Query: A Broad Band and Large Area X-Ray Omni Sky Monitor (BLOSM)   We present a conceptual design for a new X-ray all sky monitor (ASM).
Compared with previous ASMs, its salient features are: (1) it has a focusing
capability that increases the signal to background ratio by a factor of 3; (2)
it has a broad-band width: 200 eV to 15 keV; (3) it has a large X-ray
collection area: ~100 square cm; (4) it has a duty cycle of nearly 100%, and
(5) it can measure the position of a new source with an accuracy of a few
minutes of arc. These features combined open up an opportunity for discovering
new phenomena as well as monitoring existing phenomena with unprecedented
coverage and sensitivity.
