Trigger / RC 3 Power feedthroughs Power consumption: +6V, 610 mA -6V, 120 mA +12V, 25 mA 2) MUX-16 with driver Low multiplicity events! MUX-16 is a very fast 16 channel multiplexed preamplifier shaper and discriminator combination with very good energy and timing resolution. Up to 2 simultaneously responding channels are identified and 2 amplitudes plus the 2 corresponding amplitude coded addresses are switched to a bus. 8 modules = 128 channels can be connected to one bus, so only 4 channels of peak sensing ADCs are needed to digitize energy and position signals. The modules are especially well suited for single hit applications (maximum two hits on one module) with single or double sided multistrip silicon detectors or multiwire proportional chambers. Due to low power consumption (1.45W for 16 ch) the MUX-16 PCB can be used in vacuum without cooling. 185 x 100 x 16 mm3 7 feed throughs/ 128 channels

10. 3) MTM16 - MDI2 chained multiplexing, spectroscopy quality • MTM16: 16ch PreAmp, Shaper, Discriminator • Charge sensitive PA, variable gain and polarity • Timing filter & discriminator • Spectroscopy amplifier • Readout sequential or Zero suppressed • 16 boards = 256 channels to one readout bus • All setting individual and Remote Controlled • Low power consumption can be operated in vacuum The trigger signal from MTM16 is well suited as a high resolution timing signal. The MDI2 provides two TDC channels About 500 ns after the "gate" signal, the MDI2-sequencer is started and produces the clock sequence for reading out the MTM16. The incoming analog amplitude data are digitized by a 12 bit sliding scale ADC If above threshold, stored together with the ch address in a memory (fifo). After conversion ready the data can be accessed via VME bus.
