HIPPIE beamline offers the time-resolved APXPS with chemical perturbation and internal synchronisation using gas pulses. The time resolution achievable in the High-Temperature Cell is ca. 70 ms. Details of the setup can be found in the recent publication. Please get in touch with the beamline team for further details of the setup or if you want to apply for the beamtime with this instrument.
| Excitation method | Gas pressure/composition pulses are formed by switching Mass Flow Controllers. Temperature pulses are created by rapidly changing the heating laser power |
| MFC range | 0.5 sccm – 30 sccm |
| Minimum pulsing period | 3 s |
| Typical MFC pulsing period | 1 min – 2 min due to cell volume |
| Maximum temperature ramp | 20 deg/s |
| Maximum sampling frequency | 17 Hz |
| Time resolution | ~ 70 ms |
| Data analysis | Data 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 |
| Availability | Available for general users |
