The Sydor Electrometer is a high-performance 4-channel Electrometer intended for use with Sydor’s Diamond Beam Position Monitors. The electrometer takes the readout currents from the DBPM and manipulates the signals with two programmable gains, the first from 1 pA-120 nA and the second from 100 pA-865 nA. The system has a full software suite and can run in both an EPICS or Tango environment.
The electrometer is Experimental Physics and Industrial Control System (EPICS) compatible and the control GUI is tailored to allow intuitive monitoring of the current signals, beam position and beam flux. The currents are measured continuously by dual integrators on each channel which operate in tandem and integrate at a rate of 2.5 Ksamples per second. Through Sydor’s software, the readout can be set for single shot or continuous acquisition. The channels also have 2 programmable gain ranges (1 pA – 120 nA) and (100 pA – 865 nA) and a large 20-bit dynamic range.
Sydor’s software also provides the capability of acquiring and displaying time series samples of the horizontal and vertical positions, total current intensity, and individual channel currents. The Sydor Electrometer allows the customer to deploy control and diagnostic systems for the optimization of beamline optics and other beamline-critical components.
Sydor Electrometer Features:
- Independent pA to nA current measurement with an integrated adjustable bias voltage output.
- Intuitive software controls via ethernet for beam position and intensity monitoring
- Continuous current integration via a dual integrator scheme
- Compatible with EPICS
