Washington: The x-ray has just got 100 million times brighter, thanks to next-generation light sources like free electron laser oscillator - or the X-FELO.
X-FELO will open up breakthrough scientific opportunities in various research fields. Its characteristics are ideally suited for bulk-sensitive, hard x-ray photo-emission spectroscopy.
Existing technology uses undulators to create bright x-ray beams of spontaneous emission at the Advanced Photon Source (APS) at Argonne.
Much of the research for x-ray free electron lasers has been concentrated on self-amplified spontaneous emission (SASE), which would amplify them by a factor of a million or more in a single pass.
A user of SASE will see x-ray brightness that is about 10,000 times brighter than what the APS is delivering, Argonne's Kwang-Je Kim said.
X-FELO, devised by US Department of Energy scientists, the electron pulse enters an undulator and generates an x-ray that is reflected back into the undulator entrance by crystals and connects with the next electron bunch and again travels back along the undulator. This pattern is repeated indefinitely with the x-ray intensity growing each time until equilibrium is reached.
An X-FELO will enhance the flux by six to eight orders of magnitude, shortening the data collection times by the same factor.
The intensity of individual x-ray pulse from an X-FELO is lower by about three orders of magnitude. However the X-FELO pulse has extremely narrow bandwidth, three to four orders of magnitude narrower than the SASE.
Accordingly an X-FELO user will see a brightness which is about six to eight orders of magnitude brighter than any previously created and three to four orders of magnitude brighter than proposed SASE technology. |
Madonna
If That Is Your Real Name...
by Mike KrumboltzThose born with a thirst for fame as well as an unfortunate (or boring) moniker face a tougher road to the A-list. So it's no wonder that many celebs choose to drop their given name for something a bit more... catchy.
Of course, the gawking public isn't dumb. They know the odds are slim that Sting was born with such an evocative handle. Each week we see an avalanche of searches for celebrity "real names." Folks look up the obvious stage names (Larry the Cable Guy) as well as some that are a tad more subtle (John Wayne). Some of the lookups are met with disappointment. Madonna's real name is, in fact, Madonna. Same deal with Prince.
Below we list the 20 top "real name" searches from the past week. Madonna and Tiger top the list, but you'll find all sorts of actors, athletes, and musicians in the mix. Most people stick with the name they're given. Celebrities are not "most people."
| 1. | Tiger Woods Real Name (Eldrick Woods) | 11. | Bow Wow Real Name (Shad Gregory Moss) | |
| 2. | Madonna Real Name (Madonna Ciccone) | 12. | Soulja Boy Real Name (DeAndre Ramone Way) | |
| 3. | Lil' Wayne Real Name (Dwayne Carter Jr.) | 13. | Triple H Real Name (Paul Michael Levesque) | |
| 4. | Miley Cyrus Real Name (Destiny Hope Cyrus) | 14. | Bono Real Name (Paul Hewson) | |
| 5. | Coco Crisp Real Name (Covelli Crisp) | 15. | Sting's Real Name (Gordon Sumner) | |
| 6. | Hilary Banks Real Name (played by Karyn Parsons) | 16. | Jay-Z's Real Name (Shawn Carter) | |
| 7. | Gene Simmons Real Name (Chaim Witz) | 17. | Tila Tequila Real Name (Tila Nguyen) | |
| 8. | Hulk Hogan Real Name (Terry Bollea) | 18. | Marilyn Manson Real Name (Brian Warner) | |
| 9. | Larry the Cable Guy (Daniel Lawrence Whitney) | 19. | John Wayne Real Name (Marion Morrison) | |
| 10. | Ray Stevens Real Name (Harold Ray Ragsdale) | 20. | Prince's Real Name (Prince Rogers Nelson) |
