Christmas Light
’Twas the night before Christmas when all through the house
No electrons were flowing through even my mouse.
All devices were plugged by the chimney with care
With the hope that St. Nikola Tesla would share.

A conceptual design for a radiation-hard “pointing” fast neutron ionization chamber that is capable of delivering a 1 MHz countrate of T(D,n) events at ITER is given. The detector will use a ∼1 cm3 volume of CO2 fill gas at 0.1 bar pressure in a ∼500 V/cm electric field. The pulse widths will be ∼10 ns, enabling it to operate in a flux of ∼6×1013 DT n/cm2/sec. A special collimator design is used, giving an estimated angular resolution of 4.5 degrees HWHM.
