AbstractAbstract
[en] A facility for ultracold neutron (UCN) extraction from the ITEP heavy water reactor vertical channel is described. The facility consists of a UCN source-beryllium converter cooled with gaseous helium at 150-160 K; an oilless vacuum system based on adsorption pumps which maintains the vacuum at the level of 10-3-10-4 tor; and an external neutron guide. The UCN integral flux at the neutron guide outlet approximately 200 n/c . It is pointed out that reduction of the converter temperature up to 20-30 K and improvement of the neutronguide quality may it possible to attain the UCN flux approximately (1-2)x103 n/c
