RAMSES Project Status report - Technical aspects
Presented by D. Perrin (TIS/RP) on behalf of the
RAMSES team (ST/MA, TIS/IE TIS/RP)

RAMSES Project
Mandate / Scope

• The RAMSES will provide LHC, and finally CERN,
  with an integrated RAdiation Monitoring System
  for the Environment and Safety covering
  acquisition, transmission, logging and display
  for the LHC machine, LHC experiments and
  experimental areas.
• TIS will exploit this system to assess radiation
  risks and to control the release of
  radioactivity.
• The system will also be incorporated into the
  accelerator and experiment control rooms.
• The mandate of the project team covers the system
  specification, prototyping, tendering,
  installation and integration of radiation
  monitors and industrial control equipment for
  safety systems.

RAMSES Project
Major functions

• Monitoring radiation variables (real-time)
• Measurement of dose rates during LHC operation
  around the accelerator, in experimental areas and
  their annexes, on the surface and in the
  environment (prompt radiation)
• Measurement of radioactivity in released gases
  and fluids (radioactive nuclides)
• Measurement of induced activity during LHC
  stop/shutdown
• Generation of local radiation alarms and
  transmission of remote alarms
• Generation of interlocks
• Long term data storage
• Measured values
• Events (radiation alarms, technical alarms,
  system faults, etc)
• System configuration

RAMSES Project
Major requirements and constraints

• LHC design (strong dependency)
• Distributed Radiation Monitoring network
• Flexible and modular design for easy
  configuration
• Integrated software infrastructure (control rooms
  and networks)
• Operational 24/24 hours a day, 365/365 days per
  year
• Industrial components
• State-of-the-art radiation monitors and
  monitoring stations.
• International standards for radiation protection
  instrumentation
• Valid for the replacement of the current
  radiation monitoring system (ARCON)

RAMSES Project
Mandate / Scope
Radiation monitors
The radiological safety of the LHC will be
ensured by the on-line measurement from about 350
radiations monitors of 15 different types spread
over the 8 access points, both surface and
underground installations.

RAMSES Project
Fully redundant server Centralises data coming
from the stations Stores the data in the database
(measured values, alarms, configurations) Surveys
the correct operation of the RAMSES (technical
alarms) Acts as server for the different HCI of
the system (real-time and historic
data) Integrates RAMSES into CERN control
infrastructure
19
RAMSES Project
CERN will use Data Exchange Module to integrates
RAMSES in the LHC control infrastructure Transfer
radiation alarms to the LHC control room
(CAS) Transfer technical alarms to the TCR
(CAS) Provide displays for radiation monitoring
in the LHC control room Provide displays for
monitoring conventional parameters in water
releases (for TCR) Sharing measured values with
external system (e.g. LHC Experiences)
