  Thermal management of optomechanical devices, such as mirrors and monochromators, is one of the main bottlenecks in the overall performance of many X-Rays beamlines, particularly for Sirius: the new 4th generation Brazilian synchrotron light source. Due to high intensity photon beams some optical devices need to be cryogenically cooled and a closed-loop temperature control must be implemented to reduce mechanical distortions and instabilities. This work aims to describe the hardware design of a multi-channel driver for vacuum-ready ohmic heaters used in critical optical elements. The device receives PWM signals and can control up to 8 heaters individually. Interlocks and failure management can be implemented using digital signals input/outputs. The driver is equipped with a software programmable current limiter to prevent load overheating and it has voltage/current diagnostics monitored via EPICS or an embedded HTTP server. Enclosed in a 1U rack mount case, the driver can deliver up to 2A per channel in 12V and 24V output voltage versions. Performance measurements will be presented to evaluate functionalities, noise, linearity and bandwidth response.

  The CompactRIO (cRIO) platform is the standard hardware choice for data acquisition, controls and synchronization tasks at Sirius beamlines. The cRIO controllers are equipped with a processor running a Real-Time Linux and contains an embedded FPGA, that could be programmed using Labview. The platform supports industrial I/O modules for a large variety of signals, sensors, and interfaces. Even with many commercial modules available, complex synchrotron radiation experiments demands customized signal acquisition hardware to achieve proper measurements and control system’s integration. This work aims to describe hardware and software aspects of the first custom 8-channel differential digital I/O module (compatible with RS485/RS422) developed for the Sirius beamlines. The module is compliant with cRIO specification and can perform differential communication with maximum 20 MHz update rate. The features, architecture and its benchmark tests will be presented. This project is part of an effort to expand the use of the cRIO platform in scientific experiments at Sirius and brings the opportunity to increase the expertise to develop custom hardware solutions to cover future applications.

The beamlines and front ends at Sirius, the Brazilian 4th generation synchrotron light source, require monitoring and protection systems for personal and equipment safety in general, due to the high beam power dissipated along the beamline, vacuum safety, secure radiation levels, use of robots, special gases, cryogenic systems, and other highly sensitive and costly equipment throughout the facility. Two distinct programable logic controllers (PLC) were then deployed to create the Equipment Protection System (EPS) and the Personal Protection System (PPS). This work presents an overview of the EPS/PPS - requirements, architecture, design and deployment details, and commissioning results for the first set of beamlines.
