Motivation
• Protect personnel against radiation hazard during the tests- Access to underground areas around Points 8 and 7 (and the
arc in between) must be fully operational during the test
- Access doors must be interlocked to disable beam in a failsafe way if safety conditions are violated.
• Test the access control and safety system- Procedure:
• patrol, • nominal operation,• incident management
- Access Equipment - Interlock chains- Control system

Access requirements
• Temporary interlocked gate in Sector 7-6: - To allow safe continued access to 6-7 the gate should be placed at
800 m from IP7(RP study). • Dead zone or confined space
- The machine access point at Point 7 (PM76) shall be operational. • The machine access point at Point 8 (PM85) shall be operational. • The access point between the experimental service cavern and
the LHCb experiment shall be operational and the shield wall in place (PZ85)
• Temporary interlocked gate in Sector 8-1

Installation
• Underground access system equipment in sectors 7 / 8 shall be installed before the hardware commissioning.
• Pits head access equipment could be installed during cool down, expected lower traffic.
• During the PM installation the PZ will remain operational.
• Estimation of 500 people that needs the new access card

Authorisation
• Authorisation during the tests will be given by the DSO or the GLIMOS, final decision by OP
• Enrolment campaign and new identifier distribution- New identifier included in the dosimeter
Biometry Enrolment Personal Dosimeter with identifier

Access Procedure
• Before- If necessary access control with restricted list- Patrol
• During (17 days)- Access closed and interlocked- If access necessary : LHC access mode RESTRICTED
• After- Supervised Radiation Area
• Access doors NOT required to define these limits.• Personal Dosimeter required
- New LHC access system will be operational in 7 & 8

Conclusions
• Goals- Ensure personnel safety (radiation hazards) during the tests- Test the access system itself
• More particularly the interlocks and supervision part
• Installation of access system equipment and necessary service is scheduled and organised to achieve this goal.
• 20 % of the final LHC access system- Little specific- Operational procedure to be prepared and tested
• Access system for LHC Injection Test will be coordinated by S.Grau.
