Xepr Data Acquisition

Powerful, Flexible and Easy to Use

Flexibility is key in modern research environments and Xepr supports researchers with a wide range of features to quickly and easily acquire the desired data. This flexibility is preserved across each microwave frequency band from L- to W-band and across the different spectrometer modes (CW, Pulse, and Imaging). Xepr implements a set of unique tools to facilitate routine data acquisition such as experiment control via ProDeL, the Assisted Standard Pulse Library, and Linked Experiments. All data in Xepr utilize the BES3T® format for data storage. A direct advantage of the BES3T® format is the ability to create an experiment from a saved data set reproducing all acquisition conditions, e.g. microwave power, field position, temperature, etc.

Continuous Wave EPR/ESR

The standard EPR experiment parameters are available to design 1D and 2D experiments:

Field
Time
Temperature

RF Frequency (DICE ENDOR option)
Goniometer Angle
Microwave Power

In addition, virtually all experiment parameters may be defined as an axis quantity allowing for quite complex 2D experiments. For example:

Modulation Amplitude
Modulation Frequency
Modulation Phase

Receiver Harmonic
Receiver Gain
Conversion Time

Pulse EPR, ENDOR and ELDOR

Xepr imposes no limitations on experiment design allowing researchers to fully exploit the selectivity available in pulse EPR experiments. Available axis quantities include:

Pulse Positions
Pulse Lengths
Field

ELDOR Frequency
RF Frequencies
RF Attenuations

EPR Imaging

With numerous parameters to control, EPR Imaging experiments can be daunting at first glance. Xepr lightens the burden by automatically calculating the necessary parameters need to achieve important image goals such as pixel resolution or field resolution. This feature spans the entire range of image experiments:

1D Spatial
2D Spatial
3D Spatial

1D Spatial + Spectral
2D Spatial + Spectral
3D Spatial + Spectra
