[en] Results obtained from experiments to develop a neutral-particle analyzer using a cesium (Cs) heat pipe for electron detachment are described. The Cs heat pipe analyzer, which provides a high conversion efficiency for neutral hydrogen to H^-, is discussed in detail. Also considered are the development of a compact velocity-energy analyzer for determining the energies of impurities escaping from the EBT plasma and the development of an absolute H⁰ detector using secondary negative emission from a Cu target. The assembly of these various components to achieve a low-energy analyzer is illustrated
