10. Coldbox and FRESCA Shut Down
B163: Project Status - Planning
It is proposed the shut down of B163 will have two phases:
Coldbox and FRESCA – 17 weeks from 5th August, ending 29th November 2019.
LHe supply to small cryostats will be maintained using local dewar.
All B163 – 5 weeks from 21st October, ending 22 November 2019.
Intention is to begin operation of small cryostats and FRESCA independent of commissioning of FRESCA 2.
MSC test plan not confirmed.
