Control apparatus, kratzky block, control method and control program

A control method for controlling an X-ray analysis apparatus for a laboratory and acquiring an X-ray scattering image for morphological analysis of a molecule with the size of the 1000 Å order, the control method comprising:

• setting an arrangement condition including an opening degree and a height of a Kratky block;
• controlling the Kratky block so as to satisfy the arrangement condition;
• irradiating a measurement object with a direct beam of X-rays narrowed down by the controlled Kratky block;
• acquiring X-ray data scattered by the measurement object;
• and
• setting a center position of an opening of the Kratky block as the arrangement condition at a position different from a center position of the direct beam.

A non-transitory computer readable recording medium having recorded thereon a control program for controlling an X-ray analysis apparatus for a laboratory and acquiring an X-ray scattering image for morphological analysis of a molecule with the size of the 1000 Å order, the control program causing a computer to execute:

• setting an arrangement condition including an opening degree and a height of a Kratky block;
• controlling the Kratky block so as to satisfy the arrangement condition;
• irradiating a measurement object with a direct beam of X-rays narrowed down by the controlled Kratky block;
• acquiring X-ray data scattered by the measurement object;
• and
• setting a center position of an opening of the Kratky block as the arrangement condition at a position different from a center position of the direct beam.
