Measurement and Analysis of Multiple Parameters of Enhanced Accelerator

The armature velocity, electromagnetic field, and spatiotemporal distribution of rail stress are important parameters of enhanced accelerators. It is extremely difficult to obtain dynamic parameters under extreme conditions. In order to obtain them, a multi-parameter measurement platform of enhanced accelerator is designed in this paper. The velocity of the armature and the magnetic field curve at a specific point are obtained by using a B probe, the spatiotemporal distribution characteristics of rail vibration displacement are obtained by using a laser micro displacement measurement device. Finally, the armature velocity, magnetic induction intensity B at a certain point in space, and the vibration changes of the rail at different times during the launch process are obtained through experiments. This work provides experimental basis for numerical calculation of multi field coupling and improving the service life of accelerators.
