Controlled Entry and PPS Safety Training

Occasionally MICE collaborators will need to enter the MICE Hall when it has been searched and secured.
Since search and secure can take up to an hour a procedure has been put in place to allow controlled access.


MICE collaborators can only be allowed to carry out a controlled access if

  • they have already received CDM training
  • they have been trained in procedures for working in the MICE Hall magnetic field environment
  • they have been trained in the controlled access procedure

Controlled Access Training

Controlled access procedure is governed by

  • the Controlled Access checklist (if no SC Magnet permit is active)
  • the Controlled Access with SC Magnet Permit Active checklist if the permit is active.

Shifters should be aware of and read both of the checklists and should follow each step during the access.

three people are required to carry out a controlled access:
two workers who will make the access. Both must have been trained in the Controlled Access procedure.
one Door Operator to manage the access and keep a log of entries and exits.

Controlled access training involves:

  • PPS system principles - Hazards managed by the PPS and those outside of the system (like Stray magnetic fields, ODH, neutron monitor, LH2 beacon & PPE), show crates, door sensors etc and mimic operation
  • PPS safety aspects - Beam off Buttons, Crash outs, Status indicators by doors, Operation under Blue lights and requirement to take CE logbook under evacuation
  • Run through the "Shifter Controlled Entry checklist"
  • Go through procedure from "Hall Ready" status to "Controlled Entry" status (PK00 run key)
  • Perform Controlled Entry
  • Act as Door Operator writing in the CE register
  • Demonstrate SC permit beacon by dropping CE door bypass. Explain need to reinstate the Hall Search or Cancel the SC permit if access is required
  • Cancelling the PPS search down to "Free Access" using the "Start search" key in the main SCP.
