President Reagan proposed $18.
6 million of the budget for this year\'s fiscal year is used by the National synchronous accelerator light source at Upton Brookhaven National Laboratory, but the president\'s plan, Congress, is not always available.
Martin Bloom, deputy director of the lab, said,down $17.
The 6 million light source budget announced last week \"is something we can stand\", but the lab wants to get the other half --
Millions of dollars from the Department of Energy are used to accelerate change, making the already brightest light in the world 100 to 10,000 times brighter.
Two lights to upgrade the device-
The production ring will trigger a series of new experiments, from medicine to microchips, where scientists can take a close look at the molecular landscape of unusual materials and possibly take three

By adding a strong state, the brightness of the beam will be enhancedof-the-art magnets. Dr.
If additional DOE funds are in place, they want to install all the magnets by August, Blume said.
The increased brightness is like increasing the brightness of the light bulb that illuminates the room;
The brighter the light, the more details you can see.
To improve the resolution of the beam.
Two points that still look separate near the line-
Maybe only 500 (
Angstrom is the width of the Atom).
The improvement of resolution can make such experiments possible, for example, let two physicists-Janos Kirz of the State University of New York at Stony Brook and Harvey Rarback of Brookhaven-create living cells to give biologists a close understanding of the function of cells.
This is something you can\'t do before, doctor.
Rarback said that because it may take several weeks to make a holographic photo of a living cell before, by then, the cell will die for a long time.
\"We hope that the same photo taken in the past for an hour should take us 10 seconds. \'\'J. B.
Hastings, who is responsible for the research and development of the synchronous Accelerator Center, said that the increase in brightness will have a profound impact on the experiment, but the specific impact is not clear.
He said: \"In science, it is very important when you have 10 times the ability to do something.
\"The new magnet is part of the $24 million Phase 2 construction of three projects --year-
Old synchronous accelerator center
More than 70 centers
Time\'s staff and hundreds of external researchers have become Brookhaven\'s most important operation since cutting funds for atom.
Smasher project called Isabel.
So far, the accelerator center has cost more than $100 million.
About $12 million in funding for the second phase of the center will be put into the magnet, known as the volatility and swing, and into the new \"beam line, this is the opening in the synchronous accelerator ring, allowing the experimenter to use the generated light.
There are two synchronous accelerator rings in the center.
An octagonal UV or UV ring produces light from the visible to the UV area. The 16-sided X-
High ring-
From the far end of the ultraviolet spectrum, through X-
Almost a gamma ray.
Both rings are electronic beams.
The magnets in every corner force the electrons to turn.
When electrons turn, they emit energy in the form of light.
The new magnets inserted into the straight part of the ring will create a magnetic field that forces the beam to swing or undulate by additional rotation, making them emit more light.
Sound waves pile up with each other, increasing the brightness of the beam.
Hank Xie, the engineer in charge of the advanced magnets, said the center waited until Phase 2 to add the magnets because it would take several years for researchers to learn the capabilities of the basic synchronous accelerators.
Six years ago, the center began designing magnets and making them on site.
Basic technology has been around for at least a decade, but many improvements were only possible a few years ago.
Synchronous radiation was a hassle at first.
This was discovered in particle physics, when researchers noticed that the light emitted by the particle beam interfered with the experiment.
They soon realized
Not as concentrated as a laser, but covering a wider spectrum
Great research potential.
Therefore, the birth of the synchronous accelerator is to reveal rather than crush the atom.
The short-wave length of the synchronous accelerator light shows the atomic arrangement and the electronic state, and the beam is so strong that it is emitted in an instant through the experimental sample, other methods are allowed to be used to complete the reading within a few hours or days.
This is the gospel in the fields of materials science, catalysis, medicine, geology, physics, biology and chemistry.
The military is using a synchronous accelerator for space research on strategic defense plans.
The defense system, commonly known as \"Star Wars\", and industry is interested in its potential to etching extremely compact microchips in a process called soft X-Ray exposure
There are five accelerator centers in the United States: Surf II at the National Bureau of Standards in Gaithersburg, Maryland. ;

Chess at Cornell University in Ithaca, two rings at Stanford University in California, called PEP and SPEAR, and Brookhaven.
The center of the Soviet Union is outdated, while the center of Europe and Japan is advanced.
Due to the cost and commercial potential of synchronous accelerator technology, these centers are usually funded and operated by government, business and academic consortia.
The 70 research participants at the Brookhaven center included 42 universities, 14 companies and 14 government laboratories.
Since each of the Sync Accelerator centers is unique, it is difficult to compare.
Physics experiments are unattractive because of their low power, and because of its ideal spectral range, they may be the perfect choice for chemical experiments.
Michael notek, director of the Brookhaven center, takes the Cornell chess accelerator center as an example.
It\'s stronger than Brookhaven\'s, he says, \"so when you get into very high energy, they win a huge win . \".
However, Cornell\'s beam is brighter and more chaotic than that of Brookhaven.
The main advantages of Brookhaven are the brightest light and the largest number of available beams;
About 50 people, by contrast, the closest competitor to West Berlin\'s Bessie is about 35.
The number of Brookhaven users doubled in two years.
Noteck expects more than 1,000 teams to work there in the next fiscal year.
Mixed popularity-
Potential users may have a long wait to use the beam line.
David Huber, director of the University of Wisconsin Synchronous Radiation Center, said that\'s one of the reasons why Wisconsin is a better place to develop the country\'s potentially lucrative soft X

\"Actually, the only place for the project is Wisconsin,\" he said . \".
\"I think we have set aside five bundles for this purpose.

Noteck said this was mainly due to the small opening at the beginning of the beam.
The smaller the opening, the brighter the beam.
Brookhaven\'s beam is very small, about half a millimeter high, less than 2mm wide.
Although the beam of Bessie is small, there is a bigger problem of instability. Knotek said.
Arthur Bienstock, director of the synchronous accelerator at Stanford University, disagrees with Brookhaven\'s claim to have the brightest light.
He said pep x at Stanford
When running with a certain amount of energy, the light ring \"is at least 10 times higher than any other beam line in the world \". Mr.

Unlike the US synchronous Accelerator Center, which has been plagued by construction delays and cost overruns, Japan is usually ahead of schedule, according to the doctor.
