Electron Paramagnetic Resonance Facility (EPR)
The Electron Paramagnetic Resonance (EPR) laboratory houses a Bruker EMXPplus EPR spectrometer that operates on a microwave frequency range: CW X-Band (9-9.8GHz). Liquid Helium and Nitrogen cryostats. Other accessories are available for running EPR experiments at a wide range of temperatures. The EPR is located in the basement of Maeser Lab (ML) room 062.
Microwave Frequency: CW X-Band (9.0 - 9.8 GHz).
X-band Solid State Ultra Low Noise Microwave Bridge (200 mW max leveled source output, 60 dB max attenuation, 60 MHz tuning range).
Integrated Bridge Controller with real time display (automated tuning and cavity matching). Full Ethernet control of all functions.
Digital Ultra High Resolution Hall Field Controller (100 G - 18 kG operating range, up to 0 - 18 kG in one scan sweep range).
High Linearity Modulation Amplifier Module: 500 Hz - 120 kHz
High Sensitivity Probehead with optical window for CW-EPR in X-band (up to 10 mm sample tube access, 20 G max modulation amplitude, automated cavity matching, unloaded Q > 15,000, sensitivity weak pitch: 1800 : 1).
Liquid helium cryostat: 4 - 100 K.
Time Scans (kinetics studies)
2D (a second parameter can be varied along with the magnetic field)
Cryogenic experiments:+ VT unit, using liquid nitrogen, range: 100 - 500 K.
+ Liquid helium cryostat, range: 4 - 100 K.
If cryogenic experiments (especially He temperatures range) are planned, please notify NMR/EPR Manager at least 2 weeks in advance. He needs to order the cryogens and prepare the system.
