thk: csr
yesterday, thk representatives were here to present their product. now i am waiting for them to present a full 6dof (six degrees of freedom: xyz, and three angles) positioning solution, possibly based on the csr standard. the motors for the positioning of the linear motion (lm) blocks would be provided by omron.
the previously used positioning setup of the moller group was also based on thk, with
phytron motors. phytron is the standard at desy.
the previous thk:csr setup was normal precision grade, i.e. stable and repeatable position on a 10um scale. thk also provides super precision and ultra precision grade, with 7 and 5um precision, respectively.
with the submicron optics, we need submicron stability over 10 minutes (a low-fluence run). over 12 hours, we need 10um stability.
