CERN has launched a work programme to evaluate the feasibility of a new facility for fixed target physics and dark matter searches (the “Beam Dump Facility”, BDF). In the proposed facility, a production target/dump, will be capable of absorbing the entire energy of the beam extracted from the Super Proton Synchrotron. The target will produce weakly interacting particles for investigation by a...

ISIS uses proton beam windows for both its two target stations as means of separation between the target void vessel environment and accelerator vacuum. The window with an expected life time of 20 years failed prematurely on the 19th of October 2017 after only 9 years of operation.

The extracted proton beam (EPB) windows separating the proton beam transfer lines from each neutron target stations are key components in the ISIS neutron spallation source. This work focuses on the different designs employed and their challenges on operation and replacement.

ORNL’s Spallation Neutron Source (SNS) operates its Core Vessel with a helium atmosphere in part to mitigate potential corrosion of critical components. Components within the Core Vessel are cooled by three independent water cooling loops. For the first time since SNS operations began in 2006, the presence of liquid water was detected in a Core Vessel drain in September 2016. While the...
