Description

The Undulator Structure with Servo-Controlled Jaw Movement Mechanism (USJMM) is a highly advanced system specifically designed for the assembly of Permanent Magnet Planar Undulators used in research facilities like RRCAT. It features two 2.5-meter-long aluminum girders/jaws that move synchronously up and down using precision-grade linear motion guideways and ball screws.

Key highlights of the system include:

• Synchronized Motion: Equipped with four servo motors, the motion of all motors is interlocked for precise alignment.
• Precision Measurements: The jaw tilt value for each jaw is measured using a high-resolution tilt meter (0.0001 degrees) with repeatability better than 0.0002 degrees.
• Feedback Control: Absolute Linear Encoders are used for accurate position feedback in a closed-loop control system.
• Load Handling: It can handle an attractive force of approximately 60 KN between girder assemblies.

This undulator structure also features a robust PM Block Assembly holder and interlocked jaw motion for consistent and reliable operation.
