Prototype of LZ Dark Matter Experiment Gets More Sensitive ‘Eye’
The prototype for the future LUX-ZEPLIN (LZ) dark matter experiment has gotten a more sensitive “eye:” A team at KIPAC, led by postdoc Alden Fan, has put together an array of 32 light sensors in a small-scale version of the future experiment, which will use nearly 500 of them.
The sensors, called photomultiplier tubes (PMTs), will detect light flashes emitted when hypothetical dark matter particles bump into xenon atoms inside the LZ detector.
Compared to the previous version of the prototype, which used a single PMT, the array will collect light up to 10 times more efficiently and will also be sensitive to the position in the detector where a light flash occurred. The tests, which are expected to take several months, begin at SLAC in October 2017.
