| 单词 | counter |
| 释义 | counter Any device for detecting and counting objects or events, often incident charged particles or photons. The latter devices usually work by allowing the particle to cause ionization, which creates a current or voltage pulse. The pulses are then counted electronically. See Cerenkov counter; crystal counter; Geiger counter; proportional counter; scintillation counter; spark chamber. These names are often applied merely to the actual detectors; the ancillary counting mechanism is then called a scaler |
