Description
In this talk we present the status of the HZDR laser test facility for investigation of gas parameters in micro-gap structures at high electric fields (up to 100 kV/cm) and normal pressure. This facility has the unique characteristic of using the UV radiation as instigator of a gas primary ionization in a well-defined micrometer-sized volume. The results of several three-component gases consists of iso-butane/SF6/iC4H10 will be discussed. Simulation of RPC probes with the same geometries, gas mixtures and electric fields according to the experimental setup was performed within the Garfield++ framework. A comparison of the simulation and experimental data is given. Furthermore, the current upgrade status of the facility to a higher precision and automated acquisition is explained.
