Facilities at Manchester

From January 2012, the Facility at Manchester has five spectrometer platforms, allowing continuous wave (c.w.) EPR at L, S, X, K, Q and W-band and pulsed EPR at S, X and Q-band. These are:

  • EMX with 1.8 T electromagnet; for c.w. L-, X-, K- and Q-band.
  • Elexsys E580 with 1.8 T electromagnet; for c.w. and pulsed S- and Q-band.
  • Elexsys E580 with 1.8 T electromagnet; for c.w. and pulsed X-band.
  • Elexsys E600 with 6 T superconducting magnet, for c.w. W-band.
  • EMX Micro X-band with 1.0 T electromagnet , for c.w. X-band EPR (77 K and above).

Available pulsed techniques are listed here.

Experimental Options:

  • sample cooling (to 1.8 K at X-band; 4.2 K for other frequencies)
  • sample heating (to 500 K) at X-band
  • single crystal mounts and goniometers
  • parallel and perpendicular mode modulation at X-band
  • in situ electrochemical generation at all frequencies
  • in situ photolysis (X-, S- and Q-band) using a ND-YAG Minilite laser (harmonics of 1064 nm, 100 mJ max power, 1-15 Hz) and spin echo detection

The Facility has a sample preparation room available in the PSI, equipped with fume hood and Schlenck line, and also full access to the chemical laboratories in the adjacent School of Chemistry. Therefore, we can handle a wide range of sample types, including samples that are sensitive to temperature, atmosphere, light, solvent loss, and a wide range of sample hazards, including toxic, biological and low-level radioactive materials.

Collaborative arrangements to other experiments:

Through established arrangements, the Facility will also help arrange access to:
