Find the Right Fit
Our modular systems adapt to your needs
Full Systems
Our complete UED systems include everything you need to begin time-resolved electron diffraction, right out of the box. Choose between two configurations: a compact, intensity-tuned system that controls electron pulse duration via UV excitation at the photocathode, or an RF-compressed system that boosts beam brightness by orders of magnitude — ideal for high-demand experiments requiring greater flexibility.
Both systems deliver sub-100 femtosecond temporal resolution and picometer-level spatial resolution, enabling precise insight into atomic-scale dynamics. Every system includes necessary power supplies, a fully integrated vacuum pumping system, electron optics for beam focusing and shaping, a picoammeter and Faraday cup for charge diagnostics, a high-sensitivity electron detector, and a load-locked sample exchange chamber for rapid specimen cycling and precise pump-probe alignment. Perform UED up to 100 keV with e-Ray’s full systems.
Compact Full System
Designed for simplicity, stability, and performance, our Compact Full System minimizes the distance between the photocathode and the detector, reducing space-charge effects and enabling high temporal precision. The setup uses a single magnetic lens to focus the diffraction pattern, and alignment is streamlined with a built-in load-locked sample chamber — making it easy to reposition samples with high repeatability.
This system is robust, user-friendly, and ideal for labs seeking fast setup and consistent data collection. Users can finely tune the UV photocathode intensity to match the timescales of interest: lower intensity for ultrafast dynamics, or higher intensity for improved signal in slower processes. With no extended beamline, all components are mounted directly to the accelerator chamber, resulting in an exceptionally small footprint that fits easily into most lab spaces.
RF Full System
For experiments that demand greater flexibility and more advanced beam control, our RF Full System builds on the compact design with additional beamline optics and RF compression technology. In setups where a simple footprint reduction is no longer sufficient — such as when extended propagation distances or complex experimental geometries are required — this system maintains high bunch charge density while preserving ultrafast temporal resolution at the sample.
The RF Full System includes everything offered in the compact configuration, along with several advanced components: an additional magnetic lens, two electromagnetic beam deflectors, a dedicated UV coupler for pump laser delivery, an RF-amplifier, and a sample chamber with integrated load-lock. At its core is a radio-frequency (RF) cavity that re-compresses the electron pulses to sub-100 femtoseconds at the specimen position, even after substantial beamline propagation.
To ensure precise synchronization, the system features our patented RF-Lock Box electronics module, which locks the RF phase to the femtosecond laser in your lab. It actively compensates for thermal drift and RF jitter using feedback from a pickup loop on the RF cavity — maintaining a consistent instrument response below 100 fs full-width at half-maximum (FWHM).
Electron Sources
Need a UED system but prefer to use your own electron detector? Our customizable electron source packages include everything found in our full systems — from vacuum infrastructure to electron optics — with the flexibility to omit the detector. Choose between a compact configuration or an RF-ready setup, and explore additional customization options tailored to your research needs. Inquire today to build a system that fits your lab.
RF Upgrade
Already have a UED system but want to unlock the benefits of RF compression? Our RF Upgrade package includes a 3 GHz RF cavity, an RF-amplifier, and our proprietary RF-Lock Box — the essential components needed to compress electron pulses back to sub-100 fs at the sample position.
If you’ve previously purchased a compact system from us, we’ll provide everything required to retrofit your existing accelerator chamber for RF compatibility. For labs using custom-built systems, we’ll work closely with you to understand your technical specs and include any custom beamline adapters needed to ensure seamless integration.
