Abstract: The Design concepts of an asymmetric magnet pole undulator-prototype is presented. The asymmetric magnet pole undulator is designed with upper and the lower magnet arrays of 25 mm and 50 mm period lengths respectively. Novel features of the magnetic measurements of the magnet arrays are presented and analyzed with an alternate tunable end-termination scheme. The lower 50 mm period array employs a vertically magnetized end half magnet with a provision of 3.125 mm longitudinal movement. The end magnet of the upper magnet array with 25 mm period length has a scope of vertical movement of 3.125 mm. We propose to minimize the field integral by longitudinal and vertical movements of the end half magnets.
