Calorimetric Wire Detector for Measurement of Atomic Hydrogen Beams
Calorimetric Wire Detector for Measurement of Atomic Hydrogen Beams
A calorimetric detector for minimally disruptive measurements of atomic hydrogen beams is described. The calorimeter measures heat released by the recombination of hydrogen atoms into molecules on a thin wire. As a demonstration, the angular distribution of a beam with a peak intensity of $\approx 10^{16} \,{\rm{atoms}}/{(\rm{cm}^2 \rm{s})}$ is measured …
