Stephen Gallimore (STFC)28/10/2024, 10:30Facility overview, updates and developments. Operational experience of targets, beam windows, cooling and ancillary systems.
The 16th December 2024, will mark 40 years since neutrons were first produced at the ISIS pulsed neutron and muon facility at STFC Rutherford Appleton Laboratory in Oxfordshire, UK. Since that date, the facility has operated several types of targets and added muon capabilities and the second target station (TS2). This talk will provide a brief history of the targets employed, touch on some of...

Jei WEI (FRIB, MSU)28/10/2024, 11:00Facility overview, updates and developments. Operational experience of targets, beam windows, cooling and ancillary systems.
The Facility for Rare Isotope Beams (FRIB) is a scientific user facility for nuclear science. FRIB’s superconducting radio frequency (SRF) linear heavy-ion accelerator can accelerate all the ions up to uranium to energies above 200 MeV/u. The design beam power is 400 kW, which, once achieved, will extend the heavy-ion accelerator power frontier by more than one order of magnitude. FRIB...

Peter Rosenblad (Oak Ridge National Laboratory, Oak Ridge, Tennessee, USA)28/10/2024, 11:30Facility overview, updates and developments. Operational experience of targets, beam windows, cooling and ancillary systems.
The Second Target Station (STS) project is an expansion to the existing Spallation Neutron Source (SNS) in Oak Ridge, TN. The project is at the end of the preliminary design phase. STS seeks to provide world leading peak cold neutron brightness to a suite of new instruments, eight of which are included in the project scope. SNS is currently in the final stages of the Proton Power Upgrade...

Ruiqiang Zhang (Institute of High Energy Physics, Chinese Academy of Sciences (CAS))28/10/2024, 13:30Facility overview, updates and developments. Operational experience of targets, beam windows, cooling and ancillary systems.
The China Spallation Neutron Source (CSNS) marked its inaugural operational milestone by generating a neutron beam in August 2017. In August 2018, it passed national acceptance and officially started operation. The CSNS target station is distinguished by its stationary tungsten target and three distinct moderators: Decoupled and Poisoned Hydrogen Moderator (DPHM), Coupled Hydrogen Moderator...

Mr Yuanguang Xia (Spallation Neutron Source Science Center)28/10/2024, 13:55Facility overview, updates and developments. Operational experience of targets, beam windows, cooling and ancillary systems.
The Proton Beam Window (PBW) of the target station is one of the key equipment in China Spallation Neutron Source (CSNS). The PBW 1 has been running stably since2018. The PBW 2 has been completed and is planned to replace PBW 1during the CSNS summer maintenance in 2024.

This will be the first time to replace the PBW at CSNS. As an extremely important task, it poses great difficulty, tight... -
Dr Wen Yin (Institute of High Energy Physics, CAS)Facility overview, updates and developments. Operational experience of targets, beam windows, cooling and ancillary systems.
The target station converts high energy (1.6GeV,62.5µA) protons into lower-energy (< 1 eV), short-pulsed neutron beams optimized for the neutron scattering instruments. The interaction between the pulsed high-energy proton beam with the light water-cooling tungsten target produces the fast neutrons through the spallation reaction. Then the fast neutron will be moderated into short the cold,...
