Low-Noise Profile Grid Cables for SEM-Grids and Multi-Wire Proportional Chambers for the FAIR Facility

The transverse ion distribution is analysed with secondary-electron emission profile grids and multi-wire proportional chambers. Both detector types are equipped 64 wires per transverse plane. For the connection of the 128 detector signals to the readout electronics about 350 low-noise 32-channel signal cables will be required. Wire currents cover 10 decades and range from 0.1 nA up to several Ampere for slow and fast pulses, respectively. These signal cables are to be produced and manufactured according to specification. This includes the production of 1500 meters of custom-specific multi-core cable as well as the manufacturing of the required numbers of signal cables in different lengths. For the heavy-ion synchrotron SIS100, additional 30 longer cables are to be manufactured. In this latter case, the low-noise multi-core cable is already available and will be delivered to the successful applicant by the GSI beam instrumentation department.
