Application for beam shuttering – X-Ray Collimator 240

The Pure Edge 240 collimator is a system for adjustig the size of an output beam. Worldwide, users of synchrotrons have different requirements regarding the output beam. One very important aspect is adjusting the size of the beam-square. ALS at Lawrence Berkeley National Laboratory used to change the aperture size by swapping different size pinhole apertures. The pinholes are used in low temperature environments. Thus, the replacement of pinholes used to be very time consuming. The manual system had to be heated up; reconfigured and then cooled back to operating temperatures.

piezosystem jena developed in cooperation with LBNL a new system, which provides different size beam-squares very precisely within a few milliseconds. The device is called the Pure Edge 240 collimator. It is based on 2 orthogonally oriented piezo slits “PZS 4SG”. It enables the customer to adjust the area of the beam within 240 µm range with a repeatability of just a few nanometers. Two NV 40/3 CLE controllers are used to adjust the Pure Edge 240 collimator. Settings can also be controlled using a PC.
