High-speed, low-noise Secondary Electron detectors for conventional in-chamber mounts, with photomultiplier tube (PMT), integrated High Voltage (HV) supply and adjustable preamplifier. A selection of PMT diameters and mechanical housings are available to fit different chamber sizes. Voltage divider is integrated into the PMT socket for minimum noise, and an optional HV output is availalbe for monitoring.
Each SE detector is tested in house for noise peformance, using dedicated bench-test equipment and standard procedures.
