Description
The HEIMDAL thermal chopper system consists of two main sub-systems: the in-bunker Front End chopper system and the out-of-bunker TFOC chopper system. The poster is about the more complex in-bunker system which is a new design compared to the previous systems the ESS Neutron Chopper Group (NCG) has developed so far. The system houses two separate mechanical assemblies which are integrated onto a common plate along with two sets of neutron guides – thermal and cold. The whole module is located in the fully remote handling area of the bunker and the chopper assemblies need to be remotely extractable and re-installable. At this stage all of the mechanical parts are delivered to ESS and the chopper integration is ongoing.
