6.8 Setting the magnet to the right field
The magnet is designed to be operated at 300.18 MHz with the current in the H0 Field
Coil of the Shim System set to zero. At this frequency the Synthesizers are "cleanest"
and least likely to create spurious problems
! When the lock is powered up from cold, the Field DAC is not automatically set. In order
to make sure the current in the Field Coil is set to zero,
• Open the BSMS panel.
• Set the Field Value to 2048 and switch the lock to ON once.
• Switch it off again, while the magnet is bring charged to the right field and the cryo-
shims are adjusted.
6.9 The Lock System
6.9.1 Working with the Lock System
The Fourier lock system is very similar to the BSMS lock. The BSMS Control Suite is
fully functional and for normal operation, the differences are negligible.
