Seventy Kilograms of Xenon Took the Voltage Test
The MOTION chamber was built to study breakdown, emission and feedthrough behavior at voltages relevant to a much larger future observatory.
Summary
The MOTION chamber was built to study breakdown, emission and feedthrough behavior at voltages relevant to a much larger future observatory.
MOTION is a 70-kilogram liquid-xenon test chamber designed to operate at cathode voltages as low as minus 200 kilovolts. Its program targets dielectric breakdown, field and photoemission, and high-voltage feedthrough performance for the proposed 60-to-80-tonne XLZD detector. The paper describes test infrastructure and commissioning goals; it is not a dark-matter detection result and does not demonstrate the final observatory's performance.
Why it matters
The MOTION chamber was built to study breakdown, emission and feedthrough behavior at voltages relevant to a much larger future observatory.
