Abstract

A nickel-coated glass plate was used as a reflecting surface in the TRXF spectrometer with a log spiral bent cut-off filter. Optimal choice of the reflecting material has enabled us to lower the detection limit up to five times. A possibility to increase the spectrometer sensitivity by using an additional reflector bent into a transcendental profile to provide a required angular divergence of the exciting beam has been discussed.
