Playing Laser JacksAlmost everyone has played the game of Jacks at sometime in his or her life. You throw the ball in the air and have to snatch up the five jacks before the ball hits the ground. You have little time and if you are too slow or too clumsyyou lose! Getting science data from the Linac Coherent Light Source (LCLS) will be much the same: speed and technique will be everything. When the LCLS comes online in 2009, it will be among the most powerful x-ray instruments ever built. And yet it is the very power of this new laser that is presenting some of the most profound research challenges. When focused tightly, the intense laser beam will almost immediately destroy many of the samples it shines on. Can useful data be recorded before a sample is vaporized? Now, thanks to recent collaborative research by scientists at Lawrence Livermore National Laboratory (LLNL), Uppsala University, SLAC, Deutsches Elektronen-Synchrotron (DESY) in Hamburg and several other institutions, an important step toward clearing this hurdle has been taken. We now have experimental evidence that we can get the jacks before the ball falls. Read more... |
