- The precise measurement of forces is one way to obtain deep insight into the fundamental interactions present in nature. In the context of neutral antimatter, the gravitational interaction is of high interest, potentially revealing new forces that violate the weak equivalence principle. Here we report on a successful extension of a tool from atom optics—the moiré deflectometer—for a measurement of the acceleration of slow antiprotons. The setup consists of two identical transmission gratings and a spatially resolving emulsion detector for antiproton annihilations. Absolute referencing of the observed antimatter pattern with a photon pattern experiencing no deflection allows the direct inference of forces present. The concept is also straightforwardly applicable to antihydrogen measurements as pursued by the AEgIS collaboration. The combination of these very different techniques from high energy and atomic physics opens a very promising route to the direct detection of the gravitational acceleration of neutral antimatter.

- The past few years have seen the creation of the first production level Grid infrastructures that offer their users a dependableservice at an unprecedented scale. Depending on the flavor of middleware services these infrastructures deploy (for instance Condor,gLite, Globus, UNICORE, to name only a few) different interfaces to program the Grid infrastructures are provided. Despite ongoingefforts to standardize Grid service interfaces, there are still significant differences in how applications can interface to a Grid infrastructure.In this paper we describe the middleware (gLite) and services deployed on the EGEE Grid infrastructure and explain how applicationscan interface to them.
