【 摘 要 】

There are two bolometry systems on SSPX, one that measures the total radiated power and a 16-channel array to measure the radiation profile. The first collimates the radiation through two slits in the horizontal plane spaced a distance s = 1.2 cm apart as in Fig 1. The slit heights are h = 1/100 th of an inch, and the detector material is behind the second one. The number of electrons generated per photon is proportional to the photon energy (except for a factor of 3-4 enhancement in efficiency in the visible) so that the current of electrons is proportional to the power received. The power is in turn the product of the flux hitting the detector material and the projected perpendicular area of the slab material to the line of sight (which is often at an angle to the slab).
