The toroidal analyser endstation is a custom spectrometer built by La Trobe University, for performing ARPES measurements. The unique toroidal electrode geometry allows for rapid and wide momentum space mapping. The system is moved onto the Spectroscopy Branchline during beamtimes, and in between beamtimes is able to perform offline ARPES measurements using a high intensity vacuum ultraviolet lamp. Recent addition to the system include a scanning tunnelling microscope (STM) and 2D delayline detector. The system features a dedicated chamber for sample growth, preparation cleaning, cleaving. Sample can be cooled to cryogenic temperature for measurement. The toroidal analyser is an advanced instrument, and requires users with UHV experience to be able to run properly.
