• Change Proposal
  • 28/05/2015 To change the relief circuit for the absorber insulating vacuum from a dedicated line going via a relief valve situated inside the gas panel to making use of the existing vacuum pumping line, incorporating a bypass of the turbomolecular pump and parallel relief valves upstream of the backing pump.

  • 08/06/2015 To change from hydrogen being stored locally in a hydride bed and controlled via a heater-chiller in a closed loop, to storage in standard pressurised bottles and vented during an empty cycle.

  • 06/08/2015 To change from the successfully tested R&D vessel to the MICE experimental system, i.e. a thin-windowed absorber vessel housed inside the magnet beamline.
