HIPPIE beamline offers the time-resolved APXPS with chemical perturbation and internal synchronisation using gas pulses. The time resolution achievable in the Catalysis Cell is 140 ms. Details of the setup could be found in the recent publication. Please contact Jan Knudsen for further details of the setup or if you want to apply for the beamtime with this instrument.

Method of gas pulsingGas composition pulses are formed by switching of Mass Flow Controllers
MFC range0.5 sccm – 30 sccm
Minimum pulsing period3 s
Typical pulsing period1 min – 2 min due to cell volume
Maximum sampling frequency7 Hz
Time resolution~ 140 ms
Data analysisData analysis software for the internal synchronisation signal search is available from the beamline on request. Help with the software usage ca be provided on request
