A cryohead (1) for nuclear magnetic resonance (NMR) measurements, comprising at least one detection channel for receiving NMR signals and at least one transmitting and decoupling channel, wherein different radio frequency (RF) coils or resonators (11, 12, 12b) are provided for the different channels, wherein the cryohead (1) comprises a heat exchanger which can be cooled by a passing fluid, in particular helium, and wherein the RF coils or resonators (11, 12, 12b) of at least one detection channel and also of at least one transmitting or decoupling channel can be cooled to cryogenic temperatures, is characterized in that at least two heat exchangers (14, 15) are provided., wherein at least one first heat exchanger (14) cools the RF coil or the resonator (11) of the at least one detection channel, and at least one further heat exchanger (15) cools the RF coil or the resonator (12, 12b) of the at least one transmitting or decoupling channel, and wherein the at least one first heat exchanger (14) is separated from the at least one further heat exchanger (15). The inventive cryohead minimizes the absolute temperature of the detection coil during operation and eliminates temperature fluctuations in the detection coil.
