Compression Module
Ultrafast electron techniques for crystallography
Electron pulses spread due to velocity differences. Additionally, space-charge repulsion can stretch femtosecond bunches into picoseconds over just centimeters of drift. The Compression Module reverses this.
An RF cavity operating in the gigahertz range applies oscillating electric fields along the beam axis. Electrons arriving early get decelerated; electrons arriving late get accelerated. The bunch compresses as it drifts downstream - from tens of picoseconds back to sub-100 fs at the sample position.
The cavity achieves 2.5 MV/m on-axis fi eld strength at 100 W input, with Q > 8500 for stable operation. Active phase- and amplitude lock electronics synchronize the RF to your reference signal.
The module ships complete: precision-machined TM-010 mode RF cavity, 100 W amplifi er with phase- and amplitude lock, thermal controller, vacuum housing, and control software. Positioned downstream of Photogun Module or existing electron sources.
Specifications:
- Frequency: 1.5 to 3.5 GHz
- Quality factor: Q > 8500
- On-axis fi eld: 2.5 MV/m at 100 W
- Compression: typicaly 100x, from 10 ps to 100 fs
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.
