Narrative:

IFR flight to lns under VMC [I was] vectored by harrisburg approach for right downwind for runway 26 lns. [I was] cleared for landing on runway 26 by lns tower. Descending into base leg for landing; and saw other traffic; a high-wing cessna climbing at same horizontal distance from runway; probably within 300 ft vertical separation. Lns has radar; I was never alerted to this traffic. After traffic passed over me; I heard the other traffic announce to tower that they had passed me. I feel that tower should have vectored the other traffic away from the arrival end of the runway; and alerted me to their presence.
