Cathode spot types and spot motion of arcs in ultra high vacuum have been investigated with large area cathodes that consisted of two adjacent pieces of Mo and Cu. Arc currents were 20-60 A dc and 8-20 kApulse (duration about 1 ms). Two spot types occured with different velocities and surface erosio
