What is NIF science?

NIF is the world's most precise and reproducible laser system. It precisely guides, amplifies, reflects, and focuses 192 powerful laser beams into a target about the size of a pencil eraser in a few billionths of a second, delivering more than 2 million joules of ultraviolet energy and 500 trillion watts of peak power.

When was the NIF built?

The National Ignition Facility (NIF), became operational in march 2009. Planning began in the early 1990s, and ground was broken for the facility on —12 years to the day before NIF's dedication. NIF is not only the world's highest-energy laser, it's also the largest optical instrument ever built.

What is a fusion laser?

Laser fusion, also known as 'inertial confinement fusion', is a method of initiating nuclear fusion reactions through heating, and compressing, fuel targets in the form of pellets containing deuterium and tritium. It is one of the most-promising approaches to achieving controlled thermonuclear fusion.

What is nuclear ignition?

Fusion ignition is the point at which a nuclear fusion reaction becomes self-sustaining. This occurs when the energy being given off by the fusion reactions heats the fuel mass more rapidly than various loss mechanisms cool it.

What is NIF used for?

What is NIF used for? NIF enables scientists to create extreme states of matter, including temperatures of 100 million degrees and pressures that exceed 100 billion times Earth's atmosphere.

How does the NIF work?

NIF uses lasers to heat and compress a small amount of hydrogen fuel with the goal of inducing nuclear fusion reactions. ... At these temperatures, fusion processes occur very rapidly, before the energy generated in the fuel causes it to explode outward as well.

What is the purpose of NIF?

What is NIF used for? NIF enables scientists to create extreme states of matter, including temperatures of 100 million degrees and pressures that exceed 100 billion times Earth's atmosphere.

How powerful is the NIF laser?

The National Ignition Facility (NIF) -- a laser test facility at Lawrence Livermore National Laboratory in Livermore, Calif. -- is the world's most powerful laser. Though it faces fiscal challenges, NIF is still capable of unleashing a blast with 500 trillion watts of power.

Is cold fusion possible?

Cold fusion is a hypothesized type of nuclear reaction that would occur at, or near, room temperature. ... There is currently no accepted theoretical model that would allow cold fusion to occur.

What are laser used for?

Lasers are used in optical disc drives, laser printers, barcode scanners, DNA sequencing instruments, fiber-optic, semiconducting chip manufacturing (photolithography), and free-space optical communication, laser surgery and skin treatments, cutting and welding materials, military and law enforcement devices for ...

Did NIF achieve fusion?

America's National Ignition Facility measured a record of 70% conversion in their laser fusion experiments. For a brief moment the fusion was self-sustaining. A moment that excites people around the globe.

What is a NIF Respiratory?

Negative inspiratory force (NIF) is a relatively easy bedside test to measure respiratory muscle function and can easily be performed every half hour to hour in difficult cases. Normal is usually greater than 60 cm water. If the NIF is dropping or nears 20 cm water, respiratory support needs to be available.

What is the difference between NIF and NIE?

As a general rule, the Tax ID Number (NIF) of the individuals of Spanish nationality will be their DNI (Spanish National ID) followed by the verification code and for those that are not Spanish nationals, it will be the NIE (Foreign National ID).

What is a normal NIF?

Negative inspiratory force (NIF) is a relatively easy bedside test to measure respiratory muscle function and can easily be performed every half hour to hour in difficult cases. Normal is usually greater than 60 cm water. If the NIF is dropping or nears 20 cm water, respiratory support needs to be available.

What is NIF in banking?

Financial Terms By: n. Note issuance facility (NIF) An agreement by which a syndicate of banks indicates a willingness to accept short-term notes from borrowers and resell these notes in the Eurocurrency markets.

Is Cold Fusion viable?

There is currently no accepted theoretical model that would allow cold fusion to occur. In 1989, two electrochemists, Martin Fleischmann and Stanley Pons, reported that their apparatus had produced anomalous heat ("excess heat") of a magnitude they asserted would defy explanation except in terms of nuclear processes.

What happens if a fusion reactor fails?

If any of the systems fail (such as the confining toroidal magnetic field) or if, by accident, too much fuel is put into the plasma, the plasma will naturally terminate (what we call “disrupt”) – losing its energy very quickly and extinguishing before any sustained damage is done to the structure.

What are 3 types of lasers?

Types of lasers

• Solid-state laser.
• Gas laser.
• Liquid laser.
• Semiconductor laser.

What are the side effects of laser treatment?

Risks

• Redness, swelling and itching. Treated skin may be itchy, swollen and red. ...
• Acne. ...
• Infection. ...
• Changes in skin color. ...
• Scarring. ...
• Turning of the eyelid (ectropion).

How do you give a NIF to a patient?

Measurement of maximal inspiratory pressure (or NIF)

1. Patient must be active, that means breathing spontaneously.
2. Set the Y-axis of the pressure curve manually: Positive 20, negative -120.
3. Set PEEP to 0.
4. Perform an expiratory hold.
5. Measure the minimum of the pressure curve.
