ELEXSYS-II E600/680

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. Thus all of the advantages of high frequency EPR become readily accessible.

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.

样品可以在任何温度下交换。高精度的腔匹配，调整和样品定位力学促进了易于处理的高样品吞吐量。对于桥梁和谐振器调谐，在IF上生成并检测到400 MHz宽的调谐显示。XEPR软件及其易于学习的图形用户界面辅以所有这些硬件功能。

• The high magent field required for W-band operation requires a superconducting magnet, however not all superconducting magnets are sutiable for EPR. Thus the EPR 6T SC was developed with EPR spectroscopy in mind.
  
• As high frequency EPR, in particular pulse EPR, has evolved so have the desires of the EPR spectroscopist. Depending on the pulse EPR experiment, certain advantages are available with more microwave power. For such situations, we offer two W-band bridge upgrades.

对于脉冲EPR测量值，需要短脉冲和大型激发带宽（ESEEM，鹿和FT），可以使用三个W波段桥升级：2 W，400 MW和100 MW高功率升级。具有标准W波段谐振器的400 MW高功率升级可实现脉冲长度（90^o) of 16 ns. While the 100 mW High Power Upgrade routinely achieves pulse lengths (90^o）40 ns。
The benefits of the 400 mW High Power Upgrade are easily observed in the 4-pulse DEER Experiment. The shorter pulse lengths lead to a higher signal to noise in the DEER spectrum which translates to a decrease in measuring time when compared to the longer pulses needed with the 100 mW High Power Upgrade.
