Deflection Module
Ultrafast electron techniques for crystallography
The Deflection Module sweeps electron beams with femtosecond precision. An RF cavity operating in TM-110 mode creates a transverse magnetic field that deflect passing electrons. Electrons arriving at different times get kicked in different directions.
Two applications. For diagnostics: sweep the beam across a detector to measure pulse duration with sub-100 fs resolution. For pulse selection: sweep the beam across a slit to chop a continuous beam into ultrashort pulses.
The cavity uses a dielectric-loaded design that achieves 3 mT on-axis field at just 15 W input—compact and power-efficient. A bellows mount lets you move the cavity in and out of the beam path. The module ships complete: precision-machined TM-110 mode RF cavity, 15 W amplifier with phase- and amplitude lock, thermal controller, and control software. Active phase- and amplitude lock electronics synchronize the RF to your reference signal.
Specifications:
- Frequency: 1.5-3 GHz - adaptable to your laser / reference
- Quality factor: Q > 4000
- On-axis field: 3 mT at 15 W
- Applications: streak diagnostics, chopping
Doctor X makes research instruments that give scientists control over time, energy, and measurement at a precision that wasn’t accessible before.
Doctor X works alongside research institutes, universities, and industry partners worldwide. These collaborations with engineers, scientists, and inventors matter, as they share a commitment to making instruments that unlock new research. These are our peers.
Together, we continue to move beyond science dreams.
X LAB is where Doctor X develops the next generation of ultrafast electron techniques. This is the heart of the company - where ideas become instruments.
Research here pushes beyond current products. Rotating mode cavities for faster pulse repetition. Pulse shaping for application-specific beam profiles. X-ray generation through the Smartlight project. Each direction opens new capabilities for researchers who need them.
The work happens the same way it always has at Doctor X: making, testing, refining, and sometimes discarding. Not every idea becomes a product. The ones that do will extend what ultrafast electron techniques can unlock - and what researchers can discover.
