Cryogenic design for a high intensity ultracold neutron source at TRIUMF

Autor: Kawasaki Shinsuke, Okamura Takahiro

Publikováno v: EPJ Web of Conferences, Vol 219, p 10001 (2019)

The TUCAN (TRIUMF Ultra-Cold Advanced Neutron) collaboration has been developing a source of high-intensity ultra-cold neutrons for use in a neutron electric dipole search. The source is composed of a spallation neutron source and a superfluid helium
