Spiraltron™ Electron Multipliers Spiraltron™ Series of Electron Multipliers for High Pressure Applications Applications Elevated pressures Portable mass spectrometers Residual gas analyzers Vacuum loadlocks Small ID vacuum systems Array detections, such as magnetic sector mass spectrometers Features Longer life Higher dynamic range Reduced ion feedback High performance at elevated pressures Gains in excess of 100,000,000 Noise less than 1 count/sec Excellent single ion sensitivity Small, compact linear configuration PHOTONIS USA Spiraltron™ series of miniaturized channel electron multipliers can deliver high performance at pressures up to 10-2 torr. The internal spiral structure facilitates low noise performance by significantly reducing the ion feedback typically generated from the high concentration of residual gas molecules in high pressure environments. Multichannel Construction A Spiraltron™ detector is a Channeltron® electron multiplier consisting of six individual channels fed from a common collector cone. This multi-channel configuration provides a six-fold increase in surface area compared to single channel electron multipliers, leading to longer life. The spiral section of the detector consists of six single channels which are twisted – barber pole fashion – around a solid center. This geometry results in effectively six times the output surface area and, in addition, allows a straight channel geometry since the curvature preventing ion feedback is accomplished internally. This dramatically increases detector life and dynamic range. The information furnished is believed to be accurate and reliable, but is not guaranteed and is subject to change without notice.

Spiraltron™ Electron Multipliers Benefits of Spiral Channel Technology Compact, on-axis design - eliminates need for curved channels High dynamic range with six channels - delays the onset of saturation Higher pressure operation – spiral architecture significantly reduces ion feedback Analog or pulse counting modes Long Life - extracted charge comes from six channels, not just one. Cone shape can be tailored for the application - round, square, rectangular Small, Linear Footprint Operates to 1 x10-4 torr Spiraltron™ detectors operate at elevated pressures into the 10-4 torr range, a factor...
