Toroidal Anvil Press

Staff scientists at Los Alamos NeutronScience Center, Los Alamos National Laboratory, stand next to TAP98 unit inHIPPO segment during fitting exercise at Los Alamos Laboratory prior to firstrun cycle in 2002.  Yusheng Zhao, Ph.Dwas key in this installation.

Jianzhong Zhang of the Manuel Lujan Jr. NeutronScattering Center (LANSCE-12) sets up an experiment in a toroidal anvil press,one of the high-pressure vessels Zhang and colleague Yusheng Zhao used todiscover the glass formation in pure zirconium metal. The studied material wassitting at the center of the high-pressure cell (held with Dr. Zhang's hands),which can be set to conditions up to 100,000 times atmospheric pressure and to1,500 degrees Kelvin
