CEDRAT TECHNOLOGIES Innovation in Mechatronics compact dynamic precise

Cedrat Technologies products for synchrotron Cedrat Technologies (CTEC) specialized in mechatronics systems has developed a specific products range for the synchrotron applications:

COMPACT DYNAMIC PRECISE 1. FAST PIEZO SHUTTERS The Cedrat Technologies (CTEC) Fast Piezoelectric Shutters FPS have been developed to provide very fine and repeatable X Ray pulses in the optical path of the continuous X Ray beamline. On top of that the FPS solved the Magnetic Shutters reliability issues. Standards products have been designed (see technical sheet below) but if you have a specific need we are able to design custom shutters. Options • Tungsten teeth • UHV compatibility • Shutter status feedback (Open/Close) with Strain Gauge (SG) sensors • Vacuum box with KF40 interface Advantages...

Cedrat Technologies products for synchrotron 1.1. FPS PRODUCT Developed in collaboration with M. CAPRIANI from EMBL (European Molecular Biology Laboratory), the fastest piezoelectric X-Ray shutter FPS200M as well as the other shutters of this products range are made of two Amplified Piezo Actuators (APA®) facing each other with a special optical head. They are mounted on a solid stage to cut a beam. When voltage is applied, the two APA® retract and the shutter opens (see Fig. 3). Fig. 3 : FPS200M 1.2. FAPS PRODUCT To tackle apertures more than 1 mm, we developed a new product range: the Fast...

COMPACT DYNAMIC PRECISE 2. FAST POSITIONER FOR FILTER ARRAY Cedrat Technologies (CTEC) has designed and produced a fast positioner for filter array composed by 6 APA600MML in a monolithic structure in collaboration with SOLEIL to reach hight performances and robustness. This project has been done in collaboration with SOLEIL for the SixS beamline to modify the energy of a beam by using a series of piezo actuated filters. Each arm is holding a filter and can move independently up to 3.5 mm with a high resolution. Related electronics • Amplifier LA75 for a high resolution position control Table...

4. SAMPLES POSITIONER Thanks to our XY or Rotation Stages and our large angle Tip Tilt products, you will be able to position your samples accurately in the center of the beam. 4.1. TRANSLATION STAGES UP TO 3 TRANSLATIONS Nano positioning to position samples Advantages • No backlash compared to ball screw devices • Accurate positioning Option • Strain Gauge (SG) sensor Related electronics • Amplifier LA75 for a high resolution position control Table e : Characteristics of piezoelectric stages

COMPACT DYNAMIC PRECISE 4.2. TRIPOD ACTUATOR The Tripod Actuator (TrAC) by Cedrat Technologies is a 3 degrees of freedom mechanism (2 rotations and 1 translation). The TraC is fitted with 3 Stepping Piezo Actuators which allow a subnanometer resolution and able to hold in position without power supply, a sample, a probe or a mirror for example.
