For drawing purposes only First and Third angle projection system is used. The second and fourth angle system is not preferred due to overlapping of lines of views and clear figure cannot be obtained in these two methods. First angle System In first angle system the object is placed in first...
Cygnus is a proposed global network of large-scale gas time projection chambers (TPCs) with the capability of directionally detecting nuclear and electron recoils at \gtrsim keV energies. The primary focus of Cygnus so far has been the detection of dark matter, with directional sensitivity providi...
