Introduction

• What is FiDeL?
• A set of equations to describe the functional
  dependence of the field and field errors
• A set of parameters to fit the equations to the
  measured behaviour of the set of magnets
• What is LSA?
• LHC Software Architecture
• A set of supervisory control applications based
  on common framework

After time tinj a prediction of the snapback is
required
Corrections applied as a function of time during
the injection plateau
