Facilities

X-band cw spectrometer

Almost every sample sees this machine first. Students are trained on it as well. Operating almost 24/7.

• Bruker ElexSys E500 @9.6 GHz
• Temperature range 3K-500K
• cw-EPR and cw-ENDOR

Ultra-wideband pulsed X/Q-band EPR spectrometer

At 12 GS/s with 5 GHz analog bandwidth and with an in-built sequencer, the arbitrary waveform generator (AWG) source enables new types of experiments..

• Agilent M8190 12 GS/s AWG & SP Devices 2 GS/s digitizer
• Magnetic field up to 1.5 T & Temperature range 4 K-300 K
  
• 1 kW power at X band, 200 W at Q band

S-band pulse/cw spectrometer

A versatile, octave frequency, high power, cw/pulse spectrometer, often the key to the solution.

home-built @2-4GHz
4 microwave channels, 1 kW power
probe pulse arm, magnetic field step units
home-built resonators
temperature range 4 K-300 K

X-band pulse/cw spectrometer

Commercial, sensitive and comfortable (except the software), one of our workhorses.

Bruker ElexSys E580 @9.6GHz
pulse/cw EPR, pulse ENDOR
1kW microwave, 2.5kW rf power
temperature range 2K-300K

Home-built Q-band spectrometer

Reliable highly sensitive workhorse for distance distribution measurements between nitroxide or Gd(III) labels.

pulse and cw EPR, pulse ENDOR and ELDOR @34.5-35.5 GHz
200 W microwave power
temperature range 4.5K-300K
Bruker ElexSys acquisition system (E580)
home-built TE001 cw/pulse probe (OD 3mm sample tubes)

X/Q-band pulse/cw spectrometer (Bruker)

After an upgrade to high pulse power and with using a home-built resonator for oversized samples, this is one of the most sensitive DEER spectrometers worldwide and also a good compromise between concentration sensitivity and resolution for ENDOR.
Bruker ElexSysII E600 @9.7GHz, 34 GHz
magnet field up to 1.5 T
ENDOR and ELDOR capability, temperature range 4.5 K-300 K
150 W mw power, home-built TE001 pulse probe (OD 3mm sample tubes)
