【 摘 要 】
We report on the design of a support unit for the radio frequency (RF) coils of a Larmor diffractometer (LD) eliminating fluctuations of the Larmor phase resulting from thermal expansion of the support structures. The key component defining the spacing between the RF coils is a Zerodur bar with a very low thermal expansion coefficient (α = 7 × 10-8K-1). This support unit will allow for LD measurements on the 10-6accuracy level even if the ambient temperature is fluctuating.
