The SPECS hemispherical analyzer PHOIBOS 150 can be equipped with a mini-Mott Spin Detector for electron spin resolved data acquisition. The detector allows the parallel acquisition of spin resolved and non-spin resolved data. The non spin resolved data are acquired with six standard channeltrons. The spin resolved data are measured using a mini-Mott polarimeter of the Rice university design. This detector uses four channeltrons and allows to determine two spin components.
