21. The resultant higher event rate poses important challenges for the particle detectors located in the collision areas. 22. Galileo carries 10 scientific instruments, including an energetic particles detector that automatically shut down before reaching Ganymede. 23. "' Soudan 2 "'was a particle detector located in the Soudan Mine in Northern Minnesota, United States. 24. "' Soudan 1 "'was a particle detector located in the Soudan Mine in Northern Minnesota, United States. 25. Particle detectors , used at CERN for pure scientific research, are now used in hospitals for medical imaging.26. Optical fibers doped with a wavelength shifter are often used to collect scintillation light in particle detectors . 27. Emulsion detectors are still used by some modern particle detectors ( for example, the OPERA experiment ). 28. Canadian universities and Canadian industry have contributed components to ATLAS, one of that accelerators large particle detectors . 29. Semiconductor detectors have found broad application during recent decades, in particular for X-ray spectrometry and as particle detectors . 30. Particles that are produced in accelerators must also be observed, and this is the task of particle detectors .
