Overview

The BEST (Beamline Enhanced Stabilization Technology) is a powerful instrumentation and software suite specially designed to easily provide the capabilities for simultaneously controlling position (X, Y) and intensity (I0) of the photon beam in synchrotron radiation X-ray beamlines

The system is designed on a distributed architecture that allows installing all electronic building blocks as close as possible to the corresponding device - e.g. a piezo driver or a photon BPM. The system is composed by three main building blocks:

- the READOUT block;

- the CONTROL AND INTERFACE unit;

- the ACTUATOR block.

Direct Interfacing to the Control System of the Beamline via EPICS IOC or Webserver application

The readout block is represented by the TetrAMM device: a 4-channel bipolar picoammeter with an integrated HV bias voltage source that can be connected directly to a four-quadrant phBPM detector - e.g. diamond detector, ion chamber or quadrature diodes.

This readout block has an independent 10/100/1000 Ethernet interface for standard communication and can be also used as a stand-alone readout unit. In addition to this, the TetrAMM has a high-throughput and low-latency SFP link that guarantees interface to the control unit.

The control and interface unit is the “brain” of the entire system and it is made by a 19"-1U rack that interconnects and interfaces to the other building blocks and gives access and control to the users directly via a Gigabit Ethernet interface. The control interface has a dedicated application that allows to set the parameters to configure the beamline system (detectors, piezo actuators, geometry) and control the photon beam behavior.
