Final answer:
WIMP stands for Weakly Interacting Massive Particles, a term related to physics and the search for dark matter. Instruments for detecting WIMPs must be large, well-shielded, and cooled to low temperatures.
Step-by-step explanation:
When WIMP instruments are mentioned as being activated spatially and temporally, it refers to a specific context within physics, particularly in the search for dark matter. WIMP stands for Weakly Interacting Massive Particles, hypothetical particles that are thought to make up dark matter. The instruments designed to detect WIMPs are extremely sensitive detectors that must be shielded from other forms of radiation and are typically placed in deep mines. They must be very large, given the low frequency of potential interactions with WIMPs, and the detectors are cooled to low temperatures to measure the small amount of energy transferred during a collision with a WIMP.
