DESCRIPTION:Speakers: Hubertus Luetkens (Laboratory for Muon Spin Spectros
 copy\, Paul Scherrer Institute\, CH-5232 Villigen PSI\, Switzerland )\nHer
 e\, we report on the status of the setup\, commissioning and first perform
 ance tests of the newest muSR instrument FLAME (FLexible and Advanced MuSR
  Environment) at PSI. Commissioning started in spring 2022 after the deliv
 ery of the superconducting experimental magnet.\n\nFLAME is designed to al
 low ZF\, LF and TF muSR measurements over a broad temperature range from 2
 5mK to 300K with magnetic fields from true zero field up to 3.5T with high
  spatial homogeneity and temporal stability. \n\nDue to its forward and ba
 ckward veto system\, it should be possible to study small samples with pra
 ctically no background. \n\nWe anticipate a time resolution of approximate
 ly 150ps due to a compact detector design allowing for high TF measurement
 s with good spectroscopic accuracy and large observable signal amplitude.\
 n\nFLAME will have the possibility to mount up to 2 samples (later up to 3
  samples) on a ladder holder on the dilution fridge which can successively
  be brought into the beam at low temperatures. This feature is thought to 
 reduce the ratio between “down” and “up” periods of the instrument
 \, which is a key factor on a heavily oversubscribed facility as SmuS.\n\n
 The magnet and muSR spectrometer are designed to be compatible with other 
 cryogenic environments already used at the μSR facility making FLAME a ve
 ry versatile instrument and ready for future upgrades.\n\nIn addition\, it
  is foreseen to use FLAME for in-situ modification of samples by external 
 stimuli like uniaxial pressure\, electric fields or electric currents.\n\n
 By the time of the muSR conference\, we will hopefully be able to present 
 the user community positive results of the commissioning of the instrument
  and of the first performance tests.\n\nhttps://indico.stfc.ac.uk/event/53
