Research breakthrough pinpoints aim of ion beams fired at cancer tumors
January 26, 2006Nonsurgical cancer therapy that destroys tumors but leaves healthy surrounding tissue intact could be available at every hospital if research reported this week in the journal Nature eventually comes to fruition.
The Los Alamos National Laboratory Trident laser team, in collaboration with researchers from the University of Nevada, Reno and elsewhere, has succeeded in concentrating the intensity of a laser-driven carbon ion beam into a narrow range.
This work builds upon past research led by the University of Nevada that discovered much higher quality laser proton beams from laser acceleration as opposed to conventional particle acceleration.
Producing carbon ion beams and limiting their spread removes the major impediment to improving such applications as tumor irradiation therapy.
Many technological challenges still have to be met to develop a compact particle generator that could be used in a hospital setting. No clinical trials are imminent.
This research also opens up opportunities for advances in nuclear fusion applications.
The article, "Laser acceleration of monenergetic MeV ion beams," will be published Jan. 26. This research was supported by the Los Alamos National Laboratory Directed Research and Development program. The University of Nevada was also supported by the Department of Energy's National Nuclear Security Administration through the University of Nevada.

Ion Beam Current Events and Ion Beam News RSSTheoretical nuclear physics in China
In recent years several Large-Scale Scientific Facilities (LSSF) for nuclear, hadronic, and particle physics have been upgraded and constructed in China.
The photonic beetle
Researchers have been unable to build an ideal "photonic crystal" to manipulate visible light, impeding the dream of ultrafast optical computers.
Smaller is Stronger - Now Scientists Know Why
As structures made of metal get smaller - as their dimensions approach the micrometer scale (millionths of a meter) or less - they get stronger. Scientists discovered this phenomenon 50 years ago while measuring the strength of tin "whiskers" a few micrometers in diameter and a few millimeters in length.
Doping technique brings nanomechanical devices into the semiconductor world
With the help of a device capable of depositing metals an atom at a time in the materials used in computer chips, a team of University of Wisconsin-Madison engineers has successfully blended modern semiconductor technology and nanomachines.
Nanoparticles unlock the future of superalloy metals
Sandia National Laboratories is pioneering the future of superalloy materials by advancing the science behind how those superalloys are made.
Super small nanoelectrodes can probe microscale environments
Investigating the composition and behavior of microscale environments, including those within living cells, could become easier and more precise with nanoelectrodes being developed at the University of Illinois.
Super-thin Filter, 50 Atoms Thick, Sorts Individual Molecules
A newly designed porous membrane, so thin it's invisible edge-on, may revolutionize the way doctors and scientists manipulate objects as small as a molecule.
Applied scientists create wrinkled 'skin' on polymers
Applied scientists demonstrated a new method for developing wrinkled hard skins on the surface areas of polymers using a focused ion beam.
Stardust particles tell story about birth of solar system
Particulate materials captured from the comet Wild 2 have revealed clues about the birth of our solar system that counter some of the basic theories that the solar nebular is gently collapsing inward to form the sun and the planets.
Long the Fixation of Physicists Worldwide, a Tiny Particle Is Found
After decades of intensive effort by both experimental and theoretical physicists worldwide, a tiny particle with no charge, a very low mass and a lifetime much shorter than a nanosecond, dubbed the "axion," has now been detected by the University at Buffalo physicist who first suggested its existence in a little-read paper as early as 1974.

High Resolution Focused Ion Beams: FIB and Applications by Jon Orloff (Author), Lynwood Swanson (Author), Mark Utlaut (Author) In this book, we have attempted to produce a reference on high resolution focused ion beams (FIBs) that will be useful for both the user and the designer of FIB instrumentation. We have included a mix of theory and applications that seemed most useful to us. The field of FIBs has advanced rapidly since the application of the first field emission ion sources in the early 1970s. The development of the liquid metal ion source (LMIS) in the late 1960s and early 1970s and its application for FIBs in the late 1970s have resulted in a powerful tool for research and for industry. There have been hundreds of papers written on many aspects of LMIS and FIBs, and a useful and informative book on these subjects was published in 1991 by Phil Prewett and Grame Mair. Because there have been so many... |
