A next generation measurement of the electric dipole moment of the neutron at the FRM II
In this paper we discuss theoretical motivations and the status of experimental searches to find time-reversal symmetry-violating electric dipole moments (EDM). Emphasis is given to a next generation search for the EDM of the
neutron, which is currently being set up at the FRM II neutron source in Garching, with an ultimate sensitivity goal of 5 × 10−28 cm (3σ). The layout of the apparatus
allows for the detailed investigation of systematic effects by combining various means of magnetic field control and polarized UCN optics. All major components of the
installations are portable and can be installed at the strongest available UCN beam

A simplified D-region ion chemistry scheme and its possible use for IRI lower ionosphere modelling
Ion composition of the D region is principally characterized by the existence of two distinct regions of predominant molecular ions and predominant cluster ions, separated from each other by a rather sharp 'transition height', which is proposed to be included in the IRI as an additional parameter, supplementing the electron density models. It is possible to predict the position of this 'transition height' at a given place and time with the aid of a simplified ion chemistry scheme which is shown to be satisfactorily compatible with experimental ion composition data available in the literature. Our suggested method of this prediction makes use of the (IRI or experimental) electron density profile at the location and season in question, together with an effective clustering rate coeeficient calculated from corresponding temperature and density profiles taken from a suitable reference model of the neutral atmosphere. © 1985
