The spectrum of the TFR Tokamak has been observed in the range 5-100 Å. Identification of Mo XIV to Mo XXXIII lines originating from the limiter was achieved by comparison with the Mo spectrum emitted from a low-inductance vacuum spark, and with relativistic calculations. Some of the TFR lines were identified as forbidden transitions (electric quadrupole). The appearance of these lines depending on plasma parameters is discussed.
