Introduction

Validation of the electronic design and units will be done at several levels:

• Component level, when certifying COTS components
  • Ensuring a solid rad-tolerant base, with purchase of evaluated batches.
• Sub-system or sub-assemblies
  • Allowing easier and intermediate tests.
• Complete final system
  • Finalyzing the wole project, at prototype level and only if reasonable (huge converters?).

CERN R2E Facilities Overview

Overview of the different LHC & CERN R2E Facilities spectra

2 different places are available at CERN with very different spectra, giving 2 irradiation levels for unit validation under radiations.

Inverse cumulative probability for various LHC equipment and test areas.
Curves normalized to the high energy hadron fluence.

CERN R2E Facility: CNRAD

Facility Main Characteristics

• Mix-Field (medium Ej spectra & fan cooled only & high duration exposure possible)
• Irradation of around 50 days in TSG45 area gives cumulative effect validation considered levels

CNRAD Main Characteristics Table

Facility Detailed Characteristics

Particle energy spectra (lethargy) and Inverse cumulative probability plots for line of sight location at CNRAD.
Spectra normalized per particle on target (referred to as a primary in the label), and prob. plots normalized to the high Ej hadron fluence.

CERN R2E Facility: H4Irrad

Facility Main Characteristics

• Mix-Field (high Ej spectra & Water cooled & limited duration exposure).
• 2 irradiated areas (high and medium flux).
• Reference: H4IRRAD detailed description .pdf.

H4Irrad Main Characteristics Table

Facility Detailed Characteristics

Particle energy spectra (lethargy) and Inverse cumulative probability plots for H4IRRAD.
Spectra normalized per particle on target (referred to as a primary in the label), and prob. plots normalized to the high Ej hadron fluence.

CERN R2E Facility: CHARM

Facility Main Characteristics

Future East Area Irradiation Test Facility, on PS accelerators.

• Mix-Field (high Ej spectra & Water cooled & limited duration exposure).

CHARM Main Characteristics Table

CERN R2E Facility: CC60

Facility Main Characteristics

CC60: Cobalt 60 Facility

• Colbat Co60 source on Prevessin site Building 772.
• Possible uses for low dose rate (ELDRS) as well as high dose rate.
• Active (powered, instrumented) or passive tests possible.
• Different irradiation positions: ionisation chamber for small samples or bench test for larger samples.
• Dose rate from 0.3 Gy/h up to 20 Gy/h, (good homogeneity for 7 cm x 7 cm DUT, higher possible losing precision)
• Total dose which can be reach:
  • From 1 to 10 kGy for small samples
  • Up to 100 kGy for larger samples.
