Sandia installs largest Gigahertz Transverse ElectroMagnetic test chamber

SANDIA’S NEW GTEM — Megan Daily and Leonard Martinez (both 1353) prepare for a test in Sandia’s newly installed Gigahertz Transverse ElectroMagnetic (GTEM) test chamber, which manufacturer ETS-Lindgren says is the largest GTEM in the world. The chamber is rated for continuous operation from direct current to more than 1 gigahertz and short duration operation up to electrical fields of 125,000 volts per meter for simulation of nuclear electromagnetic pulse. The large working volume GTEM is the latest addition to a growing suite of state-of-the-art test and experiment capabilities in Center 1300’s Electrical Sciences Group. The GTEM will support ongoing and future nuclear weapons qualification programs, advanced simulation and computing research, weapons systems assessment technologies research, and multiple strategic partnering programs.   (Photo by Randy Montoya)
