Micro beam collimator for XRD investigations alata resolution with conventional diffractometer.

摘要

A micro beam collimator for compressing X-ray beams for use in a X-ray diffractometer, wherein said collimator (1) has channel means for providing a channel guiding said X-ray beams, said channel having a portion of channel input (38) and an outlet portion of the channel (39), said channel means being formed by two half opposing plate, elongated, polished (10, 11), characterized in that said plate means (10, 11) they are flexible and are made of or coated with a material selected from the group consisting of heavy metals and materials having properties comparable to those of heavy metals total reflection, and wherein said collimator adjusting means (19, 20, 21 , 22) for adjusting the longitudinal profile of said channel and / or the opening width of said channel entrance portion (38) by bending said plate means (10, 11).
