THPHA070	Multiplexer for the Em# Electrometer	1548
	P. Sjöblom, A. Milan-Otero, A.G. Persson MAX IV Laboratory, Lund University, Lund, Sweden
	Small currents need to be measured from a number of devices at a synchrotron and its beamlines. To meet this demand, MAX IV have joined a collaboration with ALBA to develop an electrometer that will ensure low current measurement capabilities and seamless integration into our Tango control system. The electrometers 4 independent channels can measure accurately in the fA range. Many devices produce larger currents and only need low sample rate. To make the electrometer more flexible, MAX IV have therefore developed a multiplexer with 8 independent channels. The multiplexer is both powered and controlled by the electrometer through its multipurpose IO interface. At most, an electrometer can control 4 multiplexers simultaneously giving a system with 32 channels, but the number of multiplexers can be chosen freely. The offset current introduced by the multiplexer is 45 pA and the noise is 3 pA. The offset is eliminated by settings in the electrometer. Current sweeps shows that currents steps as small as 10 pA can easily be measured and that switching time between channels before a steady signal is achieved is limited by the filter needed by the electrometer and not the multiplexer.
