Ultracold neutrons (UCN) with energy up to the Fermi potential were stored for the first time in a volume coated with diamondlike carbon. As a function of the UCN energy and wall temperature of the storage volume, we measured the wall loss parameter {eta} and obtained {eta}=(3.1{+-}0.9){center_dot}10{sup -4} at T=290 K and {eta}=(1.8{+-}0.2){center_dot}10{sup -4} at T=115 K.
