“…Thus, collinear arrangements of the lens and energy analyzer are desirable. There are several proposals for energy analyzers with a collinear arrangement, [23][24][25][26] such as the Wien-filter-type energy analyzer shown in Fig. 1, where an electric field and a magnetic field are applied perpendicular to the path of the emitted electrons.…”

“…the E-vs-k spectral function) are taken simultaneously in an energy interval of several eV width, limited by the chromatic aberration of the instrument. For a length of the drift section of 900 mm and a time resolution of the DLD of 150 ps, the energy dispersion is E/meV = 0.255 (E d /eV) 3/2[99]. Drift energies E d between 30 eV and 4 eV thus lead to theoretical energy resolutions of E = 40 meV down to 2 meV, respectively.…”

This article reviews photoemission experiments that simultaneously resolve at least two of the following degrees of freedom: space (real and momentum space), time (intrinsic time scale of a fast experiment or time-of-flight) and spin. In the spatiotemporal domain, imaging of fast processes by PEEM gives direct insight into plasmon dynamics or magnetization processes. In the category real space & spin the novel concept of imaging spin filters is discussed. In the time & spin chapter we address time-of-flight spin detectors and ultrafast spin processes that are accessible by pump-and-probe techniques. A main part of the paper is devoted to the resolution of momentum-space & time. This is implemented in form of the time-of-flight momentum microscope, a very recent development of which the first instrument has been in operation since 2014. In an extended outlook chapter, the potential of new developments and of a novel, highly parallelized delay-line type electron detector will be discussed. The combination of all three degrees of freedom k-space, time & spin is emerging through the combination of the ToF momentum microscope with imaging spin filter. Outline

“…The time-of-flight (ToF) momentum microscope is a joint development of the University of Mainz and the Max-Planck Institute in Halle, in continuation of earlier work on ToF PEEM [13][14][15][16][17][18]. Implementation of a ToF section as energy-dispersive element bears the advantage that photoelectron momentum maps can be taken simultaneously in an energy interval up to several eV width.…”
