The crumpling or crushing of paper, aluminum foil, or even a car fender is an everyday occurrence that is surprisingly rich in new physical and materials principles. UMass researchers Narayanan Menon and Dominique Cambou used X-ray microtomography experiments on foils crushed into a ball to understand their detailed 3D structure.
A slender filament such as a hair from your head or a blade of grass, easily buckles into a folded shape, but when you let it go, it springs back into its original shape. This image, taken by UMass graduate student Gangaprasath and postdoc Joel Marthelot, shows a soft slender filament made of silicone rubber, floating on a liquid surface to slow down the process of straightening out.
A view inside the LUX dark matter detector during construction. At the center is an array of highly-sensitive photomultiplier tubes (PMTs). During operation, this detector volume contains liquified xenon gas of extreme purity. UMass physics professor Scott Hertel contributes to this experiment, which took data from 2013 through 2016.
An experiment hall nearly one mile underground at Sanford Underground Laboratory, being refurbished for the LUX and LZ experiments. Great depths are required to reduce background radiation from cosmic rays and make sensitive neutrino and dark matter searches possible.
The installation of photomultiplier tubes (PMTs) for the LUX dark matter experiment. The PMT array is held together by a copper frame of extreme radiopurity, and great care must be taken during construction to avoid contamination of the experiment with dust or even the natural radon typical of the air we breath.
A view of the interior of the ATLAS detector at CERN, during installation and prior to the inner detector being rolled in. The barrel toroid structures are visible, as is the muon big wheel, in the background.
A cut-away view of the ATLAS detector. The magnetic toroid for the muon system, which is a focus of the UMass Atlas team, is displayed in gray.
