Scope of the RadMon
Measure the Total Ionizing Dose , the Displacement Damage and the High Energy Hadron Fluence in order to:
Monitor the Radiation Level in the LHC tunnel
Design and install new equipment
Anticipate the electronics degradation
Investigate the cause of failures
Simulation benchmarking
EFFECTS
SEE DD
TID
Memory
PIN Diode

RADMON V5
Specifications
It is a fully commercial system
It is radiation tolerant up to 80 Gy
It is possible to have a Deported Unit to increase the range of measurements
It is able to communicate with an industrial bus present in the LHC (WorldFIP)
It has to be capable of monitoring the three axes of the radiation effects (SEE,TID and DD).
Characteristics
SRAM as HEH fluence monitor
SRAM as Thermal neutron monitor
RadFETs as TID sensor
PIN Diode as DD

7. BATMON V5 and RadFet in CC
BatMons
Based on the RadMon V5
Battery powered RadMons
Useful for on-the-fly measurements for certain locations
The battery can last around 3 months
Can be read only during the installation and technical stops (NO online measurements)
RadFets in CC
Measure the dose in passive
Can be place in very harsh environment
Calibration up to 4KGy (during this year we plan to have a calibration up to KGy)
RadFet

RadMon V6 architecture
Actual RadMon version is the V6
Several improvement from the previous version
Radiation tolerance
Re-programmability
Self Diagnostic
Modular system
Based on COTS component
All the components have been tested for TID - DD - SEE
The entire system can stand up to 200 Gy

Measurements capability for the V6
TID
Minimum detectable with the RadFet 100nm is 80mGy (GND biasing) or 27mGy ( +5V biasing) ( factor of 10 better than the V5 )
Maximum reachable dose is 4 kGy
HEH Fluence
Possibility to measure up to 1e5 pp/cm2
Thermal neutron measurement in parallel
1 MeV neutron fluence
Minimum detectable is 1e7 n/cm2
