WITCH Experiment
WITCH (Weak Interation Trap for Charged particles) is a double Penning trap experiment to measure the recoil energy of decaying nuclei. A spectrometer in combination with a position-sensitive microchannel plate detector is used to count ions (with the MCP) while scanning their energy (using the spectrometer). The experiment is located at the ISOLDE Radioactive Ion Beam Facility in CERN. The beam from ISOLDE is bunched by REXTRAP after which it is transferred to the WITCH set-up.

Famous quotes containing the words witch and/or experiment:
“A witch is one who worketh by the Devil or by some curious art either healing or revealing things secret, or foretelling things to come which the Devil hath devised to ensnare men’s souls withal unto damnation. The conjurer, the enchanter, the sorcerer, the diviner, and whatever other sort there is encompassed within this circle.”
—George Gifford (16th century)
“Mathematics alone make us feel the limits of our intelligence. For we can always suppose in the case of an experiment that it is inexplicable because we don’t happen to have all the data. In mathematics we have all the data ... and yet we don’t understand. We always come back to the contemplation of our human wretchedness. What force is in relation to our will, the impenetrable opacity of mathematics is in relation to our intelligence.”
—Simone Weil (1909–1943)
