So for a point target, the minimum angle is 58 mr or 3.4 degrees. For an extended target you will need to adjust, it becomes about 4 degree for a 15 cm target. So assume 3.5 degrees as rough number.<br />

So for a point target, the minimum angle is 58 mr or 3.4 degrees. For an extended target you will need to adjust, it becomes about 4 degree for a 15 cm target. So assume 3.5 degrees as rough number.<br />

=== NPS Dose Rate Estimates ===<br />
<br />

<br />
<br />
''Scattering Chamber Information:''<br />
<br />
::* outer diameter = 45 inches<br />
<br />
::* inner diameter = 43.125 inches<br />
<br />
::* distance beam line to SHMS window = 1.25 inches<br />
<br />
So for a point target, the minimum angle is 58 mr or 3.4 degrees. For an extended target you will need to adjust, it becomes about 4 degree for a 15 cm target. So assume 3.5 degrees as rough number.<br />
