An apparatus for the production of circularly polarised VUV radiation

Heinzmann U. An apparatus for the production of circularly polarised VUV radiation. Journal of Physics E: Scientific Instruments. 1977;10(10):1001-1005.An apparatus for the production of circularly polarised vacuum ultraviolet (VUV) radiation up to 9 eV is described. A photon beam of high intensity and polarisation is used for the photoionisation of atomic and molecular vapour beams in order to obtain spin-polarised photoelectrons. The radiation source and the polariser are discussed in detail. Results of intensity and polarisation measurements are presented
