WITCH (standing for "Weak Interaction Trap for Charged particles"), or experiment IS433, was a double Penning trap experiment to measure the recoil energy of decaying nuclei. A spectrometer in combination with a position-sensitive microchannel plate detector (MCP) was used to count ions while scanning their energy. The experiment was located at the ISOLDE Radioactive Ion Beam Facility in CERN. The beam from ISOLDE was bunched by REXTRAP after which it was transferred to the WITCH set-up.[1]
The WITCH experiment completed its run in 2015, with its successor being the WISArD experiment currently running at ISOLDE.[2][3]
