Pulse programs and the Bruker CryoProbe^TM

Generally, there are no special commands or particular sequences required in pulse programs for use with the Bruker CryoProbe.

However, RF peak and average power must not exceed certain limits. Simultaneous ¹⁵N and ¹³C high power pulses are not recommended because arcing can occur. Arcing will result in permanent damage to the probe.

The high quality factor (Q) for the CryoProbes greatly enhances the Radiation Damping effect. In the design of pulse programs, care must be taken to minimize the problems associated with the Radiation Damping effect.

Pulse programs marked with the C are modified for use with CryoProbes. These pulse programs are equally suited for the use with regular TXI probes.
