This work describes the tests performed with a newly built hollow-cathode lamp to ensure its capability to measure atomic parameters such as transition probabilities accurately. We discuss the design of the lamp and the experimental setup that will be used to measure transition probabilities. We show the discharge characteristics of the lamp and also the stability of spectral emission of the lamp over a period of two hours. Finally, it is concluded that the experimental setup, the lamp, and a camera with high resolving power are well suited for the measurement of the transition probabilities of doubly ionised rare-earths like Nd III.
