Title: Deep Lens Survey
Abstract: This Survey will produce the first unbiased maps of the large-scale structure of the mass distribution beyond the local Universe. We will obtain very deep multicolor imaging of seven 2^\circ fields, which we will use to measure the shear of distant galaxies induced by the mass of foreground structures. These weak-lensing observations are sensitive to all forms of clumped mass and will yield unbiased mass maps with resolution of 1\arcmin in the plane of the sky (~ 120 h^-1 kpc at z=0.2), in multiple redshift ranges (with (Delta) z=0.5 z). These maps will measure for the first time the change in large scale structure from z=1 to the present epoch, and test the current theories of structure formation, which predict that mass in the low-redshift Universe has a particular filamentary/sheetlike structure. These unique observations will constrain the clustering properties of matter, most notably \Omega_\rm matter and \Omega_(Lambda), and, when compared with the results from microwave background anisotropy missions, will test the basic theory of structure formation via gravitational instability.
