      abstract     = {Nickel(II) selenide (NiSe) was investigated as a new
                      high-current target material for cyclotron production of
                      radiobromine, as it contains a higher amount of selenium and
                      has a lower melting point than the widely used Cu2Se. Using
                      a slanted target system, NiSe was successfully tested up to
                      beam currents of 16 μA so far. With regard to the
                      isolation of no-carrier-added (n.c.a.) radiobromide from the
                      target material, an improved dry distillation device with
                      high yields of $76\% – 86\%$ was developed. The
                      implementation of a special custom-made quartz funnel
                      decreased the dead volume of the apparatus and a quartz
                      capillary for trapping the radiobromine allowed to
                      concentrate the radioactivity in a small volume of less than
                      100 μL of 0.1 M NaOH, ready for immediate subsequent
                      radiosyntheses. Thus, the new apparatus improves the
                      handling of the isolation procedure and the radioactive
                      product. The radiochemical purity of the resulting solution
                      of n.c.a. [*Br]bromide was verified by radio-IC where no
                      other species were detected.},
