WP1.6: Radiation-Hard Insulation System

• Composites for Pion-Capture Solenoid (estimated 35 MGy dose)

• RAL Technology Department Materials Group

• Steve Robertson: industrial chemist (20+ years at RAL)
• Simon Canfer: Group Leader/composite materials specialist) (18 years at RAL)

• Choice of at least two materials (or a mix)

• TGPAP (triglycidyl para-aminophenol) Epoxy-based
• qualified in a fission environment (neutron+gamma)
• to over 100 MGy
• Cyanate Ester-based
• even more radiation hard than TGPGP epoxy
• catalyst package developed at RAL

• Both systems appropriate for COMET (pending full characterisation)

• low viscosity, long pot lives and would be suitable for magnet applications
• not possible with off-the-shelf systems
