In science:

Producing bent crystal deflectors of required size and curvature is not an easy task, moreover as one takes into account that deflector has to be placed in a circulating beam and any extra disturbance to halo particles must be avoided. It took several years in IHEP to approach the target set by theory.
Crystal simulations: the road from the SPS to the LHC
The O-type has straight sections (“legs”) while Stype is bent uniformly without straight parts. Apart from the choice from the crystal deflectors already available, it is important to understand what kind of crystal should be optimal for future studies.
Crystal simulations: the road from the SPS to the LHC
This conclusion agrees with the IHEP experimental practice where typical inefficiency achieved with S-type crystal has been 0.15 (i.e. efficiency of 85%) while O-type crystals have shown inefficiency of 0.35-0.60 (i.e. efficiency of 40-65%), i.e. performance factor of 2-4 weaker than that of S-type crystal deflectors.
Crystal simulations: the road from the SPS to the LHC
New experimental tests would be decisive for the theory. A new bent crystal (strip-type deflector produced in IHEP) is now replacing the O-shaped crystal in the Tevatron .
