3300 SERIES MCP/RAE SENSOR HEADS
|
The 3300 Series are Open-face, MCP-based, position-sensitive detector heads for particle and EUV/X-ray detection on standard or coated (e.g. CsI, KBr) MCP surface, operated in vacuum (fully UHV-compatible). In operation, single incoming events (particles or photons) impact the MCP surface and result in an electron cascade, the gain depending on the number and type of MCP's, the bias voltage and the MCP configuration. The MCP's operate in a gain-saturated mode to ensure a relatively constant gain from event-to-event to optimize position determination. Sensor heads are offered in circular active areas of 18 mm, 25 mm, 40 mm and 75 mm diameter, and also a 74 x 93mm rectangular active area. Capable of spatial position resolution of 100 (standard) or 400 (high resolution) effective resolvable elements across active area. Spatial position linearity is typically within 5% of true position (of sensor active dimension, fixed pattern). Background count rate are typically less than 10 events per second integrated over the entire image area. Bias voltage requirements for the microchannel plates and RAE position encoder must be provided by external 2-3 kV (3-4 kV for high resolution versions) power supply and resistive biasing network.
