A short response time atomic source for trapped ion experiments

Area of Science:

• Atomic physics
• Experimental apparatus design

Background:

• Ion traps are commonly loaded using atomic beams.
• These beams are typically generated by resistively heated ovens.

Purpose of the Study:

• To demonstrate a novel atomic oven with fast control over atomic flux density.
• To ensure reproducible construction of the atomic oven.

Main Methods:

• Design and construction of a resistively heated atomic oven.
• Systematic study of the oven's limiting time constants.
• Testing with Calcium-40 (⁴⁰Ca) atomic beams.

Main Results:

• Achieved fast control of atomic flux density.
• Reached the desired flux level in 12 seconds with no overshoot.
• Identified potential for even faster response with pre-use heat treatment.

Conclusions:

• The developed atomic oven offers significant improvements in speed and control for ion trap loading.
• Further optimization through heat treatment may enhance system performance.
