Experimental facilities

Gothenburg Photon Factory

The Gothenburg photon factory is equipped with a wide range of fixed as well as tunable wavelength lasers. There are continuous wave lasers and pulsed lasers ranging from nanoseconds to femtoseconds. It is one out of three laboratories that constitutes the network Laserlab Göteborg (LLG), which in turn is part of the Swedish network Laser Lab Sweden (LLS). The list below shows the lasers available at Gothenburg photon factory:
• High rep-rate Ti:Saphire Laser (Laser Quantum, <30fs, 1 GHz, 800 nm)
• YAG Pumped OPO-system (Spectra Physics, 6ns, 10 Hz, 220-2000 nm)
• YAG Pumped OPO-system (LaserVision 6ns, 10 Hz, 1350-5000 nm)
• Femtosecond laser system (Clark, 30 fs, 1 kHz, 470-1600 nm)
• Narrow bandwidth Ti:Saphire laser (Home built, 100 ns, 7 kHz, fundamental + frequency doubled light)
• YAG-Pumped dye laser (Sirah, 6 ns, 10 Hz, 300-900 nm)
• 3st high power diode lasers (Laser quantum,cw 2 W, 2 st 532nm, 1 st 660 nm)
• YAG and dyelaserpumped DFG/OPA-system (Sirah, 2600-3600 nm och 5500-7100 nm)

The GUNILLA ion beam facility

Our in-house studies of negative ions are conducted at the experimental facility GUNILLA (Göteborg University Negative Ion Laser LAboratory), which is a negative ion accelerator with three beamlines. Negative ions are produced in a sputter negative ions source, mass selected in a 90° degree sector magnet and finally directed into one of three beam lines. The first is a collinear interaction equipped with a neutral particle detector. An electric potential can be applied to its interaction region in order to Doppler tune the frequency experienced by the ions. The second beamline is equipped with the angular resolved electron spectrometer PEARLS (Photoelectron Angular Resolved Linear Spectrometer). The third beamline, finally, is designed for studies of highly excited doubly excited states and double detachment studies. It is equipped with a field ionizer, an electrostatic analyzer and a position sensitive detector.

Below follows some of the technical specifications of GUNILLA:

Ion source: Peabody sputter ion source
Beam energy: 3-6 keV
Mass resolution: 400 for atoms and 700 for molecules
Vacuum: 10-9 mbar in detection regions
Interaction regions: Crossed and collinear interaction regions
Detectors: Neutral particle detector, Beam scanners, Faraday cups, RoentDek Time and Position sensitive MCP Delay Line Detector.
