A method for the experimental investigation of asymmetric cyclotron radiation in tokamaks with partial fish-scale first wall

A method for investigating the asymmetric high-frequency cyclotron radiatio n generated by asymmetric reflectivity in tokamaks with partial fish-scale first wall is presented. It is shown that the differential and average refl ectivities which, respectively, determine the passive synchrotron radiation current drive and power loss in tokamak reactors can be obtained from rela tive measurements of high-frequency radiation in existing and next-step tok amaks.
