Claim:
1. A detector arrangement for detecting at least one of rays, ions and particles, the arrangement including: a plurality of detectors, each for detecting the at least one of rays, ions and particles, each detector having a respective anode output for outputting a charge upon detection of the at least one of rays, ions and particles at the respective detector, the plurality of detectors arranged with the respective anode outputs being in an electrical series; a plurality of resistive elements, each resistive element having a resistance value, being interspersed in the electrical series with the anode outputs of the plurality of detectors; a first measurement point at a first end of the electrical series and a second measurement point at a second end of the electrical series; electrical circuitry, electrically connected to the first and second measurement points for receiving electrical signals/pulses from the first and second measurement points, and for using the electrical signals/pulses from the first and second measurement points to determine which of the plurality of detectors has detected the at least one of rays, ions and particles; and a switch interposed between at least first and second groups of the plurality of detectors, the switch having a closed position in which the electrical series is provided continually between the first and second measurement points, and the switch having an open position in which the electrical series is electrically isolated into two groups of detectors, with each group being electrically connected to only one of the first and second measurement points.
