    There are different versions of the Model 3007 - the Model 3007 and the Model 3007B. The difference is the detector’s boron moderation. The Model 3007B has more boron modera- tion, which helps with the over-response of the 5 keV region.
  • Page 20 It is located to the left of the detector connector. If a headphone jack is not in use, the Model 3007 may optionally be provided with an RS232 serial output for connection to PC or other electronic device.

(A five-meter cable can be provided if requested. However, any cable longer than two meters may have issues with some USB hubs and computers, typically lap- tops.) To connect an instrument to the computer, please connect one end of the USB cable to the instrument first, and then the other end to the computer.

  • Page 79: Advanced Features

    DVANCED EATURES 7.1 Dead Time Correction All pulse counting detectors have a “dead time” in which the detector is unable to register another event. In relatively low fields this is not an issue. However, as the field strength approaches the high end of the detector’s range, dead time causes the pulse rate to become non-linear with respect to the real radiation field.
