Resonator ion-beam balancing
Advantages
- No stresses induced in quartz part while ion-beam treatment
- Possibility to balance axisymmetric quartz parts with overall dimensions from 15 up to 60 mm
- Emergency automatic shutdown systems
- High accuracy of resonator frequency splitting measuring system (0,2mHz at 10mln Q-factor)
- Wide range of monitored masses 10-2-0,5*10-7 g
- High accuracy of residual mass defects for the first three harmonics after balancing 3*10-5 g
