The TUCAN collaboration is developing a next-generation spallation-based ultracold neutron (UCN) source at TRIUMF to supply high-density UCNs for fundamental physics experiments. The source's design leverages protons from TRIUMF's 500-MeV cyclotron and a large flux of cold neutrons created by a room-temperature heavy water moderator and a liquid deuterium shell, which then feed a superfluid...
First part of my talk will be an update on status of the PULSTAR UCN source commissioning at NC State University. Last year we verified expected thermal neutron flux with a real source assembly and tested gamma shielding. This year we are assembling source for the final installation in the thermal column enclosure. A first test of UCN production has been approved by the reactor and...
In this talk the current status of the UCN source project at the FRM II will be presented. Expected values for UCN density and UCN flux will be discussed. Further steps to install the source and take it into operation will be shown.
I will report on different measurements which were conducted over many years to understand operation and UCN output of the PSI UCN source.
This was done also with simulation analysis of neutron production and UCN transport.
