the world’s most powerful X-ray laser and gained the first light,media reported. The linear accelerator coherent light source (LCLS) captures individual atoms and molecules with intense X-ray explosions, and now its second phase of operation has begun. The LCLS is known as the Hard X-Ray Free Electron Laser (XFEL), an instrument that spans several kilometers and can image the smallest objects in more detail than any previous instrument.
To do this, the machine accelerates the electron beams and guides them through a waver. In the process, they emit X-rays, which can be amplified and used in a variety of experiments.
These explosions last only in seconds — a billionth of a second — so they can capture events on an incredibly fast time scale.
Since the first ignition in 2009, LCLS has been used to image viruses, replicate conditions at the center of a star, trigger molecular cascade trigger events, boil water to a strange new plasma state,
Creations may fall on planets such as Uranus and Neptune, such as “Diamond Rain” and so on.
It’s time to upgrade. The second stage (LCLS-II) will double the power of the X-ray and generate more pulses. The initial stage can handle 120 X-ray pulses per second, but ICLS-II will increase that number to 1 million pulses per second.
To achieve this requires a completely new volatility. The original magnets were removed and replaced by two new systems consisting of thousands of magnets. This will allow the electron beam to twist several tons of force without allowing the surrounding structure to move more than one percent of the width of the hair.
By using these new fluctuating systems, scientists will be able to fine-tune the space between magnets more precisely than before, which will allow them to adjust the wavelength of the resulting X-rays.
The new system is now beginning to bear fruit. On July 17, the team launched a beam of radiation from an existing accelerator into a new oscillator, which successfully produced X-rays and achieved full X-ray laser performance by fine-tuning the system.
However, this is only the first step in LCLS-II and the remaining upgrades will be completed within the next two years. With the new oscillator, a new accelerator is also under construction. This will use low-temperature superconducting technology to move electrons at almost the speed of light.
Over the next few weeks, crews will test a series of optics that will adjust the X-rays according to the specific experiments required. After that, over the next six months, it will conduct more than 80 such experiments. The first target of the study will be the SARS-CoV-2 virus.
