Electron spin takes important roles in spin-orbital and strong correlation interactions, which are responsible to almost all novel phenomena in condensed matter physics and the measurements of electron spin is very important for understand the mechanism of fundamental condensed matter physics.
Along with the innovation of image type multichannel electron analyzer, the measurements of electron energy and momentum achieved a notable development. On the other hand, the commercial available electron spin polarimeters are all single channel type and multichannel spin polarimeter is highly demanded.
We developed an image type multiple channel electron spin polarimeter [1] based on VLEED method. The design considerations, performance test and the results of spin-resolved ARPES measurements on PdBi2 and PtBi2 using this equipment will be presented.
