- Spectral studies following electron capture in slow ion-atom collisions are reported for the collision systems Kr(q+) + He (q = 7, 8, 9) at 10 keV/q. The work introduces part of the spectroscopy program which is beginning at the University of Uppsala ECR ion source facility. In particular a search was made for the 3d(10)4p2P-3d(9)4S(2)2D transitions in Cu-like Kr. This multiplet was found to give transitions with wavelengths 198.56, 194.65 and 190.97 angstrom for the 3/2-5/2, 3/2-3/2 and 1/2-3/2 components respectively.

- A 1-m normal-incidence monochromator has been designed and installed on a bending-magnet beam line at the MAX storage ring in Lund. The optical properties of the beam line have been investigated via ray-tracing studies and with flux measurements of the beam line-monochromator combination. A resolution of 0.9 Å at 919.8 Å was measured in first-order diffraction with an argon hollow-cathode lamp for slit openings of 100 μm. A photon flux of 2.0 × 1010 at 550 Å with 250 μm slits was measured with a calibrated GaAs photodiode through a 1.5-mm diameter aperture in an aluminum mask on the photodiode. The new instrument has a microcomputer controlled mechanism which optimizes focussing requirements for a scanning monochromator with the requirement of fixed slits and fixed exit beam.
