ELEXSYS E600 and E680

Product Name: ELEXSYS E600 and E680

Product Description

ELEXSYS E600 and E680
The ELEXSYS family of EPR spectrometers now includes two W-band systems, the E600 and E680. The former is optimized for CW-EPR experiments at 94 GHz, while the E680 operates in both CW- and FT-mode. These high-class research instruments provide a maximum in performance and flexibility while still being easy to operate.  

Main features

  • Precise microwave power setting over a 60 dB range in W-band
  • All FT-EPR relevant parameters such as pulse power, width and phase are set and monitored on the intermediate frequency (IF) at X-band
  • High spectral purity, and sensitivity, are achieved by the combination of a fixed frequency oscillator and a PLL circuit
This setup provides an accurate final operating frequency - a must for all g-factor measurements. Flexibility in the system is assured by the modular architecture, allowing the system to be setup as a CW or a combined FT/CW instrument. System operation can be switched from CW to FT or even from W-Band to X-Band at the push of a button. The variable-temperature W-band TeraFlex probehead operates from 4 K to 300 K.
 
Samples can be exchanged at any temperature. High precision cavity matching, tuning and sample positioning mechanics facilitate high sample throughput with easy handling. For bridge and resonator tuning a 400-MHz wide tuning display is generated and detected on the IF. All these hardware features are complemented by the Xepr software with its easy-to-learn graphical user interface.

 

6 T EPR SC -New W-band superconducting magnet

The second generation of W-band super conducting magnet features a horizontal field, a main coil with 6 T sweep range, permanent leads and a 2 kG high resolution sweep coil. Both, main and sweep-coil are connected to the newly developed power supply. Easy and safe operation is accomplished by a new software interface which allows switching between the two operation modes just by a mouse click.
 

Advantages of high-frequency EPR

  • increase in spectral resolution due to the higher magnetic field
  • increase in detection sensitivity for samples of limited quantity due to higher resonator filling factor
  • increase in orientation selectivity in the investigation of disordered systems
  • accessibility of spin systems with larger zero-field splitting due to the larger microwave quantum energy
  • better separation of the ENDOR spectra of different nuclei
  • improvement in the ENDOR detectability of low-frequency nuclear spins
  • simplification of spectra due to the reduction of second-order effects at high fields
