X-ray Beam Monitors

english_translationfrench_translation

Sydor Technologies provides X-ray Diamond Beam Position Monitors (DBPM) to solve the alignment and feedback demands that newer, fine resolution beamlines require. Sydor provides unique monitors that utilize a custom metallized, electronic grade diamond to provide in-situ flux, position, timing and imaging. These monitors can be mated to Sydor’s intelligent, real-time feedback controllers for closed loop control. Call or email our application specialists and we can help you configure your mono, pink and white beam solutions. Sydor also provides direct X-ray detectors that span the EUV, soft, tender and hard X-ray regimes.
Sydor Stage Mount DBPM

The Sydor Stage Mount DBPM is a compact unit designed for mounting on translation stages or within small chamber areas. It includes an offset aperture that allows the DBPM to be positioned in the beam and, if required, only needs 20 mm to remove the DBPM from the beam. Typically, the DBPM remains in the beam during experiments. Sydor helps you configure the optimum mix of diamond thicknesses and metallization. Packaging designs include options for ambient/He environments to Ultra High Vacuum. The Sydor Stage Mount style employs flexible cabling sensitive to micro-positioning devices. When mated to the Sydor intelligent Beam Position Monitor I/O controller (BPMio), the Sydor package integrates the monitor’s input amps, output digitization of flux, position and timing, calibration and closed loop stage/align feedback. The BPMio integrates to the synchrotron network and GUI via EPICS or Tango.

Sydor Flange Mount DBPM

The Sydor Flange Mount DBPM includes the various flux, position, or multi-quadrant diamond configurations with cost-effective packaging for mounting onto a QF or another low vacuum flange. It can also be upgraded to a UHV configuration or customized for unique situations. Sydor’s solutions also include a dual-quad monitor utilizing two offset zones that can be used, for example, for precise K-B mirror alignment. Sydor has a variety of packages for different flange configurations, vacuum and window requirements. When mated to the Sydor intelligent Beam Position Monitor I/O controller (BPMio), the Sydor package integrates the monitor’s input amps, output digitization of flux, position and timing, calibration and closed loop stage/align feedback. The BPMio integrates to the synchrotron network and GUI via EPICS or Tango.

In-house QA and Metallization

Sydor has established impressive capabilities with partners like Brookhaven National Lab to implement DBPM development and testing. Our manufacturing capabilities allow us to offer custom DBPM metalizations, adjust cleaning and bonding procedures, and quality assurance. Sydor’s in-house test abilities include an X-ray source with an integral BPMio stage feedback system for QA verifications.

Continuing Developments

Sydor’s DBPM and detector offerings are under continuous review for further enhancements and commercialization. Sydor is awarded various SBIR/STTR grants to allow partner organizations the added R&D to continually optimize capabilities and cost.

Sydor intelligent Beam Position Monitor I/O controller (BPMio)

The Sydor intelligent Beam Monitor I/O Controller (BPMio) is a comprehensive package for the Sydor family of monitors. The unit includes input for up to 4 channels of BPM input, applies a bias voltage out, and has 6 high speed control I/O plus four programmable PID analog out (-/+10 VDC). The system can be matched to any position controller requiring pico to micro amp input requirements. The system has a full software suite and includes calibration routines. The BPMio runs in an EPICS or Tango environment.

Sydor Beam Position Electrometer (BPMem)

The Sydor Beam Position Electrometer (BPMem) is a high performance 4-channel Electrometer, specifically made for taking in beam position monitor’s pico to micro amp signals via the BPMem’s output bias voltage of 0-20 VDC, unipolar. The unit uses a 20-bit high dynamic range, with programmable gains (8) with gates from 320 µs to 1 s. The flux and position output are provided via a continuous current integrator generated from a dual integration scheme with a minimum 2.5 kHz integration resolution required.
