Researchers Test LAT in D.C.SLAC's involvement with the Large Area Telescope (LAT) didn't end the day it left the lab. In mid-May, when the telescope arrived at the Naval Research Laboratory (NRL) in Washington, D.C., SLAC employees were there to greet the instrument. The crew was part of a larger SLAC contingent that will regularly spend time in D.C. during LAT's pre-launch testing. At NRL, the LAT will undergo tests of vibration, electromagnetic interference, acoustic shock and temperature extremes. The LAT has already passed the first two of these tests. The vibration test subjected the instrument to vibrations that are in excess of the levels it will experience during the rocket launch, while the interference test ensured that the radio waves the LAT emits will not upset the spacecraft, and vice versa. For the acoustic test, NRL will use a facility that blasts the LAT with high intensity sound through the four octaves at 147 decibels to prove that the acoustic shock of takeoff will not harm the instrument. (By comparison, the threshold of human pain is 120 dB.) Finally, the LAT will be subjected to temperature extremes in a vacuum to simulate the harsh environment of space. Read more... |

symmetry magazine: KEK's Ambitious FutureA 45-minute train ride north of Tokyo, Mt Tsukuba stands over a conglomerate of semi-rural agricultural fields dotted with a mix of hamlets and high- tech industry. In the middle of this diverse landscape is one of the world's leading particle physics laboratories, Japan's High Energy Accelerator Research Organization (KEK). KEK is the scientific home for about 700 staff members. In addition, 4000 visitors per year from within Japan and from overseas use the high-energy physics and X-ray light source facilities. A highly collaborative institution, KEK is currently increasing its ties within Japan and abroad to other laboratories, universities, and industry partners as it expands its research efforts. KEK is in the process of building a new proton accelerator facility at its Tokai campus, an hour's drive northeast of its Tsukuba campus; is upgrading some of its existing facilities; and plans a suite of far-reaching experiments for the future.
