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.
