LOS-ALAMOS PINHOLE CAMERA (LAPC) - A NEW FLEXIBLE X-RAY PINHOLE CAMERA

We have recently designed, built, and fielded a versatile, multichanne l x-ray pinhole camera. The Los Alamos pinhole camera was designed to fit into any 6 in. manipulator (SIM) which is a standardized target ch amber diagnostic tube. There are currently compatible SIMs available a t the Trident, Omega,and NOVA laser systems. The camera uses nine pinh oles in a 3x3 array to produce images at the film plane. The film hous ing is designed to hold multiple sheets of stacked x-ray film which al so uses a dark slide to protect the film before exposure. Magnificatio ns of 12, 8, 4, and 2X are selected by slip-on nose cones, which suppo rt pinholes, collimators, and blast shields. Individual channel filter ing is provided by a 3x3 filter pack containing nine separate filter s ub packs. Spatial resolution is limited by the pinhole diffraction lim it and held of view is dependent on magnification and filler pack diam eter. (C) 1997 American Institute of Physics.
